Burns may heal, but the skin may, from then on, always be sensitive to bottom heat. Feces on skin and claws indicate an unsanitary environment and probably a weak and sick animal. Feces on the back of a reptile may indicate a very sick one who is too weak to get out from under stronger cagemates. Abscesses, cysts, and broken bones require veterinary care and treatment. Deep recesses indicate a starved chelonian.
Soft shells indicate metabolic bone disease.
If the enclosure is not too hot for the species, and it is not a lizard giving an open-mouth threat, it is a sign of a respiratory infection. Indicates probably metabolic bone disease. Indicates systemic infection and abscesses. Could indicate respiratory infection, hypothermia, or, in less frequent cases, vitamin A deficiency. Weakness or shakiness indicates a severely debilitated or sick reptile.
