Something extraordinary happened between 2023 and 2024 that almost no one in mainstream media covered adequately. The number of Gen Z households in the United States that owned a pet jumped by 43.5% in a single year — not 4.35%, not a rounding error, but nearly half again as many young adults choosing animal companionship over the course of twelve months. The American Pet Products Association, which has been tracking this industry since 1988, described it as a remarkable shift. The data behind it tells a story that is equal parts economic, emotional, and generational.

By 2024, 18.8 million Gen Z households owned at least one pet. The broader market they helped fuel reached $152 billion in annual expenditure — a figure that exceeds the GDP of several small nations. In the UK, Mintel's 2025 research found that 78% of Gen Z adults own a pet, a higher proportion than any other generation alive. None of this happened by accident. It happened because a generation that cannot afford mortgages, cannot afford children, and inherited an economy designed for older wealth, found something real and manageable to love. The pet industry was ready. The question now is whether it fully understands who it is serving and why.

The Numbers: 43.5% Surge — What the APPA 2025 Report Actually Says

The APPA National Pet Owners Survey is the most authoritative source of data the US pet industry produces. Released at Global Pet Expo in early 2025, the 2025 edition contained findings that surprised even industry veterans. Total pet ownership grew from 82 million US households in 2023 to 94 million in 2024 — a 15% overall increase that was itself remarkable. But buried inside the generational breakdown was the figure that changed everything: Gen Z's share of pet-owning households grew from 13.1 million to 18.8 million in a single year.

To put that in perspective, Gen Z's share of overall US pet ownership rose from roughly 11% of all households in 2018 to 20% in 2024. Ingrid Chu, APPA's vice president of Insights and Research, called it "a remarkable shift in pet ownership." APPA CEO Pete Scott noted that Gen Z and Millennials are now substantially more likely than Baby Boomers or Gen X to have multiple pets. Gen Z is also, critically, the only generation in the United States in which pet ownership is still actively growing. Every other cohort has plateaued or declined.

Dog and cat numbers both grew — to 68 million dog-owning households (51% of all US homes) and 49 million cat-owning households (37%) in 2024, rising to 53 million cat households by 2025. Gen Z accounted for 20% of all dog owners (an 18% year-over-year increase) and 20% of all cat owners (a 25% year-over-year increase). Even backyard chicken ownership jumped 28%, reaching 11 million households — a trend with distinct Gen Z fingerprints on it.

Pets Over Children: The Economic Reality Driving This Generation's Choice

The decision is not sentimental — or at least, not only sentimental. Seven in ten Gen Z adults say they would rather have a pet than have their own child, according to multiple surveys conducted between 2023 and 2025. The reasons are structural. Gen Z entered adulthood during the most hostile housing market in living memory. In 2025, the typical age of a first-time homebuyer in the United States reached an all-time high of 40 years, according to a National Association of Realtors report. Only 34% of Gen Z adults currently own their homes — compared to 43% who rent and 18% who still live with parents or family. A Coldwell Banker report found that 84% of Gen Z is actively delaying major life milestones simply to afford housing.

The cost of raising a child to 18 in the United States now exceeds $300,000 by most estimates. Student loan debt is a constant weight. Entry-level salaries have failed to keep pace with inflation for years. In this context, the choice to adopt a cat or a rescue dog rather than start a family is not avoidance — it is adaptation. "Rampant inflation and the high cost of living are making major life decisions like parenthood seem impossible and financially burdensome," financial expert Michael Ryan told Newsweek. Pets offer the emotional rewards of caregiving — love, responsibility, unconditional companionship — at a cost that is measurable and manageable for a 24-year-old earning $42,000 and paying $1,800 a month in rent.

A 2024 Mars Petcare global study of 20,000 pet owners across 20 countries found that 45% of Gen Z respondents considered their pet the most important thing in their life — a higher proportion than any other generation. That is not a niche statistic. That is nearly half of a generation telling researchers that their animal companion occupies the emotional space that previous generations reserved for spouses and children.

