Texas Rat Snakes

Texas Rat Snakes are common snakes kept as pets. My favorite being the Leucistic Texas rat snake.  Despite their beauty, they generally have a pretty nasty disposition to them, although I have heard of people having tame individuals.

Locality: Texas Rat Snakes can be found in North America; mainly in Texas as their name implies.

Size: Texas Rat snakes are between 9-11 inches as hatchlings and can reach lengths up to 6 feet. Females tend to be larger than the males.

Lifespan: Rat Snakes can live up to 20 years in captivity.

Caging: Hatchlings can be kept in plastic shoe-box containers with holes drilled into the sides for adequate air ventilation. I prefer plastic tubs for caging over the commonly seen glass aquariums. Glass does not work well at holding heat and those screen lids that are used for them can make it a nightmare to keep constant humidity levels for subspecies that have strict humidity requirements. Rat Snakes should be housed separately unless being bred, Not because of problems with cannibalism as in King Snakes but because I do not believe that any two snakes should be housed together permanently.  A hide should be provided on both sides of the cage to allow the snake to feel secure whether it wants to be on the warm or cool side. (Rat Snakes like all snakes are escape artists and should always be provided with an escape proof enclosure).

Heating: A hot spot of 84-86 degrees should be provided along with a cool side in the mid 70's. A thermostat or rheostat should always be used to control the heating device. If using heat pads plugged directly into the outlet, they can reach temperatures in excess of 120 degrees which is WAY too hot for your snake and which can lead to burns or even worse. A thermal gradient should be provided allowing the snake to escape the high temperature and reside in a cooler temperature if it wants to.

Substrate: I prefer using newspaper or paper towels as substrate for multiple reasons. As they are not the most pleasant to look at, it does make cleaning much easier, Is very cost effective and most importantly, sanitary. Many like to use aspen which is fine but cedar bedding should NEVER be used for your snakes as it is toxic to them.

Feeding: Rat snakes are constrictors and generally have a strong feeding response. As hatchlings Texas Rat Snakes should be fed pinky mice once a week. As they grow, so should their food items. The best way to determine what size prey your snake should be eating is by feeding items that are slightly larger than the girth of the snake's body. Feeding live rodents is never a good idea. Live rodents carry parasites and can injure or, worse, kill your snake. Either Frozen thawed rodents or pre-killed rodents are preferred. Freezing rodents will kill any parasites that may have been living on the rodent and obviously eliminates the chances of the rodent hurting your snake. Fresh water should always be available for drinking.

Handling: Rat Snakes tend to be very active snakes. They can be very squirmy as hatchlings but with regular handling they will usually calm down nicely. Always allow at least 48 hours after feeding before handling your snake. This 48 hours is crucial for digestion. Handling within this time can cause the snake to regurgitate its meal which can lead to chronic regurgitation and can prove to be a very stressful ordeal for both the keeper and the animal.
