Food that is poisonous to cats

Many cats are lactose intolerant, so avoid giving them cow’s milk. Make sure fresh water is available at all times.

Human food including cheese, chocolate or eggs, should be avoided as treats, unless it is steamed white fish or chicken. Keep raw dough out of reach of your cat too.
