A cat at any stage of growth can be turned into a purple cat, and a purple cat will continue to age as normal. Players are able to turn hellcats into purple cats, however the result will not be a purple hellcat, but rather a normal purple cat. Players who have started the Freeing Evil Dave sub-quest of Recipe for Disaster can turn a purple cat into a hellcat, but when feeding the hellcat a bucket of milk, their cat will still be purple.
