Tibetan Dwarf Hamster

Overview

The Tibetan Dwarf Hamster (Cricetulus alticola) is a rodent in the hamster family. Body 8–11 cm. Found at altitudes up to about 5,000 m, making it one of the highest-living hamster species. Occupies alpine meadows, rocky hillsides and high-altitude steppe. Adapted to extreme cold and low oxygen pressure, with a relatively small body and dense fur for insulation, grayish-brown in color. Classified as Least Concern.

Scientific Name & Origin

Scientifically known as Cricetulus alticola, the Tibetan Dwarf Hamster belongs to the genus Cricetulus. It is a wild species not normally kept as a pet. Its native range covers Tibetan Plateau, Ladakh (India), Nepal.

Appearance & Size

Body 8–11 cm. Adapted to extreme cold and low oxygen pressure, with a relatively small body and dense fur for insulation, grayish-brown in color. Hamsters are distinguished by expandable cheek pouches used to carry food and nesting material, and by continuously growing incisors. Coat colouration and markings vary between species and individuals.

Behavior & Temperament

As with most hamsters, adults can be territorial toward one another and introductions should be supervised. Hamsters are generally crepuscular, most active at dawn and dusk, and spend much of the day resting in a burrow or nest.

Habitat & Ecology

In the wild this species inhabits Tibetan Plateau, Ladakh (India), Nepal. It lives in a burrow system that provides shelter from predators and temperature extremes and is used to store food. Like other hamsters it is primarily a seed and plant eater, supplemented by insects and other small invertebrates. As a prey species it is an important part of the food chain for owls, foxes, mustelids and snakes.

Health & Lifespan

Wild hamsters generally have short lives, often only one to three years, due to predation and harsh environmental conditions. In the wild, survival is shaped by predation, food availability, climate and disease. Continuous tooth growth and seasonal fattening or torpor are important aspects of their physiology.

Conservation Status

IUCN Red List status: Least Concern. It is currently assessed as Least Concern by the IUCN, thoughlike all wildlife it depends on the preservation of its native habitat. The species is native to Tibetan Plateau, Ladakh (India), Nepal.
