I'm confused. Do you mean "pooping" on you? Also, what is the container? Looks like water. If so, that is not a good idea. A feeder trough is fine, but you need to be real careful with leaving standing water. Most Chams do not recognize standing water as a water source, but they also said a cham can't be trained to use a rodent water bottle also. Mine did.
That's her food bowl, she gets sprayed 3 times a day & had a dripper on till lights out. She love eating out of her bowl, & I also throw sum free range In with her too. Yeah she poop on me the last 3 times I have got her out?? Not sure why?
