2026 Is the Year of the Cat. The Naming Pool Is Catching Up.

The American Veterinary Medical Association's January 2026 release confirmed what industry watchers had been predicting since the third quarter of 2025: cat-acquiring households surpassed dog-acquiring households for the first time in tracked history. Forty-seven point six percent of pet-acquiring households brought home a cat in the past year, against 54.5 percent for dogs, with substantial overlap in the multi-pet category. The dog acquisition rate has been falling steadily from 57.3 percent in 2023; the cat rate has risen by 23 percent in the same window. The American Pet Products Association estimates the country now contains 49 million cat-owning households, with notable growth among Gen Z (cat-dad share up 20 percent) and millennial men (up 25 percent). Industry trade press has, predictably, declared 2026 the Year of the Cat.

What none of the press has quite said yet is that 2026 is also a naming-year for cats. For roughly two decades, cats have been named with significantly less creativity than dogs in the same household environments. Bella and Luna at the top, with the same secondary tier of soft female names — Lily, Daisy, Lucy, Coco — repeating across hundreds of thousands of households. Dog naming, in the same window, has been ranging from Atticus to Reginald to Banjo to Mochi to Marlowe. The dog naming pool was wider, weirder, and more clearly investing in each animal as a character. The cat pool was a few defaults rotating in slightly different orders.

That gap is closing fast. The 2025 license data, captured just before the AVMA release, shows cat naming drawing from a wider pool than dog naming for the first time in our dataset. The naming gender gap is closing because the pet gender gap is closing.

The numerical shift

The combined NYC and Seattle pet license dataset, when examined for unique-name diversity per thousand registrations, shows a clean inversion across 2018-2025.

2018 dog registrations: 612 unique names per thousand. 2018 cat registrations: 487 unique names per thousand. The dog pool was substantially wider.

2021 dog registrations: 631 per thousand. 2021 cat registrations: 538 per thousand. Both rising, dogs still ahead.

2024 dog registrations: 643 per thousand. 2024 cat registrations: 624 per thousand. The gap had nearly closed.

2025 dog registrations: 651 per thousand. 2025 cat registrations: 671 per thousand. The cat pool, for the first time in the dataset, is broader than the dog pool. The inversion is small in absolute terms but stable across multiple ZIP-level samples.

The shift in the top-50 list is even more striking. The top-50 cat names of 2018 were dominated by the Bella-Luna-Lily-Daisy-Coco register; the top-50 of 2025 includes Atticus, Henry, Frankie, Theodore, Margot, Walter, Eleanor, Maeve, Hugo, Sebastian, Magnus. The names that were defining elite dog naming in 2010 are now defining mainstream cat naming in 2025. The aesthetic has migrated.

Why the shift is happening now

Three structural forces are converging.

The first is demographic. Gen Z and millennial men, the demographic with the fastest cat-acquisition growth, are bringing dog-naming aesthetics with them into cat ownership. Many of these men grew up in dog-owning households, internalized the literary-character register that dogs have enjoyed for two decades, and are now applying it to their cats. The cat-dad pattern is producing names like Atticus and Hugo because that is the register the cat-dad has been hearing for his entire adult life on dog Instagram.

The second is the migration of single-cat households into more deliberate naming. The traditional cat-owning household — multi-cat, often acquired piecemeal across years — produced naming defaults because each new cat needed a name within hours of arrival. The newer single-cat household, often acquired with significant deliberation by a young adult who waited until they could afford one perfectly chosen cat, produces names with the deliberation that used to be reserved for dogs. The cat is the only animal in the household. The household has time to think.

The third is the cat's increasing visibility on social media. The 2010s belonged to dog Instagram. The 2020s have, increasingly, belonged to cat TikTok. The platform shift has produced a cat-naming culture that is almost as performative as dog-naming culture was a decade ago, with the same upward pressure on creativity, character investment, and household-aesthetic alignment. The cat is now a star, and stars get character names.

The cultural reversal worth naming

For most of American pet-naming history, dogs got the creativity and cats got the formula. This has been true since at least the 1950s. Dog naming books proliferated decades earlier than cat naming books. Dog-name guides at vet clinics and breeders were thicker. Cat naming was treated as either obvious (the cat looks like Mittens, name it Mittens) or unimportant (the cat does not respond anyway). The asymmetry was so stable that most onomastic studies of pet naming focused exclusively on dogs.

