I used to have a kitty who drooled when she was happy. (She passed a few years ago.) She was a grumpy thing, but occasionally she would deign to give us some love and get some in return, and after a few minutes she’d shake her head and it would go flying everywhere, lol. Sometimes I wonder if she liked living with us, being so grumpy at times, but she must not have totally hated it.

Poor sloppy drooly kitty. One of mine is pukey. I'd rather she drool. Cheers.

I don't think one eye is supposed to be big when the other is small, OP has your cat always done this?

Ya cat got some tooth decay
