I don't know if it was because where we lived FRESH was not always available or it was a way to stretch food for a large family or she liked to torture me? Who knows- lol.
Our cat when we first got her, Had salmon but it was flash frozen- and sauteed in a pan...She enjoyed that- So we did buy her a can, But she turned her nose up- She does love canned tuna on occasion. But shes a cat so....What do I know? We have a dog that loves bologna.
