Exposing plastics to heat causes them to break down faster and release toxins. If you must use them in the viv, try to get ones that say BPA-free (although I was told recently that there are other synthetic estrogens besides BPA in plastic---still checking on that). Always wash new plastics with soap and water before using to wash off toxins that remain after the manufacturing process.
I especially avoid PVC in vivs b/c it is not good for the frogs (referenced from Poison frogs: Biology, Species and Captive Husbandry).

I don't see a problem with it, if anything smooth the cut edges enough to prevent any sharp spikes, they should be fine if it's relatively clear cut.


Not to get side-tracked, but can you elaborate on this a bit? I don't have the book so I can't look in it, but I never imagined a problem with PVC. People use PVC all the time in reefs and I've used it with darts before, so if you have any information that I'm missing I would be interested to hear it.
Thanks,

PVC may or may not cause visible issues linked to its use through our casual observation in frog or fish tanks, but it is toxic stuff. The subtle, unseen issues involving cellular damage are what is concerning. It's not a good thing that they use it in our homes for our water supply and in shower curtains. Here's a basic link. I'm sure you could Google some more results that point to studies on it.
