Petey is super skinny (he looks like a bag of bones) so I was wondering about upping his fat intake. Right now he's eating Nat. Balance 1/2 cup in the morning and 1/2 cup in the evening. He looks like he's starving to death, he doesn't have worms, eats like a pig, and has lost weight due to the nasty poos of last week. What should I be feeding him? I'm not good with cooking stuff so if at all possible a dry kibble would be best. Where/how/can I find a food with less protein and more fat?