🩺 Clinical Perspective: As a veterinarian who has watched the client demographic shift dramatically over the past decade, the emotional depth Gen Z brings to their animals is not a trend or a lifestyle aesthetic. It is a genuine attachment style, and the health outcomes for the animals reflect it. Younger owners are more proactive about preventive care, more diligent with nutrition, and more likely to notice subtle changes in behaviour than almost any other group I treat. The animals benefit enormously from being someone's primary emotional priority.

The Multi-Pet Generation: 70% of Gen Z Have Two or More Pets

One of the most striking findings in the APPA 2025 data is not simply that Gen Z owns pets — it is the scale of ownership. Seventy percent of Gen Z pet-owning households have two or more animals. That figure makes Gen Z the multi-pet generation by a substantial margin. For comparison, 63% of Boomer households currently have multiple pets, and that proportion has been declining since 2018, when it stood at 56%.

What drives this? Part of it is the emotional investment described above. If a pet occupies the role of child or closest companion, having more than one is a natural extension. Part of it is also lifestyle: many Gen Z adults work from home for at least part of the week, meaning their animals are not left alone for long stretches. Part of it is the social media dynamic that makes multi-pet content — dogs and cats, two cats of different breeds, a rabbit alongside a reptile — enormously shareable and aspirational.

The practical challenge is that 70% multi-pet ownership among a generation that is primarily renting means ongoing tension with landlords, building management companies, and housing policies that restrict pet numbers. This is quietly becoming one of the most significant pet welfare policy questions of the next decade — how housing regulations adapt to a generation for whom a two-pet household is the baseline expectation, not the exception.

Why Cats Are Winning — And Gen Z Is Why

Cat ownership grew faster among Gen Z than dog ownership in 2024 — 25% year on year compared to 18% for dogs. By 2025, cat ownership had reached 39% of all US households (53 million homes), and the APPA's own commentary described cat growth as the strongest long-term driver in the ownership statistics. Globally, among Gen Z specifically, 69% own cats while 56% own dogs — cats are already ahead.

The reasons are practical, cultural, and algorithmic. Practical: cats cost less to own than dogs. They do not need professional walkers, doggy daycare, or the same level of outdoor space. A cat can live comfortably in a one-bedroom apartment in a way that a Labrador cannot. For a generation that is predominantly renting in urban environments with no garden, this matters enormously. A 2024 industry analysis noted that cats have "stronger long-term prospects than dogs amid economic and housing headwinds" through 2029 — precisely because their ownership demographics skew younger and their costs are lower.

Cultural: cat content dominates the internet in ways that are hard to overstate. Cat owners over-index on TikTok, Reddit, Snapchat, and Pinterest, according to Morning Consult's 2025 State of Pet Ownership report — the exact platforms that Gen Z uses most. The feedback loop reinforces itself: Gen Z sees cat content, connects with it emotionally, adopts a cat, creates cat content, reaches other Gen Z users, and the cycle continues. The most significant growth in cat ownership in 2024 was specifically among Gen Z and Millennial men — a demographic shift that would have seemed implausible ten years ago.

The Spending Gap: Gen Z Outspends Every Other Generation on Their Animals

Perhaps the most counterintuitive finding in this story is the spending data. The generation that cannot afford homes and is delaying children spends more on their pets than any other generation in the country. A Talker Research survey conducted for digital insurance company Lemonade in 2024 found Gen Z spent an average of $178 per month on their pets — compared to $146 for Millennials, $115 for Gen X, and $90 for Baby Boomers. That gap at the extremes is $88 per month, or $1,056 per year. Over the lifespan of a typical housecat, Gen Z will spend $17,952 more on that cat than a Boomer owner of the same animal.

