So April 13th i got a spider ball python i liked him and he didn't look too skinny but i knew he needed to gain some weight he was feeding him live rat pups hes about 3 feet so i got a pack of three small rats.Well he hasn't eaten I've thawed it held it by its tail and shook it,heated up the mouse on it head than also on stomach,kept it in with him also used tongs and held it behind the rats head and moved it,shook it I've tried a lot but today he looks veryy skinny like scary thin if anyone can give me any ideas of what to do I'd definitely appreciate it its just when i hold him on top of my hand he just lays very flat i mean he does move but i don't know what to do.He hasn't really come out of his hiding log i saw him last night come out and look around but that's it
