Curiosity killed which animal in the old saying?

Player Jellybean, first time I’ve heard that second sentence

pinkey, that it does! Facts!

I watched a cartoon where it said curiousity killed the cat and was singing about it! I can’t remember what it’s called but that’s how I know this question lol!

and satisfaction brought it back..

a cat also has nine lives

so its true that the cat had a 9 lives?

Or an equal statement is "Don't open Pandora's box."
