Sounds wonderful! We have one female BP here that from the time she was a baby has been very, extremely, absolutely prey size specific. She'd drive me nuts if I wasn't so lucky to have a rat colony handy so I can pick through the litters to get the exact size Miss Picky wants. I swear if the rat is a few grams either way she won't eat...put in the rat that's the absolute perfect size and she will. Glad you found what's working for Abbath.
