Has she pulled it inside her again or is it still showing? I had a female that essentially prolapsed her innards which I fed off to my adult. It looked like she blew a lumpy bubble out of her bum and was different from what you're seeing though.

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!
