Sorry Brian, that sucks man. Hindsight is 20/20 I guess.
I use the deli-cup with the hole in the top. I can't believe they sell ones with pre-cut holes??!! Are you serious? It takes like 4 seconds to cut out a hole, ha ha! Oh well, probably looks neater than mine.
All my Pythons and Colubrids get water dishes with the "holy lids". When I was using aspen, water would spill out of the dishes and get the aspen wet, which would mold-up in like 5 hours. So I started using the lids. I never went back. But you do HAVE to use an appropriate-sized deli-cup with an APPROPRIATE-sized hole cut out. This eliminates the danger.
