Alright, I found a snail farm that raises snails for pets. I've purchased 4 adult Helix aspersa snails. They are the largest land snails in the USA. I will be offering them as treats to my frog and monitor lizard in a few months.

Has anyone fed their African bullfrog snails? I don't know how mine will respond to one. I know my monitor lizard will gobble anything that moves and has enjoyed slugs in the past.
