How Pet Market Categories Shifted Over the Past Five Years

A data-based look at how food, veterinary care, supplies and services changed in the pet market over the past five years, and which subcategories gained share.

The pet market did not simply get bigger over the past five years. Its category mix changed in ways that matter for retailers, manufacturers and buyers. Using publicly available data from the American Pet Products Association, the clearest pattern is that recurring care categories have gained weight, while one-time or more discretionary product categories have become more selective.

In 2021, APPA reported $50 billion in U.S. pet food and treats, $34.3 billion in veterinary care and product sales, $29.8 billion in supplies, live animals and OTC medicine, and $9.5 billion in other services. By 2024, those categories had moved to $68.3 billion, $41.0 billion, $34.4 billion, and $14.3 billion respectively, according to APPA's current industry statistics page. The market still rewards broad assortment, but the growth mix now leans more clearly toward nutrition, wellness and recurring care.

Quick takeaway: Over the past five years, the pet market has shifted away from broad-based discretionary buying and toward repeatable, care-linked spending such as food, wellness, veterinary support and service-driven categories.

The biggest change was not size, but spending quality

It is tempting to read the last five years as a simple post-pandemic demand story. That is incomplete. Yes, the market expanded, but the more meaningful change is that pet owners became more intentional about where they spend. APPA said in its 2026 State of the Industry release that households are increasingly prioritizing essential care while becoming more value-oriented in discretionary areas.

That distinction helps explain why all four major categories grew, but not at the same pace. From 2021 to 2024, food and treats grew by about 36.6%, veterinary care and product sales by about 19.5%, supplies by about 15.4%, and other services by about 50.5% from a smaller base. The market did not stop buying products. It simply started rewarding categories that are tied more directly to health, daily routines and repeat purchase behavior.

Food stayed the anchor, but it changed internally

Pet food and treats remained the largest category throughout the period, but the internal mix shifted. In 2022, APPA said food and treats delivered the largest category increase, rising 16.2% year over year to $58.1 billion. That jump was partly inflation-related, but later category behavior suggests the story was not only price.

APPA's 2025 Dog & Cat Report shows a more structural change inside food. After weakening in 2023, premium food purchases regained momentum in 2024, while basic food purchases declined. The same report said 41% of dog owners and 38% of cat owners bought premium food in 2024, while mixers and toppers rose sharply from 2018 levels, up 129% for dog owners and 138% for cat owners.

That matters because it shows pet food is no longer just a volume category. It is increasingly a layered category with premium diets, functional add-ons and condition-specific nutrition. In practical terms, part of the market moved from simple feeding to nutrition management, which supports better margins and more frequent replenishment.

Veterinary and wellness spending kept gaining strategic importance

Veterinary care and product sales were already the second-largest bucket in 2021, and that position has become more meaningful over time. The category rose from $34.3 billion in 2021 to $41.0 billion in 2024. The absolute gap between veterinary care and supplies also widened, suggesting that health-linked spending is not just resilient, but structurally more defensible.

The same trend appears in wellness-related subcategories. APPA's 2025 Dog & Cat Report said 53% of dog owners and 34% of cat owners gave their pets vitamins or supplements in 2024, both up year over year. On a six-year lookback, supplement purchases were up 56% for dogs and 70% for cats. That is a strong signal that everyday wellness has become part of normal care behavior rather than a specialist niche.

This does not mean pet owners spend without limits. APPA also said in 2026 that value-seeking is rising and that some households are spending less overall. But the category implication is still clear: when budgets tighten, care-linked categories tend to hold up better than nice-to-have purchases.

Supplies became more selective, not irrelevant

Supplies, live animals and OTC medicine still grew from $29.8 billion in 2021 to $34.4 billion in 2024, but the category no longer looks like the broad excitement engine it did during the post-pandemic setup phase. In 2021, APPA said supplies posted the biggest percentage increase among the major categories at 17.8%, which reflected new-pet adoption, habitat setup and household stocking.

That momentum later normalized. By 2023, APPA was already describing the market as more omni-channel and more deliberate, with owners splitting shopping between online and brick-and-mortar rather than buying impulsively across every product bucket. In 2025, APPA further noted that spending behavior was shifting away from discretionary items toward essential care.

The more interesting point is that supplies did not vanish. They became narrower and more purposeful. APPA's public dog and cat findings suggest the winning product areas are often those tied to a use case or lifestyle signal: harnesses, training-support products, travel-oriented gear, premium litter-adjacent routines, and products that strengthen the day-to-day human-animal bond.

Services moved from rebound story to real category force

Other services remain the smallest of APPA's four major buckets, but they posted the fastest growth from 2021 to 2024. The category increased from $9.5 billion to $14.3 billion, a gain of just over 50%. Some of that reflects recovery from disrupted grooming, boarding and routine service demand after the pandemic period. But it also reflects a broader willingness to outsource parts of pet care.

This matters because service growth changes the wider category ecosystem. A service-oriented owner often buys differently: more travel products, more grooming maintenance, more wellness support and more convenience-driven items. In other words, services do not only expand their own category. They can pull demand into adjacent product categories with stronger repeat behavior.

Humanization changed which subcategories win

One of the clearest lessons from the last few years is that category change is not only about essential care. It is also about how pets are integrated into daily life. APPA's 2025 Dog & Cat Report said cat-themed merchandise purchases rose 89% from 2018, holiday or birthday celebrations for cats rose 250%, and cat harness ownership increased materially as more owners treat cats as interactive companions rather than fully indoor observers.

That may sound small compared with food or veterinary care, but it is strategically important. It shows that even inside slower-growing hardgoods, subcategories with a clear emotional role can still outperform. The market is not rejecting accessories. It is filtering out generic accessories and rewarding products that connect to lifestyle, identity or visible care behavior.

Europe points in a similar direction, but compare carefully

A European read supports the broader nutrition-first view, even if the numbers are not directly comparable. FEDIAF said in its 2026 statistics release that annual pet food sales in Europe stand at 29.4 billion euros, with around 8.6 million tonnes sold and an annual value growth rate of about 4%. That reinforces the idea that food remains the anchor category in mature pet markets.

However, FEDIAF also notes that its recent geographic coverage changed, so direct year-on-year comparisons need caution. The point is not to merge the U.S. and European numbers into one chart. The point is that two large pet markets still show strong weight in recurring nutrition and care rather than a wholesale return to novelty-led demand.

What these category shifts mean now

For buyers and category planners, the last five years suggest a more disciplined framework:

Protect recurring categories first, especially food, health support and service-linked replenishment.
Treat wellness add-ons as core merchandising, not fringe upsells.
Expect supplies to work best when tied to a visible routine, lifestyle use case or training need.
Read premiumization carefully: owners still spend up, but usually where the value story is concrete.
Separate rebound categories from structurally stronger categories before making growth assumptions.

The biggest mistake is to describe the whole pet market as either premium or price-sensitive. The market is both. It has become more selective, and category performance now depends more heavily on whether a product or service feels essential, repeatable and clearly useful.

Conclusion

The most important pet market category shift over the past five years is that spending became more care-centered. Food stayed dominant, veterinary and wellness-related spending kept strengthening, services gained more legitimacy, and supplies became more selective rather than universally weak.

That is the key lesson behind today's pet market category shifts. Growth still exists across the sector, but it is no longer spread evenly. The categories gaining the most trust are the ones closest to everyday care, health support and repeat household routines.
