Yes, my 12 lb kitty is my 4.4 lb pup's bestest buddy. They love each other. Although, I often think my kitty wishes the puppy would just "chill out" a little more often. I have noticed that my kitty isn't as cuddily as he used to be before I got the puppy, he used to sit on me all the time and now not so much cuz the puppy tends to chase him off or wants to play to rough a lot of the time. Still, they are good friends and play very well together.
