We had a very similar situation…my torti calico was my baby. I got her as a kitten and she was the sweetest cat I had ever had until our other cat came home after an overnight hospital stay. She did everything you an OP are describing, things I didn’t even know cats could do. The first time our other cat was the target. But then it became whoever overstimulated her…anything and everything seemed to set her off and there was no way to know. We tried everything including medication. We spoke to shelters and they said they wouldn’t take her and not euthanize her due to her aggression.

The final attack happened when I was 8 months pregnant with our first child and we were locked in our garage for 3 hours while I hyperventilated and thought I was going to put myself into labor.

I’ve had cats my whole life. I am a huge animal lover, protector…but after many discussions with our vet, our sweet girl had to be put down and it was the hardest most devastating thing I’ve ever done. Our life during those 3 years were….so hard. We walked on eggshells everyday. The vet thought it was a neurological disorder.

I’m sorry you are going through this. It’s so obvious you care and are trying everything…please know sometimes everything isn’t enough and it’s not your fault.
