prolapse???

Question
we have had our lepoard geko for about a month, we bought it from a private adds, she told us she was 6 months old, however in the last few days shes became really slow, listing to one side and chewing her foot, she also seems to have a prolapse anus, shes also not eatin unless we feed her????

Answer
Sounds like a neurological illness or injury, or perhaps impaction on substrate or improper prey, or an awful parasite infestation. Prolapses can be deadly if the tissue is not replaced by a qualified person in a timely fashion. If it is allowed to dry out, tissue will die, become perforated, or infected.   

There are several things this can be, but the certain thing is that she needs a vet or she will almost certainly die.
