Hey guys, so I'm not sure if Mars is getting a full meal when I feed him a pinkie, his lump would disappear after about 10-12 hours. I feel that he's not having enough to eat. I've tried to move up to furries but they're too big. So my question is, would it be alright to feed him two pinkies? Is that healthy? any suggestions would be helpful. Oh and also, how long can you keep frozen mice frozen before they go bad?
