Such behavior is also common in many boids. Many animals arrive at the store already severely emaciated and dehydrated. Look for ticks and mites. These are often left untreated, with new, unaffected animals placed in the same tank as the parasite-laden animals. In many reptiles, when the mouth is very pale, or is a grayish-pink, the animal may be anemic.
Swollen eyes are an indication of infection or dietary problem.
Crooked backs and tails indicate a calcium deficiency. Rounded, firm thighs, whether or not accompanied by bumps in the tail, legs or swollen jaws, indicates advanced calcium deficiency. Flaccid or limp toes or limbs indicate possible fractures. Feces-streaked vents and swollen, distended bellies may be related to amoebic or parasitic infections, inadequate heat, substrate which has been ingested and become impacted, inappropriate food items or dehydration. These may be related to attacks by other animals or overcrowding during shipment or in the store.
