I feed my Uroplatus pietschmanni snails often at least during the warmer months. I live in Washington State and it gets fairly cold up here during the winter but if you are from a warmer area you can most likely find them year round. Only the females seem to like them though. Never had a male that was interested but the females absolutly love them. Make sure you get them from an area where pesticides are not used.

Here a shot sequence of one of my females eating a snail.
