I live in the North West, and we DO have monster slugs. !2 inch banana slugs crossing the road everywhere. Ive been thinking of using these slugs and just using the younger ones after they breed. I suppose having a few different species could be beneficial to the snakes. There are so many slugs around here that I honestly dont need a colony, it would just be more convenient if I didnt have to go out and obtain so many slugs from somewhere other than my fridge :P I'm feeding an adult female ordinoides, she readily eats anything I give her (pinkies, safe fish, worms, slugs, snails, frogs/tadpoles). Her 3 remaining babies are feeding on fish and worms with a little calcium and multivitamin supplement right now.
