Is peanuts safe for cats?

Peanuts are technically a legume, commonly eaten roasted and salted, or ground into peanut butter. Peanuts are not known to be toxic to cats, but they are fatty and offer no benefit to a meat-eating animal, so it is best not to make a habit of them. Cats are obligate carnivores, so they get what they need from meat and never need peanuts. If you offer it at all, treat it as a rare, tiny extra.
