The Roborovski hamster ( Phodopus roborovskii) is extremely small and fast, making it difficult to keep as a pet. If housed together, acute and chronic stress might occur, [8] and they might fight fiercely, sometimes fatally. Effect of Exercise on Photoperiod-Regulated Hypothalamic Gene Expression and Peripheral Hormones in the Seasonal Dwarf Hamster Phodopus sungorus". One extinct hamster of Cricetus, for example, lived in North Africa during the Middle Miocene, but the only extant member of that genus is the European or common hamster of Eurasia. Russian hamsters (Campbell's and Djungarian) live about two to four years in captivity, and Chinese hamsters 2 + 1⁄ 2–3 years.

When examined, female hamsters have their anal and genital openings close together, whereas males have these two holes farther apart (the penis is usually withdrawn into the coat and thus appears as a hole or pink pimple).If captive female hamsters are left for extended periods (three weeks or more) with their litter, they may cannibalize the litter, so the litter must be removed by the time the young can feed and drink independently. Taxonomists generally disagree about the most appropriate placement of the subfamily Cricetinae within the superfamily Muroidea. Hamsters are more crepuscular than nocturnal and, in the wild, remain underground during the day to avoid being caught by predators. Hamsters tend to love peanut butter but it is important to feed it to them carefully because this sticky food can get stuck in their cheeks.

Hamsters are hindgut fermenters and often eat their own feces ( coprophagy) to recover nutrients digested in the hind-gut, but not absorbed.

The name "hamster" is a loanword from the German, which itself derives from earlier Middle High German hamastra. Other hamster species commonly kept as pets are the three species of dwarf hamster, Campbell's dwarf hamster ( Phodopus campbelli), the winter white dwarf hamster ( Phodopus sungorus) and the Roborovski hamster ( Phodopus roborovskii).They have thick, silky fur, which can be long or short, colored black, grey, honey, white, brown, yellow, red, or a mix, depending on the species.

Hamsters have scent glands on their flanks (and abdomens in Chinese and dwarf hamsters) which they rub against the surface beneath them, leaving a scent trail. conducted a molecular phylogenetic analysis of 12 of the above 17 species using DNA sequence from three genes: 12S rRNA, cytochrome b, and von Willebrand factor. Female Chinese and Syrian hamsters are known for being aggressive toward males if kept together for too long after mating. Wild hamsters will also appropriate tunnels made by other mammals; the Djungarian hamster, for instance, uses paths and burrows of the pika.The average litter size for Syrian hamsters is about seven pups, but can be as great as 24, which is the maximum number of pups that can be contained in the uterus. It may be hard for the babies to not rely on their mother for nursing during this time, so it is important that they are supplied with food to make the transition from nursing to eating on their own easier. The best-known species of hamster is the golden or Syrian hamster ( Mesocricetus auratus), which is the type most commonly kept as a pet. Although pet hamsters can survive on a diet of exclusively commercial hamster food, other items, such as vegetables, fruits, seeds, and nuts, can be given.
