I personally have never tried dog or cat food but I do not think it would hurt us. I think there is a bigger chance of some human foods hurting our pets. My grandma has given her Pom human food all of her life, even after the Vet and myself and most of the family have told her how bad it is for her. I know that was off topic a bit and I'm sorry. Anyway, I have heard of elderly people buying pet food as opposed to human food due to the cost difference and that is really sad. I don't understand how people can consume most pet food because the smell of most pet foods is enough to turn me off. Yuck. lol. But anyway I really don't think it could hurt us at all.
