Russian Rat Snake

The Amur ratsnake (also known as Schrenck's rat snake) is a striking large colubrid native to East Asia, its black to blackish-brown body marked with pale yellow or white bands that split in two along the flanks. Adults can grow to about two meters, and their scales often carry a subtle blue sheen. The head is solid black on top, while the yellow upper lip scales edged in black add a distinctive touch. Generally calm and steady in temperament, this snake can grow comfortable with handling over time, but its large adult size calls for a spacious enclosure and some prior snake-keeping experience, making it a better fit for intermediate keepers than first-time reptile owners.

About Russian Rat Snake

A guide to the Amur ratsnake (Schrenck's rat snake), a large, strikingly patterned colubrid — covering its appearance, temperament, and care basics for intermediate reptile keepers.

7 things to know before welcoming a Russian Rat Snake

1Cage Space for a Large Adult
The Amur ratsnake can reach about two meters in length as an adult, making it one of the larger colubrids kept in captivity. Plan for a spacious, tall enclosure from the start so the snake has room to stretch out and move comfortably as it grows.
2Temperature and Humidity
This species comes from a continental climate, so its enclosure is best kept away from extreme heat and humidity, with a gentle temperature gradient it can move along. Watch the snake's behavior through seasonal changes and adjust conditions gradually rather than making sudden shifts.
3A Glossy, Striking Pattern
Adults show a striking pattern of pale yellow or white diagonal bands, each splitting in two along the flanks, set against a black to blackish-brown body. The top of the head is solid black, the upper lip scales are yellow outlined in black, and the whole body often carries a subtle bluish sheen.
4Temperament and Handling
Individual temperament varies, but many keepers find this species relatively calm for such a large colubrid. Because it grows quite large, handling is best introduced gradually in a calm setting rather than rushed.
5Shedding and Health Checks
Shedding is a good moment to check on overall condition — look for any retained skin patches or issues with the eye caps. Keeping a habit of watching appetite and waste output helps you notice any change from the snake's normal pattern early.
6Feeding Size and Frequency
Because this species grows so large, prey size needs to be matched to its current growth stage and build. Base feeding frequency on the individual's appetite and weight gain rather than a fixed schedule.
7Setup to Prepare Before Bringing One Home
Since adults can reach around two meters, it pays to set up a cage, heating equipment, and secure, escape-proof fittings sized for its eventual adult length before bringing one home. As this is considered a species better suited to keepers with some prior experience, it helps to build up basic snake-care knowledge first.