Generation	Avg Monthly Pet Spend (2024)	Annual Difference vs Gen Z
Gen Z	$178	—
Millennials	$146	–$384
Gen X	$115	–$756
Baby Boomers	$90	–$1,056

What does Gen Z spend this money on? Premium pet food and functional treats, calming supplements (78% of Gen Z dog owners and 71% of cat owners use calming products, according to APPA), veterinary wellness plans, pet insurance, grooming services, and an increasingly wide range of enrichment products. The APPA's 2025 Bird, Small Animal and Horse report noted that Gen Z now makes up 22% of all US bird owners and 34% of all small animal owners — categories where spending on enrichment, habitat quality, and species-appropriate nutrition has been rising sharply, driven largely by social media education.

There is also a meaningful financial intelligence dimension here that is easy to overlook: despite spending the most, Gen Z is the generation most likely to have pet insurance and least likely to go into unplanned debt to cover unexpected pet expenses. The stereotype of the reckless young spender does not hold in this category. Gen Z approaches pet spending with discipline that belies their reputation — they budget deliberately, insure proactively, and research purchases through the same platforms they use for everything else.

TikTok, YouTube & the #PetTok Economy

The APPA specifically called out social media as a defining feature of Gen Z pet consumer behaviour, noting that "TikTok, YouTube, and Instagram play a crucial role in their purchasing decisions." This is not a peripheral observation. The #PetTok hashtag has accumulated billions of views. Cat videos and dog content are consistently among the highest-engagement categories on every major platform. For Gen Z, these platforms are not passive entertainment — they are where purchase decisions are researched, where veterinary advice is debated, where breed selection happens, and where the emotional experience of pet ownership is shared and amplified.

Mars Petcare's global study of 20,000 pet owners found that social media influences 13% of all pet ownership decisions — with a disproportionate effect on puppy and kitten parents specifically. Among Gen Z, that influence is substantially higher. The effect on brand loyalty is significant: Gen Z pet owners are far more likely to discover a new food, supplement, or product through a TikTok creator recommendation than through traditional advertising. Cat owners, specifically, over-index on every platform where Gen Z is most active.

This creates a fundamentally different commercial environment for the pet industry. Brands that built their dominance through television advertising and physical retail placement are competing with DTC startups whose entire distribution model runs through influencer partnerships and social commerce. The APPA's framing — that "leveraging visual and digital-first strategies will be key to capturing the attention of this rapidly growing demographic" — understates the degree to which the rules have already changed.

Birds, Small Animals & Reptiles: Gen Z's Unexpected Pet Choices

Beyond cats and dogs, the generational data reveals some genuinely surprising patterns. The APPA's 2025 Bird, Small Animal and Horse Report found that Gen Z now accounts for 22% of US bird owners — a 22% increase from 2023. They represent 34% of all small animal owners (hamsters, guinea pigs, rabbits, gerbils), up 17% from 2023. Reptile ownership among Gen Z is also notable: while the total reptile-owning population has remained steady at around 6 million households nationally, the generational composition has been shifting younger.

The appeal of exotic and non-traditional pets among Gen Z is partly practical (small mammals and reptiles are more apartment-friendly than dogs), partly driven by niche TikTok communities (ball python content, axolotl accounts, and parrot training videos have substantial Gen Z audiences), and partly an expression of identity. Gen Z approaches pet ownership with a different value framework to earlier generations: they are more likely to research species-specific needs before acquiring an animal, more likely to seek out specialist exotic vets, and more likely to see the act of learning about their pet as part of the ownership experience. The APPA report also noted that Gen X's "empty nest" phase is driving growth in birds (+25% YoY for Gen X) and reptiles (+20% YoY), creating an interesting generational intersection in these niche categories.

Backyard Chickens: The Surprise Trend Hiding in the Data

One of the more surprising findings in the APPA 2025 report was a 28% year-over-year increase in backyard chicken ownership, bringing the total to 11 million US households. While this trend spans multiple generations, it has a pronounced Gen Z dimension that connects to several of the wider themes: distrust of industrial food systems, interest in sustainability, the desire for a connection to animals and food production that feels authentic, and a broader DIY ethos that manifests across everything from sourdough baking to urban micro-farming.

