I would check with the vet too, I know with dogs some things that can be extremely harmful to them is if they eat grapes or anything with garlic on it.
My grandmother God rest her soul used to feed her cat a can of crab meat everyday and then was shocked to find out the cat had diabetes, needless to say the Vet was every alarmed to find out what she was feeding the cat, lol We lived in a fishing community and a friend of the family had brought over a big garbage bag full of crab legs, she boiled them and fed them to the cat he was mortified.
