The popularity of cat names differs by nation, even nations with the same language. The ranking of most popular cat names can be assessed, in particular, from pet insurance registrations, microchip registrations, and breed registries.
Adrian Frankllin, senior lecturer of the School of Sociology and Social Work at the University of Tasmania and author of Animals and Modern Cultures, told the Sunday Tasmanian in 2001: "In the 1950s and '60s dogs and cats were given 'dog' and 'cat' names. [...] Cats had names like 'Blackie' and 'Spotty', names that illustrated their physical appearance. The 1980s marked a turning point, with the 10 most popular dog names all being compatible as human names, but in the '90s this progressed even further. People are now giving animals the same names as contemporary names given to babies." He believed that as people have fewer children or no children at all, pets become more important in their lives.
In Australia, the United Kingdom and in the United States, news accounts have noted that the same popular baby names were also being given to pets. The new names for dogs more closely echoed human baby names, said Lindsey Basserabie, a company official, but the trend occurred for both pet species. "In fact, this year's list of top 10 dog and cat names could nearly be straight from the birth pages." In the United States, according to an article in The Tampa Tribune, some of the most popular cat names also appeared on the Social Security Administration's list of most common baby names: "Isabella (Bella) is No. 4 for girls, and Sophia ranks ninth on both the Social Security and pet lists."
According to "Bow Wow Meow", an Australian company that provides pet tags to pet stores and veterinarians, the 10 most popular cat names its Australian customers chose, as of 2010, are:

In 2006, a survey of 270,000 Nestle Purina PetCare customers in Australia came up with these most popular cat names:
Historically, the cat-specific names "Tibbles" or "Tibby" were common, and are still occasionally used. These were derived from the character of Tybalt or Tibert in the Reynard the Fox folk tale cycle, and ultimately from the Germanic name Theobald, derived from theod- "people" and bald "bold". The name was applied to cats as they were popularly thought to be daring and curious. The old cat name "Gib", a contraction of the name "Gilbert", was also thought to have arisen through the latter being used as a 'translation' of the French "Tibert". However the similar-sounding name "Tiddles", given in England to both male and female cats, was instead derived from a dialect verb tiddle, "to pet or stroke".
"Tabby", another traditional cat name, was originally used for any striped cat but later led to the widespread use of the etymologically unrelated name "Tabitha" for female cats. The cat name "Thomas" or "Tom", as well as the generic term "tomcat", appears to have been originated and popularised by an anonymous work (sometimes attributed to Fielding, although most likely by William Guthrie) first printed in 1760, The Life and Adventures of a Cat, whose hero is called "Tom the Cat"; before this time male cats were generally called "ram-cats" or "gib-cats" rather than "tomcats".
Scottish cat names included "Baudrons" or "Baudrans", an affectionate term equivalent to "puss". The word appears to be related to the dialect term bawd used for the European hare, much as the dialect names "puss", "furze cat" and "mawkin" were also recorded for the hare. In Wales, "titw" was used as a similar affectionate term for cats.
By the mid 1980s, surveys indicated that the most popular names in the UK were largely genderless and based on colour, with few personal names, although "Tabitha" remained popular and "Sam" was the most popular name for male cats.
In 2006, Direct Line, a pet insurance company, compiled a list of the most popular cat names chosen by its customers. The company's list of popular cat names "overlaps heavily with the same year's 100 most popular children's names in England and Wales", according to Melissa Lafsky, writing in the "Freakonomics" blog at the New York Times website:
Another survey conducted in 2006 came up with different results. In that poll, conducted for the Royal Society for the Prevention of Cruelty to Animals, 2,000 people in the United Kingdom were asked about their pets' names. The most popular names were:
A 1998 poll in Britain conducted for Petplan, an animal insurer, found the most popular cat names to be Charlie, Milly, Oscar, Tiger, Poppy, Sophie, Rosie, Smudge and Lucy.
The United States' largest pet insurer, Veterinary Pet Insurance (VPI), releases annual rankings of its customers' most popular cat names and dog names. The 2010 list (based on information from 2009 and released in January 2010) was gathered from 475,000 policies. Curtis Steinhoff, senior director of corporate communications for VPI, attributed the popularity of "Bella" (No. 3 on the cat list but No. 1 for dogs) on the 2010 list as probably having "something to do with Bella being the name of the heroine in a certain vampire book/film series that's pretty popular these days." In 2012, VPI (collected from information from 2011) listed the top 5 female cat names as Bella, Lucy, Kitty, Chloe and Sophie. The top 5 male cat names were Max, Oliver, Charlie, Tiger and Smokey.
In 2017, Find Cat Names compiled results from 2.2 million cat owners to find the most commonly chosen cat names from its search engine. It listed the top 5 female cat names as Nala, Bell, Luna, Abby, and Daisy. The top 5 male cat names were Simba, Milo, Tiger, Oreo, and Bear.
In 2009, the Chicago Sun-Times reported that according to government databases, the three most popular cat names in that city were, in order, Kitty, Tiger and Max. In 2004, the same newspaper reported differently based on information from the Cook County Department of Animal Control. The Sun-Times reported in 1987 that the same Cook County department had checked its database of 27,863 cats that had been vaccinated from 1984 through 1986 and found yet different results.
Finally, a Gallup poll of 1,242 Americans was completed in 1990. The results of all of the above polls are summarized in the table below:

In Germany, "'exotic English and other non-German names are popular with German pet owners", according to an article in the About.com website. Typical, clichéd names for cats in Germany include that language's equivalent for "kitty", Mieze or Miezekatze ("pussycat"). Muschi was also quite common and carries the same meanings as "pussy" in English, which led to its sharp decline as a popular name in the last 20 years.
According to another About.com article, one German list of popular cat names in that country gave these rankings:
