I wish I could buy one at a time but I don't have anyone nearby to purchase from. The local pet stores all have huge rats only.
When they do get too large - I do euthanize them to use as f/t down the road but it doesn't help my situation for the one snake that eats live to not have enough to get me through to the next show.
I've thought about breeding my own - but I don't think one live feeder would justify breeding my own.
