The jury is still out on that. I have talked to one breeder who stated that polycarbonate cages (faunarium, critter keepers, and so on) kill baby red-eyes. I know of no scientific data to back-up that claim.
Then I talked to Michael Novy and he said that's BS, and that he uses them all the time with no problem. Still I feel safer glass, because I know that is inert.
