My dog and cat have a love/hate type relationship. There hasn't been any blood shed, but I have seen my cat "smack" Rizzo when he gets too rambunctious. Rizzo is constantly trying to get him to play, but the cat has no desire to play with him. However my bf has a kitten that loves to play with Rizzo, everytime I take Rizz to my bfs place with me they just play and play and give us both some time off. Super relaxation time for us, lol, then the get so worn out that we get to sleep in
