Basics of Snake Nutrition

Snakes are carnivorous animals and their diets consist primarily of rodents and other small mammals like lizards, frogs, and birds. In captivity, they typically consume pre-killed mice or rats that have been frozen and thawed prior to feeding. In order for a snake’s diet to be nutritionally complete, it must receive all essential vitamins and minerals on a regular basis. These include vitamins A, D3 (calciferol), E (tocopherol), K (menadione), B1 (thiamine), B2 (riboflavin), B6 (pyridoxine), B12 (cyanocobalamin), folic acid, pantothenic acid, niacin, choline, calcium, phosphorus, magnesium, sulfur, sodium chloride iodine, bromide, and selenium. Additionally, certain species may need vitamin C supplementation if kept in captivity for long periods of time due to their lack of natural prey items.

Nutritional Deficiencies That Lead To Gaping

Inadequate levels of any one or more essential vitamins or minerals can result in various symptoms including gaping. Common deficiencies that lead to gaping include low levels of Vitamin A, Calcium & Phosphorous ratios being out of balance, vitamin D deficiency due to inadequate exposure to UVB lighting when kept indoors, magnesium deficiency due to improperly formulated rodent diets, and inadequately balanced supplements containing too much calcium or phosphorus relative to the other nutrients needed by the snake’s body. Poor nutrition can also cause weight loss which can then reduce muscle mass leading to lethargy as well as respiratory issues in some species which can contribute to gasping behavior.

Gaping is often caused by nutritional deficiencies in snakes. To keep your pet healthy it is essential that you provide them with a balanced diet containing all essential vitamins and minerals on a regular basis as well as appropriate access to ultraviolet lighting when kept indoors. If your snake begins showing signs of gaping it could be indicative of vitamin or mineral imbalances so it is important that you take them to see an exotic veterinarian right away for further evaluation and treatment options if necessary.


Understanding why your snake may be keeping its mouth open is important so that you can take steps to address any underlying issues. If you are ever concerned about your pet’s health or well-being, it is always best to seek help from a qualified veterinarian or reptile expert.
