RagDoll kittens in longhair class judging at the 2019 CFA International Cat Show held in Cleveland, Ohio, USA.
The judges are Wayne Harding and Darrell Newkirk.
The last "kitten", Zeus RagDoll Kunlun, is listed as a kitten in the catalog, but is being judged as an adult in Darrell's ring, so I presume he was a kitten on Saturday and an adult on Sunday. The catalog gives the cat's birth date as 02/14/19, so looks like CFA doesn't use calendar months but counts days to determine which class kitty shows in. Using an internet days calculator, looks like CFA averages months to 30 days and uses that to make the determination.
