About 2 weeks ago my corn snake got a cut on his neck pretty close to his head, since then he hasn't eaten. I have only tried frozen mice and figured I'd give it one more shot at frozen. So I waited 4 days then tried to feed it again, I checked this morning and it half of the mouse seems to be gone. I wasn't aware that snakes could bite off pieces. But he is in a deli cup and the other half is nowhere to be found. This is the second time he's done this but the first I fed him in the cage and figured i squeezed to hard picking it up removing it and cut the mouse with the tweezers, but this time i didn't use tweezers and same thing happened. My question is since hes only eating half of normal should i feed him twice as much?
