I've used slugs in the past. I reared some baby Dekays snakes (Storeria dekayii) on tiny slugs the size of match heads, it worked out well. I've fed them to Garters and to Slow Worms (Anguis fragilis) too. The preferred type seem to be those little beige coloured ones...no idea of a latin name, or common name for that matter! I didn't know you could buy such things from a shop though.
