awesome question...mine poops around two to three days after feeding. Although I can still see the hopper being digested, I'm guessing its from the previous feeding. The first poop I had with my BP was interesting. He and I were watching TV together and I feel my shirt getting wet and I'm like oh damn...here he goes. But one thing, be sure to watch for urates (little white things that come during the 'poop' process) it's completely normal. Just a little heads up. Happy watching!
