Giving him a bath with some mild/unscented soap like dr bronner's baby mild should help with the smell. I usually give Darwin a wipe after he goes (just with some paper towel) and then a quick spray with some Vetericyn and that works well.
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!
