Many dogs like raw or cooked broccoli, but if it has been cooked with a lot of oil or spices it may cause digestive upsets. Broccoli can cause gas in dogs just as it does in people.
Cats are not known to like broccoli, but it won’t hurt them.
Omnivorous lizards can eat small amounts of raw broccoli once a month, but it has more phosphorus than calcium and too much can cause calcium to be leached out of the bones and lead to fractures, so only feed it as an occasional treat. Cooked broccoli can cause diarrhea in lizards.
Parrots often enjoy raw or cooked broccoli, and it is safe for them. Raw broccoli has more nutrients than cooked, and parrots like to chew on the stalks and florets, which can be stuck between the cage bars or hung from the top of the cage to give them more interesting ways to eat them.
