I am sorry to report that some kitties are psychotic. My oldest, Peter, was diagnosed as such by a vet. But as with anyone (human or animal) that has a mental illness, time and love
is essential to any treatment or recovery.
I was home alone and was working on some wiring down my desk for a new phone. Peter came in and wanted to see what I was doing. He smelled around and rubbed against me. So, I stopped and rubbed his ears and and petted him and gave him some cuddles for a few minutes. He got enough and squirmed, so, I let him go and he went on. I went back to work and the next thing I knew here Pete was. He jumped on my right arm with all four feet and teeth! I tried to relax and give him a second to release as he usually did with his attacks, but he didn't this time. He just dug in with a firmer grip and started ripping flesh with his back legs. I grabbed him by the back of the neck and lifted his body weight up thinking that he would respond, but no luck. Then I managed to get hold of his back feet with my left hand, but I couldn't get him to release me. By this time, I had blood dripping off my arm and he was chewing on the underside of my wrist. I finally got him around the throat, exerted some pressure, and then at last, he released me. He took off all fuzzed up and was annoyed with me for about a day. My wrist took ages to stop bleeding. Thought I was gonna have to go to the emergency room that night and it took weeks and weeks for it to finally heal up. Now I look like I have tried to slash my wrist but botched the job because the scars run long ways not across.
Please, don't send the humane society to take my cats away! I love my babies and don't normally choke them. My point is don't give up on your kitty. Time and love can make a difference for a psychotic animal. I didn't have Pete put down as many people recommended after that attack. I kept him and as it turnd out, his psychosis improved dramatically when we adopted another cat! He still has bad spells but nothing like before. And the truth is we would just be heartbroken if anything ever happened to him. Hence, the weighty vet bills from his recent bout with a virus.
Peter might just be an ill tempered, psychotic, ex-feral cat but we love him and he is one of us for better or worse. Hang in there and I'll say a pray that a solution will be presented for your situation. God bless you!
