Yeah they basically suffocate from it, something around the lines of blood not transferring oxygen. Ironically my cats go nuts for it. They said buy some garlic spray thing at the pet store to stop them from scratching the couch. And the idiots lined up to lick it instead. I'm not sure if the pet store was trying to offer a "permanent" solution to couch scratching...

Yeah, I wasn't aware of that. It's crazy the kinds of things that people can eat with no problems but can make a cat sick or even kill them. Don't feed your cat friends people food!

I'll have to stop giving my kitten onion bread.

One of my cats did that to me once. 😬

Kitty rules! Also I hope you are both ok.
