Quoting Loka Lokita:" I'll try a Sprite maybe...he's always REALLY active. It's not like him to have not moved in over an hour."
mine was like that too and id get really paranoid when he was being quiet. But all was fine with me. He was just taking a very rare nap...which as it turned out he didnt take that many naps when he got here!
by all means, call your dr or go into er if your that concerned.
