What feeders do you find are better for your snakes? We now have 10 snakes 8 bps and 2 rtbs. Most are on rats, and one will only take white mice. I'm planing to start a small breeding colony of mice for my one girl, but I'm undecided if I want to breed rats or asfs for the rest. What do you find are pros and cons to breeding/feeding out rats and asfs?
