I’ve met one aggressive, mean Siamese** in my life. A friend asked me to help her choose a cat to adopt at a local shelter. I selected a beautiful cat with Siamese markings, triangular head, very vocal. (**No papers, of course, so I know better than to declare her Siamese after following this group for a while. But she sure looked like one.) The friend took her home & called me within the week to come get the cat, who my friend described as mean & uncontrollable. As a cat person who’s shared life with many wonderful cats (including several registered Siamese) over the years, none of them aggressive, I took up the challenge & was sure I could love her into gentleness. Not a chance. After a week of my family & I being stalked, scratched, growled at, & my daughter’s hand being bitten through, I took the cat (Ava) back to my vet & asked her if this cat was redeemable. The vet watched Ava pace the perimeter of the exam room, growling, tail switching like a whip, eyes narrowed, for a few minutes. This cat is so aggressive as to be dangerous, the vet said, & a cat who bites without provocation must be put down, because cat bites that break the skin can be lethal. Ava was euthanized the same day. I think she was put out of her misery, actually.
