Concerned :(

My 1064g pied girl usually only poops once a month but when she does, I swear for a second she gave birth to a brown snake :P Don't worry, they poop when they poop. If you start to notice a "sausage butt", then you can plan for a present soon.

If you are really concerned I recommend giving his enclosure a thorough clean. Make sure that when you put new substrate in, you take the time to ensure that it is all laid out neatly and get the enclosure looking just right. Put him back in the enclosure and walk away.

Wait 10 minitues. Go back into the room where he is and I GUARANTEE there will be poop everywhere.
