That's a lot of cats that guy has. I have trouble getting my 2 to get along, let alone 21. My brother and I used to name Mom's pets in a way designed to aggravate her. The one she hated most was when we called her hamsters- Boa Bites. My brother keeps snakes, he at one point had a 16 ft albino burmese named Snuggles. That was during the time we also had a young kitten kept trying to get under the door of the snake room. The kitten was Trouble because that was all he ever got into was trouble. He almost became a snack for the snake by accident.
