Mandarin Rat Snake

Mandarin Rat Snake key facts

Care level

Intermediate

Lifespan

Typically 10-15 years

Size

Up to 1.4m total length

Temperature

16〜27℃

Diet

Carnivorous, mainly small rodents

Temperature & Humidity

It likes cooler conditions than most colubrids. A gradient of 16-27 C is workable, but steady temperatures around 24 C are considered ideal. It tolerates cold far better than heat, so keep the enclosure from ever exceeding 29 C; managing summer heat is the key to keeping it.

Enclosure

A 40-gallon equivalent, roughly 90 x 45 x 45 cm, is large enough for an adult. It is secretive and uses rodent burrows in the wild, so place snug-fitting hides on both the warm and cool sides. Substrate it can burrow into helps it settle. Site the enclosure somewhere cool where overheating can be avoided.

Diet & Feeding

It feeds mainly on small rodents. In captivity offer frozen-thawed mice sized to the snake, and because it is a small rat snake avoid increasing prey size too far. Being crepuscular, it responds better when fed around dawn and dusk.

Temperament

Secretive, spending much of its time in cover. It is generally placid but often out of sight, so if you want to see it, combine burrowable substrate with a hide you can look into. Snakes can prey on one another, so keep it singly.

Notes

Not listed on any CITES appendix. The IUCN assesses it as Least Concern. It appears neither on the schedule of designated dangerous animals under the Order for Enforcement of the Act on Welfare and Management of Animals nor on Japan's list of invasive alien species. The old name Elaphe mandarina is still in circulation, so confirm that it refers to the same animal when buying. It is heat-sensitive, so do not keep it where summer room temperatures cannot be controlled.

About Mandarin Rat Snake

The Mandarin Rat Snake is a mid-sized colubrid with striking black-and-yellow diamond markings, growing to at most 1.4m. Secretive by nature, it suits intermediate keepers and typically lives 10 to 15 years.

7 things to know before welcoming a Mandarin Rat Snake

1. 1Always Provide Hides

   Mandarin rat snakes are naturally secretive and won't settle without shelters or tunnel-like hides. Since they favor tight, dark spaces reminiscent of rodent burrows, include several hiding spots throughout the enclosure.

2. 2Manage a Temperature Gradient

   As ectotherms, they need a gradient inside the enclosure with a warmer area and a cooler zone. Proper temperature control supports healthy digestion and normal activity patterns.

3. 3Enclosure Sized for 1.4m

   Adults stay under 1.4 meters, making this a relatively compact species, but the enclosure should still let the snake stretch out fully. Being smaller than many other rat snakes, it's easier to house than larger species.

4. 4Secure Against Escapes

   Like most snakes, they can slip through surprisingly small gaps, so choose an enclosure with a tight-fitting, lockable lid. Juveniles are especially slender and can escape through the smallest openings.

5. 5Feeding Size and Frequency

   Frozen-thawed mice are the typical diet. Adjust prey size and feeding frequency to the snake's growth stage to avoid digestive issues.

6. 6Why It Suits Intermediates

   While hardy and generally easy to handle, its secretive habits and specific temperature and humidity needs call for some prior knowledge. It's best suited to keepers with basic reptile-keeping experience.

7. 7Plan for the Long Term

   With a lifespan of roughly 10 to 15 years, keeping one is a decade-plus commitment. Consider upcoming life changes, such as moves or family plans, before bringing one home.
