My 3yo old male cat is constantly wanting to eat. Orginally, I would put a bowl full of food out for him and his sister to graze on, but he would finish the bowl himself and was gaining weight. So, I consulted my vet and I now feed them 2x/day, morning and night the recommended amount of food. Every morning the male has a habit of waking me up at 5am to be fed. No matter how many times I push him away and try to ignore it, he doesn't give up until I get out of bed and feed him. I've tried to lock him out of the bedroom, but he's ruining the carpet with his claws. Why is he so obsessed with food? Am I not feeding him enough?
