So Coda has been showing receptive colors, we have a laybin and a sheet to go around the bottom portion of her cage. How do I keep the sand at the right moisture so the hole doesn't collapse? we got the right consistency at first but how do I maintain it? As for the sheet when should I put it on? I know that they shouldn't see you see them digging but how do I know when its time? Last one, will her colors stay the same after shes done laying or will she go back to normal? Thanks!
