This is the largest domesticated species. They are strictly solitary, generally have a calm temperament and require a spacious habitat. It’s important to note that even though they are the most common species found in pet stores, we do not encourage purchasing from pet stores, as these establishments source most of their animals from mass‑breeding facilities where breeding and housing conditions are often far below recommended welfare standards.

The Russian dwarf hamster, often called the Winter White, is one of the five domesticated hamster species. They are appreciated for their generally gentle temperament and their unique ability to change color during the winter. Pure‑line Winter Whites are very rare in North America, as most hamsters sold in pet stores are hybrids (Campbell x Winter White).

Winter Whites have a particular metabolism and, like all dwarf hamsters, may be predisposed to diabetes. It is therefore important to:

• choose a diet specifically suited for dwarf species,
• limit sugary fruits,
• offer high‑quality animal protein,
• provide a variety of unprocessed seeds.

Often mistaken for the Winter White Russian hamster, the Campbell’s dwarf hamster has its own distinct physical, behavioral and genetic characteristics. They are a lively, curious, and very active species, but one that requires particular attention due to their predisposition to diabetes and obesity. They originate from the steppes and grasslands of Central Asia, particularly Mongolia, Russia, and northern China.

The Roborovski hamster, often nicknamed ‘Robo,’ is the smallest domesticated hamster species. Known for their impressive speed, shy temperament, and very active behavior, they are primarily an observation animal rather than one meant for frequent handling. Despite their tiny size, they have significant environmental needs and a lifestyle that differs from other species.

Roborovskis have a compact body shape, quick little legs, a rounded snout, and characteristic white ‘eyebrows’ that give them a lively, curious expression. They are not recommended for young children or for people looking for a hamster they can handle regularly. This is a species that thrives when allowed to live their life freely, exploring, digging and running.

Like all hamster species, the Roborovski must be housed alone in captivity. Attempts at cohabitation almost always lead to conflict, even though some myths persist. Robos love sand baths, which they use to clean themselves, play, and reduce stress. A large sand area is highly recommended.

The Chinese hamster is one of the five domesticated hamster species, but also one of the rarest in captivity, especially in Québec. Often mistaken for a dwarf hamster, they are not one: they belong to a different genus, have a distinct body shape, and display behaviors that clearly set them apart from other species.

Chinese hamsters originate from the mountainous and semi‑desert regions of China and Mongolia, where they adapted to dry, rocky environments.

As adults, they generally measure between 10 and 12 cm, making them longer and slimmer than dwarf species. Their weight usually ranges from 30 to 45 g. In captivity, their average lifespan is between 2 and 3 years. Chinese hamsters are easy to recognize thanks to their elongated body and their tail, which is noticeably longer than that of other hamster species.