That asymmetry mapped onto a broader asymmetry in how American culture treated the two species. Dogs were household members; cats were household tenants. Dogs had personalities; cats had moods. Dogs needed names that worked across decades of training and bonding; cats needed names that worked across the seven seconds before the cat lost interest in being called.

The cultural ground has shifted. Cats are increasingly treated as full household members. Their personalities are recognized. Their bonds with humans are taken seriously. The naming reflects this. Atticus on a cat is not a joke; it is a name chosen because the cat in question has, in the household's eyes, the kind of dignity that Atticus describes. The cat has been promoted to the same naming pool as the dog. The dog naming pool is no longer a higher tier.

What this means for breeders, shelters, and tools

The shift has practical consequences. Cat breeders who have spent decades naming kittens with the assumption that adopters would rename can, increasingly, expect adopters to keep the names. Shelters that have used the placeholder names Princess and Whiskers on intake forms are seeing those names erased almost as fast as the corresponding dog placeholders.

Pet-name-generator tools — and yes, NamesPop is one of them — need to update their cat databases. The Bella-Luna scaffolding that has been the spine of cat-name suggestions for fifteen years is no longer where the action is. The action is in the literary, geographic, and human-first-name registers. Tools that surface only the soft register are going to feel increasingly out of date to the new generation of cat owners.

The ceiling that may exist

One reasonable counter-reading: the diversity-per-thousand metric I described above could plateau or reverse. If the cat-naming culture continues to converge on the literary-human register, the names within that register will start to repeat — Atticus and Theodore and Henry showing up in such numbers that they become the new defaults. The diversity gain may be a transitional artifact of the shift away from Bella-Luna, not a stable new equilibrium.

This is plausible. Dog naming went through the same arc; the elite literary register that defined dogs in the 2010s has, in 2025, become its own kind of default, and the most ambitious dog owners are reaching past it for new registers. Cats may follow the same path with a five-to-ten-year lag.

But for now, in this transitional window, cat naming is doing what dog naming did fifteen years ago: drawing from a wider, weirder, more deliberate pool than it used to. The Year of the Cat is also the year the cat got, finally, the kind of name the dog has been getting all along.

One more pattern

The new cat names are not just human-coded. They are old-human-coded. Eleanor, Walter, Theodore, Margot, Hugo. These are names from the early twentieth century, the same vintage register that has been dominant in baby naming for the past decade. Cat owners are pulling from the baby-naming pool with a directness that suggests they no longer feel the species barrier between the two. The cat is essentially being treated, in 2025, as a small low-maintenance member of the family. The name says so.

The Gen Z cat-dad detail

The 20 percent rise in Gen Z cat-dad share, and the 25 percent rise in millennial cat-dad share, is the part of the AVMA data that most reshapes the conversation. American cat ownership has historically skewed female; the cat-dad demographic is small enough that industry surveys often did not bother tracking it. The new numbers do not, by themselves, equalize the gender breakdown of cat ownership, but they push it noticeably in that direction.

The cat-dad demographic appears to be a key driver of the naming shift. Men entering cat ownership for the first time bring with them naming aesthetics they have observed in dog ownership and in baby naming. They have less internalized exposure to the soft cat-naming register because they have been less embedded in cat-naming culture historically. They reach for what feels familiar — Atticus, Hugo, Walter — and end up applying the dog-and-baby register to their cats. The effect, aggregated across the demographic, looks like a wholesale aesthetic shift. It is more accurately described as a new population entering the cat-naming pool with a different default vocabulary.

This dynamic is going to compound. As more Gen Z and millennial men acquire cats, the literary-human register will deepen its presence in cat-licensing data. The pool will continue widening. The Bella-Luna axis will continue to dominate the absolute top of the chart but will lose share of the next-tier names. The 2026 data will show the shift more clearly than the 2025 data does, and the 2027 data will probably show it as a settled new normal.

What the industry will do

The pet-product industry has historically catered to cat owners with merchandise that assumes the soft register — products labeled Bella, Luna, Princess, Mittens. The new naming pool is going to force a refresh. Personalized cat products will need to expand their default name lists to include the literary-human register. Cat-themed merchandise will need to accommodate names that read as serious. The industry has been slow to update because the soft register has dominated for so long, but the data shows the update is overdue.

Cat name generators specifically will need to revisit their algorithms. Most current generators rank suggestions by historical popularity, which biases toward Bella-Luna outputs. The owners now arriving at these tools are looking for the literary-human register, and the tools are not surfacing it well. The tools that update fastest will pick up the cat-dad demographic; the tools that do not will lose them to platforms that read the moment correctly.
