Tap water is normally fine for snakes, unless your's is heavily treated...do you taste chemicals in it? Do NOT use distilled water for snakes ever. Bottled is ok, though many times bottled water just came from someone's tap, & bottle water has often been shown to contain tiny bits of plastic from the bottling process- it won't matter as much to us, but we're a lot bigger than a snake. I use tap water...
I raise my own mice too, but I'm not sure what you're asking on that...![]()
