I've had my 2-3 month old pacman frog for roughly a month and they tend to spend a majority of their time burrowed, only coming out to eat. They haven't refused a meal from me but I haven't actually seen any poop in their enclosure yet. I'm not sure if maybe they already pooped while burrowed and I can't tell? I have them soaking in their water dish to encourage it but they still haven't passed anything.
