You didn’t mention white cats. My parents had a white cat that was possessed by satan.
I havent known a lot of white cats. They tend to be sickly. Ill make a note of the Satan thing, though.
White cats (and dogs too,) carry a recessive gene that can cause deafness. That might be a part of it.
We had a sweet little (and I mean she was tiny) white cat, deaf as a post, and I think brain damaged as well. She's just sit in the corner, staring at the wall! Then go tearing around the house, only to go back to the corner, I think maybe putting herself into "time out!"
She was so cute though. Because she couldn't hear, sometimes she'd just mouth "meow," and other times should could have awoken the dead! And she'd come up to you, sitting right at your feet, making you think that she wanted something... Look into your eyes, and then forget what she was doing and begin sharpening her claws in your shins!
