We have a medium sized waterfall for our veiled chameleon Karma, but she deliberatly craps in it where ever its put in her enclosure. she seems fine and healthy but i want to make sure shes getting enough. Right now I spray her leaves probly more than i should and have a few hermitcrab drinking sponges hung around the top of the cage. but i wonder if shes getting enough water? or if theres another way she could get it easier? the sponges only stay wet for an hour or so.... plz help.
