Recently my female Veiled Cham has started to dig holes some are almost tunnel like. She isn't to hot (or to cold) average temp is around 80 to 85. I added extra deep players for her to dig but Im slightly worried as she cant be pregnant (there is no male around). When I try to pick her up from digging she gets pissed (normally she didn't mind it), Any suggestion what made her change in to this odd behavior?
