if u only had him for a cpl days i wount freak out just yet. but try feeding when u turn of the lights, this helped get mine to start eating and to start coming out and eating when the lights are on., i wouldnt try feeders unless he is about to die. dont wanna get him stuck on feeders but then again he is a cat and should eat anything. but i would try some bloodworms, mealworms, waxworms, or earthworms, maybe some market shrimp. try diff things and try doing it when the light are all off at night.
