This book is about cats. We don't do much with them here so why not? Here in Meow Animal Shelter we have only cats. And when we deliver your cat they come in cute little boxes called meow boxes. 

Then you go through all the things regular owners do. Show us what happens in rp. We control the cats you control you. 

Always wanted a pet but somebody is allergic. No problem! Come here!

(That cats smile though)
