I checked my little guy this morning (I'm avoiding giving him a name until I confirm if he is indeed a he) and his paper towel was completely soaked with what I assume was urine. I'm pretty sure it wasn't a water spill, as it was all yellow. There was also a rather sizable lump in the middle of the tub, though I don't know if it was poop, urates, or both. It was about half white. This is my first snake so this is my first experience with snake excrement, and I'm not sure yet what is normal. He just ate 4 days ago, so I don't know if that's too soon for a poop.
