My 05 pastel male is not eating. He has eaten once in the past 3 months, I've done bloodwork on him and everything is okay, ive tried f/t asf's, live asf's, live mice, live rats, f/t mice and f/t rats and he just will not take anything. I really don't want to force feed him and I heard its not good for them, so I don't know what to do really...any advice?
