I had Humperdink on and off for the past 15 years and she was always na eater. About 2 yrs ago she stopped eating. I did all I could to get her healthy including shots and a new tank but still I was always taking the rats back, luckily they took them back. Then in November the original owner snake-napped her for 6 months and she still hadn't eatin' much. Then in April I got her back and at first she had a bad shed but she started eating. Now she takes down live large rats weekly and is doing great. I'm still waiting for her to shed again and I keep her in perfect temps and humidity as well.
It's amazing how she has recovered and I think it is because she has realized how good she has it in my care.
