There are a great number of reasons why your pet snake may regurgitate their meals soon after eating them. Some, but not all of them are named below. If for any reason you are not sure why the snake is vomiting you should seek the medical advice of a veterinarian qualified and trained in caring for reptiles. Not all vets know how to care for reptiles or are even willing to try.
1. Illness: Severe stomach and intestinal infections such as; parasitic, bacterial and viral infections all can cause regurgitation, and gastric ulcers can also cause a reptile to regurgitate after eating. Gastrointestinal obstructions can also occur if organs, such as the liver or kidney, become enlarged.
2. Stress: Too much noise, too many snakes in the same cage, or movement around the reptile or excessive handling after feeding can cause stress so severe that the reptile regurgitates. Snakes should be left undisturbed for several days after feeding so that it has time to properly digest its meal.
3. New Meal: over-eating or eating too fast from prolonged times between feeding.
4. Upset: handling a snake too soon after it has eaten or it sees another rat too soon after eating they will regurgitate to make room for the newly found exciting warm meal running around in their cage.
5. Food items too large. If a snake cannot easily swallow its prey because of the size being too big they will often regurgitate it. Next time feed a smaller rat.
6. Temperatures and humidity: The food, the snake or the environment being too cool. Snakes need to be kept warm and the temperature should be around 80 degrees. This sometimes happens because of feeding frozen rats.
7. Poisons: If a snake ingests a poisonous substance its body will automatically regurgitate it much like our bodies protect us by vomiting after being food poisoned.
8. Nervous snakes that lack a proper hiding area or box. If a snake cannot hide it might become more and more nervous and upset, stressing out to the point of regurgitation. Make sure your snakes habitat is set up correctly with everything he or she needs including a dark place to coil up and hide.
Keep your pets habitat clean and infection free. Wash bowl and replace with clean fresh water daily. If you use chemicals such as soaps or bleach in cleaning your pets water bowl be sure to get all residual compounds by washing the bowl with water thoroughly before refilling. Keep temperature at the correct degrees. Make sure the lid is on securely to keep your pet safe. Do not keep more than one snake in a cage at a time unless you are breeding them. They must be close to the same size or they may eat the little one. Always pay close attention to your pets health. First sign of illness you should seek medical attention to prevent the situation from getting worse.
Continued regurgitation is a symptom you should take serious. If your pet snake continues to regurgitate their meals you need to see the veterinarian as soon as possible so that he or she can examine the affected snake and start the healing process. The longer the regurgitation continues, the greater the risk of death from pneumonia or starvation.
