In 22w14a the cat type NBT was changed from an int to a resource location string. In this change the cat type "British Shorthair" (per texture name) was renamed to just "British".

The name for the texture file and the resource location ID should be the same.

Preferred fix:

Arguably the texture file name is the correct name, as there's no cat race named "British", but there are "British Shorthair" cats.
