Welcome!
I think I have heard about your cat before from Pam.
My siter & bro-in-law have a pschyco-cat. Attacks people, (sometimes including them). One time they almost were sued by an old landlord who was attacked by this cat. The only reason they weren't was that she had gone into their apt. without informing them ahead of time.
This cat has also attacked their friends, family, etc. There are alot of people who won't come to their house unless they lock the cat up first.