The timing is also relevant. Egg prices spiked sharply in 2024 and into 2025 amid ongoing supply issues, giving backyard flock ownership an additional practical economic argument that landed particularly hard with a generation already stretching its budget. For Gen Z, chickens sit at an interesting intersection of pet, food production, sustainability statement, and TikTok content — a set of values that aligns almost perfectly with who this generation is and how it communicates.

The UK Picture: 78% of Gen Z Own a Pet — More Than Any Other Generation

The Gen Z pet ownership trend is not an American phenomenon. In the United Kingdom, Mintel's 2025 research found that 78% of Gen Z adults own a pet — the highest proportion of any generation in the country. The UK currently has approximately 34 million pets total, including 12 million dogs and 12.5 million cats, with Gen Z and Millennials having driven the majority of post-pandemic acquisition growth. UK Pet Food data found that 59% of the 3.2 million households that acquired a new pet during the pandemic were aged 16 to 34.

On spending, the UK mirrors the US pattern. A 2024 survey of 2,000 British cat and dog owners by Pet Drugs Online found that Gen Z and Millennial pet owners (aged 18–34) spend approximately £78 per month on their pets — compared to £52 for owners over 45. Gen Z allocates 17% of their pet spending specifically to toys, compared to just 8% among older generations. Both figures reflect the same underlying reality: these are owners for whom the animal's quality of life, stimulation, and emotional wellbeing are active priorities rather than afterthoughts.

The emotional dimension is equally striking. A ManyPets survey of 385 British pet owners found that 79% of UK Gen Z say they have a pet specifically for emotional support — higher than any other UK generation. A further 82% say their pet completes their family. Three-quarters of UK Gen Z pet owners say their relationship with animals is fundamentally different from how older generations experience it, and the data bears that out: from calming products to bespoke nutrition to specialist exotic vet care, the way this generation interacts with the pet industry looks unlike anything that has come before it.

Veterinary Care: The Paradox of Spending More but Accessing Less

Indeed ranked veterinarian as the #1 best job in the United States in 2025 — the first time the role has topped the list since data collection began in 2019. Veterinary job shares increased 124% between 2021 and 2024. The median annual salary is now $139,999. The demand is structural and growing, fuelled directly by a generation spending $178 a month on animals and expecting clinical-grade care for them.

Yet the APPA 2025 report also found that 37% of all pet owners are concerned about access to veterinary care. Of those, 60% cite affordability as the primary barrier, and 32% point to appointment availability. This paradox — a generation that spends more than any other on their pets, but increasingly cannot access or afford the specialist care those pets need — is one of the defining tensions in the pet industry right now. Wait times at veterinary practices have lengthened significantly. Emergency vet costs have risen sharply. Pet insurance penetration among Gen Z is growing but still covers a minority of owners.

The UK faces the same pressure. Gen Z and Millennial pet owners in the UK were most likely to cut veterinary visits and pet insurance spending when the cost of living crisis peaked in 2023 — precisely because these were among their biggest discretionary costs. The result, as StreetVet and other frontline organisations have noted, is animals presenting to veterinary care later than they should, with conditions that have progressed further than necessary. Closing this gap — between the emotional investment Gen Z makes in their animals and the structural accessibility of the care those animals need — is one of the most important challenges the industry faces.

What This Means for the Pet Industry's Future

Gen Z is currently the least financially powerful adult generation alive. By 2030, they will have collectively accumulated an estimated $36 trillion in income, and by 2035, a 2025 Bank of America report projects they will be the richest and largest generation on the planet — overtaking Millennials as the great wealth transfer from Boomers flows down. Their global consumer spending is expected to reach $12.6 trillion by 2030, up from roughly $2.7 trillion in 2024.

For the pet industry, this is not a trend to monitor — it is the central structural reality of the next two decades. A generation that already spends $178 a month on their animals while earning entry-level salaries, and that treats those animals with a depth of care that no previous generation has matched, will spend dramatically more as their incomes grow. The categories that will benefit most are premium and functional nutrition, preventive healthcare, pet insurance, enrichment products, and any veterinary model that can solve the access and affordability problem for younger urban owners.

