“But cats love to be around humans and kill vermin. And then give them to humans so the humans won’t starve.”
Do you have any recipes for them vermins your cats give you?
I'm afraid not.
I used to tell my cat, when she would put a dead treat on the patio and nudge it towards me, that I was putting it a plastic bag to save for later. Somehow, I never got around to actually eating them.
