cats

Then it clearly isn't somebody else's cat and it is good on you to take care of her. Seriously, people here all butthurt because I'm pointing out that it is not a good idea to feed other people's pets. And even insulting me, such entitled pricks.

When the cat is not malnurished and in good health then don't feed it. You don't know of allergies or other causes for special food. It is natural for cats to eat mice and birds, but eating other things like tuna can do damage.
