Temperature & Humidity

Aim for 29-32 C in the basking area and 22-25 C on the cool side, turning the heat off at night so the enclosure cools. Average humidity should be 50-70 percent, naturally dipping by day and rising at night. Mist as needed and line the cool hide with damp sphagnum moss to create a humid retreat.

Enclosure

Slender though it looks, this is an explorer, and the stated minimum for one adult is about 180 x 90 x 90 cm. Start juveniles in something small and move them up, to an enclosure at least 90 cm long and beyond. Use a soil-based substrate with clean leaf litter on top, which both holds humidity and gives the snake something to explore. Remove faeces and urates daily.

Diet & Feeding

It takes mainly rodents, along with birds and eggs. In captivity offer thawed frozen mice or rats sized to the snake. It is active both day and night, so feeding time is flexible. Leave it alone for a while after a meal to avoid regurgitation.

Temperament

When startled it freezes and wrinkles into kinks, and when cornered it either flees or vibrates its tail; researchers do not regard the tail vibration as rattlesnake mimicry. Keep it singly. Texas animals have a reputation for being feisty, so build up handling gradually.

Notes

It is not listed in the CITES appendices. It is neither a specified animal under the Appended Table of Japan's Act on Welfare and Management of Animals nor an invasive alien species under the Invasive Alien Species Act. The IUCN Red List assesses it as Least Concern. The name black rat snake is also used for Pantherophis alleghaniensis, a different species found east of the Mississippi, so confirm the scientific name Pantherophis obsoletus when buying.

7 things to know before welcoming a Texas Rat Snake

1. 1Space for a Large Snake

   Adults typically reach 107–183 cm, with record individuals reported at up to 218 cm. Provide a spacious, tall enclosure that lets it fully stretch out and move comfortably.

2. 2Color Changes With Age

   Hatchlings are gray with brown blotches, but as they mature they develop a glossy black coloration with white lips and throat. Texas specimens can show orange or reddish tones, adding visual variety as the snake grows.

3. 3Handle Gradually

   When startled it freezes and folds its body, and when cornered it flees quickly or vibrates its tail. Texas individuals can be known for a short temper, so don't rush into handling; get the snake used to you step by step. It is rated beginner-level to keep.

4. 4Secure Against Escapes

   Rat snakes are strong and can squeeze through surprisingly small gaps. Make sure the enclosure lid and latches are secure, with no openings it could push through.

5. 5Temperature and Humidity Control

   A gentle day-night temperature gradient, along with a warm basking spot and hiding places, helps it feel secure. Avoid extremes of dryness or humidity, adjusting as needed for the season and room conditions.

6. 6Care During Shedding

   As shedding approaches, the skin may look dull and the eyes can turn cloudy. Avoid handling during this period and keep humidity slightly elevated to help the shed go smoothly.

7. 7What to Prepare Before Adoption

   Have an appropriately sized enclosure, heating equipment, a thermometer/hygrometer, hides, and a water dish ready before bringing your snake home. Since it grows quite large, plan ahead for the extra space it will eventually need.
