Max and I prekilled the rodents we bought today. It wasn't as bad as I imagined, and actually I think it was a better death than getting strangled by the snakes.
All snakes took the P/K food readily.
And, best of all, none of my babies were hurt.
Thanks for the suggestions you guys. BP.net is the best.
I see donations in your future from Max and I. You are all wonderful.
Thanks again!
