I have a cat who is a very picky eater the only one she likes most is fancy feast classic and sheba premium fine foods and loaf is it safe to feed this to her? I tried giving him all flavors of tiki cat ,varieties like pate,dark, and mousse but she only likes mackerel and tuna but if I feed it continously won't eat anymore. Tried giving her merrick, halo, blue buffalo, instinct, friskies wet food she doesn't like it much. Is fancy feast classic and sheba safe to feed to her?
