It varies depending on their growth rate. They can shed almost constantly during a growth spurt when they are younger. As they get older the sheds become much less frequent and are often patchy. A tail shed one week, a hand shed the next etc. They can go for several months without signs of a shed as adults.
Mirage came out of brumation on April 26. He was doing great. On May 2 he started acting funny. We just redid his tank, and he keeps going into one of his hides. He just lays there. He shows no intrest in food. HELP!
