Interesting Reptiles"Lucy" is a magnificent 12.5-pound Leopard Tortoise. Her owner is an experienced keeper and takes excellent care of the tortosie. Lately Lucy was digging excessively in her enclosure and a radiograph revealed that she had produced 4 eggs. Tortoises, like chickens, can produce eggs in the absence of a male and Lucy did this last year around the same time (November) as well. We gave an injection of a hormone to induce labor and help her expel the eggs without surgery, which she did within 90 minutes of her visit. The radiograph was useful both to confirm the diagnosis and to know with certainty how many eggs to expect.
Improper bedding results in GI impaction in a bearded dragonThis poor lizard suffered bad advice from a pet store. His diet was unbalanced, leading to thin, soft, translucent bones on the radiograph (right). He also was kept on sand that was supposedly "digestible," and ate too much trying to correct his imbalance. This resulted in a colonic impaction (bright white on the radiograph). The owner read on the web that sand could be a problem when there was no stool for 2 weeks, so he switched to ground walnut shell bedding. The lizard ate that too, making the impaction worse (gray, lumpy material in between the black, air-filled lungs). The last photo shows what we were able to remove after several days of oral laxatives, hydration, and manual removal of the impaction: an impressive amount of sand, walnut shell and inflammatory membrane. Now we're working on the calcium deficiency that started the whole thing.
Egg binding in a parson's chameleonChameleons are difficult to care for in captivity but this keeper does an outstanding job. He has a greenhouse with UV-transmitting glass and raises 5 kinds of cockroaches and also walking sticks to feed his Chameleons. This beautiful lizard presented for not eating and a distended abdomen. Radiographs showed that she was full of eggs, visible as symmetrical, round opacities looking like clusters of grapes. Medical efforts to get her to lay the eggs by herself failed, and she had to undergo a sort of a lizard Caesarian section. The sedative caused her to temporarily turn a bright canary yellow like Tweety Bird. We removed 49 eggs, and she did well.
Snake shedding, retained eyecapsSnakes periodically shed their skin. When the old skin separated from the new skin underneath, lymph fluid collects in the cleavage zone between layers and makes the snake look dull or opaque. Snakes (and some geckos) lack eyelids and instead have a clear scale, the spectacle, which covers each eye like a goggle. Snakes are usually opaque for 5 to 7 days, after which they clear up for another 5 to 7 days before they actually shed.
Two-headed reptiles are really conjoined twinsReptiles with two heads often appear in the news as unusual freaks, but in reality they are fairly common. This defect happens when a fertilized egg begins to divide into two eggs, which normally would result in identical twins. In these cases, the division of the egg is incomplete so only the front half of the body is duplicated, while the back half remains single. Some conjoined twin reptiles have multiple birth defects and die shortly after birth, but many live full and normal lives. All of these examples were seen at Vernon Hills Animal Hospital, and all were doing well. In each case both heads eat.
