I have a 5 month old kitten named Zoe. She is a great little kitty, but, she seems to have two completely different personalities. Usually she is just like a normal kitten, sweet and playful. However, sometimes she turns into "Evil Zoe". I have had many kittens before and have never seen this before. She goes beyond the normal bad kitten stuff. She walks around with her mouth open just snarling and growling, she tried to kill everything (actually trying not just playing), the other cats hide from her and seem to be actually terrified. She just turns evil sometimes. My question is, is it possible for cats to have split personalities? I work with people that have mental disablities and have worked with split personalities before and it seems like the same thing. Has anyone heard of this before??
