My question is how do you keep your snakes from knocking over the deli cups? Ive seen some of BHBs videos where they have like a built in cup holder and some of the new tubs even come with plastic water holders built right in... Does anyone use the deli cups without a holder to put them in? I use to use a ceramic bowl that I picked up from petco or someplace but I found out that it seems like a slimy film would form over the bottom of the bowl... I switched all my bowls to plastic dog bowls I got from Target and I have yet to run into the slimy film issue with these. I'm just curious as to how people who use deli cups with out a holder keep their snakes from spilling the water all over the tub.
