Nearly all pet store anoles are WC. And it's not so much mites that you are worried about, it's intestinal parasites like worms. Plus, your snake does not need a treat. Feeding an anole to a snake already taking mice is like taking a step backwards. The anole is a baby corn's natural diet; it takes work to get them established on a safe (parasite-free) diet of mice, so you don't want to risk them losing the taste for mice in favor of anoles.
