My yorkie seems to have a growing hate for my 4 cats. Does anyone have this problem? We got our yorkie last May and she seems to hate the kitties more and more. She is now one year old and instead of slowly giving her more freedom in the house, I am having to take it away. She has started attacking the kitties. All 4 cats leave her alone and have never given her any problems that I know of. Maybe I am doing something wrong.
