So an hour or so ago My BP Pooped out a half eaten rat, pretty self explanatory title. The smell was unlike anything I've ever smelled, extremely horrendous, However I know for sure it was not a regurgitation as there were brown solid poops and when i picked up the substrate and said poop with a plastic bag it all came out as one piece, his cloaca smelled the same too. I'm guessing its either cause my hot side of the enclosure is not hot enough or the meal was too big for him, worse case scenario being parasites. But as this is my first time keeping a BP I can't be entirely sure and I'd like some advice .

Here is a photo of the poop in question, however I must warn you it is pretty disgusting https://imgur.com/JGSDCRG
