Is it possible to over-clean? I don't know if this can be detrimental to a snake's health - like weakening it's immune system by lack of exposure. I spot clean, and then take everything out every two weeks and clean it with chlorhexidine, which I order whole-sale from the vet that I work for. It pretty much kills anything, and every time I refill his water bowl, I spray it down first. Could this just be increasing his susceptibility to infection? I haven't seen anyone say that they clean this often, but when I was doing my initial research, everything I read said that snakes can be extremely susceptible to secondary bacterial infections, and I was just trying to prevent that.
