I have three cats, three yorkies...yes I have gone mad! lol! Chauncey the Ragdoll..keeps to himself, wants nothing to do with the dogs OR the other two cats. Skye is a little B with an itch...she will swipe at dogs, humans she could care less...you are in her personal space you WILL get swiped! For this reason I keep all other animals away from her...she has gotten into some nasty fights with the other cats. Darth Vader loves everyone human, or animal, he will sit and let Jersey bite on his ears, or Orion loving on him, or Raelle just chillin...he has come between the pup and miss 'b' when she decides to get nasty, being the larges of all animals he is none the worst for wear..he takes no crap from her!
In time they will work out their own arrangements, and will cohabitate peacefully....
