I take care of 6 semi feral cats I feed them dry cat food and wet food daily. The biggest can for cat food is 12 ounces and 22 ounces for dog and it's the same price. I was wondering since dry food is their main source of food would it be ok to feed them canned dog food once a day? If not I know I can get a 22 ounce can of cat food for the same price but it does have tuna in it which I know isn't good but since it's just one meal maybe not terrible.
