Steve showed up at our door about a year ago. Don't know anything about him but he wasn't fixed, needed major dental care, etc. so he wasn't well taken care of or was abandoned. He's at least 7. Anyway, we've tried to feed him everything. All he will eat is canned mackerel and salmon. No problem, used to mix it with dry. Now he won't eat if we mix it, puree it, frappe it.. He's had his teeth removed and the vet says him gums look fine and he isn't hurting, but he just doesn't like cat food. Won't eat any people food either. All he wants is mackerel and salmon. Is it OK for him to just eat those with regular vitamin/mineral supplements? Anyone have any ideas on how to get him to eat cat food?
