Well, when I first got Ray, he was nearly feral from the abuse that he'd suffered for the pretty much the first 6 months of his life.
We catnapped him from an evil acquaintance when we discovered that this son of a *&#$% used to get the cats (Ray & his sister) stoned. Suffice it to say, my ex knocked him on his a$$, and he and his buddy grabbed the two cats and ran out the door when he saw what was going on (my ex's only saving grace).
This poor cat was absolutely terrified, and began throwing himself against the door and walls until he either knocked himself out, or came down off the drugs, we were never sure which.
Once we could handle him (he was very dangerous) we got him to the vet who examined him thoroughly, (and called the police to have this guy charged) and told us that because of the brain damage this cat suffered, he'd never be normal. I was not about to let this beautiful, and helpless animal be destroyed, so I took him home and spent more than 6 months turning him completely around.
After many teeth marks, scratches, a tetanus shot and several rounds of antibiotics (me, not the cat) he's the biggest sook you ever want to meet

- at least with me, he's not that comfortable around anyone else.
The only side effect that remained after 9 months was that when he got excited about something, he ran into walls. The vet, who was astounded that he had turned out the way he did, thought that he was blind. So, I changed his name from "Look Out" (you never knew when he was going to pounce) to Ray Charles. Oddly enough, he liked Blues and the old R & B music, and I found that when he got wound up, he'd relax when I turned on the stereo. He particularly liked Ray Charles.
Turns out he's not blind, just clumsy.
When my ex and I broke up, I kept the cat (fought tooth and nail myself) and shortened his name to Ray, although he prefers Handsome. If you call him Ray, he looks at you and walks away.
So, why do you ask? You have a cat with the same name?
