Why do you keep throwing away the mice I bring you? I work really hard for those, and we both know they’d overrun the place if I ignored them.

You’re being a bit rude.

The vibe I get is "watch out you fucking idiot, I'm trying to be in danger"

Whenever the cats that have been in my life are doing dangerous stuff like that I hiss at them and chase them off. It's very effective at getting them to stop trying to kill themselves and it doesn't seem to upset them longterm
