So I've fed my snake 2 times already and I haven't been able to find any evidence of waste in the tank. Tonight I was holding him and he started to go (yuck) and I put him back in his tank. The thing was that his excrement looked very liquified and runny. I'm assuming I haven't found any more because its also been liquid. So I have to ask: is this a bad thing? I haven't noticed any bad smell or anything but I'm worried about the state of his waste.
