I'll look for hoppers at PetCo -- I wish you could see inside the bags of frozen mice they sell, but I will buy some regardless and try her on them next Friday when I feed her. I am SO scared she is going to choke but everyone has told me she can go a size up.
I am absolutely certain that Ruby has been underfed but sadly you can't help what you get with a rescue. I suspect (hope) that she will start gaining when she gets fed hoppers in the future. She really is healthy enough otherwise!
Dolly, I am sad to say goodbye also, but I don't "need" two snakes (not that many people don't have half a dozen!) I am seriously considering a turtle adoption to further my "herp" educational programs, and then I
really wouldn't have room for her. Believe me, I vetted her new adoptee VERY carefully and his tank setups are out of this world. She will be well taken-care of!