What Gen Z has done is not simply buy more pets. They have redefined the relationship between a human being and an animal companion — treating it with the same seriousness of care, the same emotional commitment, and increasingly the same financial prioritisation that previous generations reserved for their children. The $152 billion industry they are currently fuelling is, in every meaningful sense, just the beginning.

Frequently Asked Questions

Q: How many Gen Z households own pets in the US?

A: According to the APPA 2025 State of the Industry Report, 18.8 million US Gen Z households owned at least one pet in 2024 — a 43.5% increase from 2023. Gen Z's overall share of pet-owning households grew from 11% in 2018 to 20% in 2024. It is currently the only generation in the US in which pet ownership is actively growing year on year.

Q: Why is Gen Z choosing pets instead of having children?

A: The primary drivers are economic. Housing costs are at historic highs, student debt is substantial, and entry-level wages have not kept pace with inflation. Seven in ten Gen Z adults say they would rather have a pet than a child. A 2025 Coldwell Banker report found 84% of Gen Z is actively delaying major life milestones to afford housing. Pets provide genuine emotional companionship and the rewards of caregiving at a cost that is manageable for young adults earning average salaries in high-rent cities.

Q: Do Gen Z pet owners spend more than other generations?

A: Yes, considerably more. A 2024 Talker Research survey for Lemonade found Gen Z spends $178 per month on their pets — compared to $146 for Millennials, $115 for Gen X, and $90 for Baby Boomers. That is $1,056 more per year than Boomers. Despite spending the most, Gen Z is also the most likely to have pet insurance and least likely to go into unplanned pet debt.

Q: Why are Gen Z choosing cats over dogs?

A: Cats cost less to own, suit smaller apartments, do not require professional walking, and perform better on the social media platforms Gen Z uses most. Cat ownership among Gen Z grew 25% year on year in 2024, versus 18% for dogs. The fastest-growing cat-owner demographic is Gen Z and Millennial men. Globally, 69% of Gen Z own cats compared to 56% who own dogs — cats are already ahead.

Q: What percentage of Gen Z have multiple pets?

A: 70% of Gen Z pet-owning households have two or more pets, making Gen Z the most likely multi-pet generation in the US, according to APPA 2025. Boomers' multi-pet rate has fallen to 52% and is declining as the generation ages.

Q: How is Gen Z changing pet ownership in the UK?

A: In the UK, 78% of Gen Z own a pet — the highest proportion of any generation, per Mintel 2025. UK Gen Z spends approximately £78/month on pets vs £52 for over-45s. A ManyPets survey found 79% of UK Gen Z own a pet for emotional support, and 82% say their pet completes their family. Gen Z and Millennials accounted for 59% of new pandemic-era pet acquisitions in the UK.

Conclusion

The 43.5% surge in Gen Z pet ownership in a single year is not a blip. It is the visible leading edge of a generational reorientation in how human beings relate to animals — one driven equally by genuine love and by the structural conditions of an economy that has made traditional family formation inaccessible for tens of millions of young people. Whether you view this as a crisis of unmet human aspiration or as a flourishing of the human-animal bond, the data points in the same direction: Gen Z has chosen pets, is committed to them in ways that outpace every previous generation, and is building an industry around that commitment that will only grow larger as their economic power expands.

For pet owners, the takeaway is straightforward: if you are in Gen Z and you have an animal, your instincts about the depth of that relationship are well-founded and well-supported by evidence. Invest in preventive veterinary care, look seriously at pet insurance while your animal is young, and do not underestimate the value of what that relationship gives both of you. The $152 billion industry grew this fast because millions of people discovered something that veterinarians, animal behaviourists, and pet owners of every generation have always known — that the bond between a person and their animal is one of the most reliable sources of unconditional love available to a human being, at any price.
