About 30mins ago I fed my BP for the first time. I know earlier I said I wasn't supposed to feed it until tomorrow but the pet store said they put the wrong date on the notes. Anyways, I fed him a small mouse slightly bigger than his grith (I believe it is called) and he struck and ate it immediately. Now he is already crawling around again and flicking his tongue. Is this a sign he is still hungry? Should I feed him another one or a bigger one or what?
