Purchased 2 Nigerian Uro's this saturday and they love the new cage i had ready for them. They did notice the underground tunnel system that I built for them and after exploring their new habitat they ventured into the tunnels and Dens i have for them. My question is how long will they stay in there? Its been 3 days and I have not seen them. I know they are becoming acclimated with their new enviornment but when should i be worried to the point were i have to check on them?
