I do not have them living together...however my brother has a cat (11 pounds) and My lil guy loves him he is only half his size (4.6) But they play everytime they see each other. It is quite funny they chase each other in and out of rooms like tom and jerry...Capone my little Yorkie even stands up on his hind legs and boxes right back at the cat! Just make sure your kitten is declawed so your little baby won't get scratched in the eye or anything! Let me know how it turns out.
