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their anal and genital openings close together, whereas males have these two holes farther apart (the penis is usually withdrawn into the coat and thus appears as a hole or pink pimple). in) long; the largest is the European hamster ( Cricetus cricetus), measuring up to 34 cm (13 in) long, not including a short tail of up to 6 cm (2.

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.

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. Testimony from Grant C Riddle (born 1929, living in Lake Wildwood, CA) who had a pet hamster in 1942. All hamsters are excellent diggers, constructing burrows with one or more entrances, with galleries connected to chambers for nesting, food storage, and other activities. Their eyesight leads to them not having a good sense of distance or knowing where they are, but that does not stop them from climbing in (and sometimes out of) their cages or from being adventurous. The best-known species of hamster is the golden or Syrian hamster ( Mesocricetus auratus), which is the type most commonly kept as a pet.Female Chinese and Syrian hamsters are known for being aggressive toward males if kept together for too long after mating.

They tend to learn similar noises and begin to know the sound of their food and even their owner's voice. 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. The breeding season is from April to October in the Northern Hemisphere, with two to five litters of one to 13 young being born after a gestation period of 16 to 23 days.

Female hamsters are also particularly sensitive to disturbances while giving birth, and may even eat their own young if they think they are in danger, although sometimes they are just carrying the pups in their cheek pouches. One rodent characteristic that can be highly visible in hamsters is their sharp incisors; they have an upper pair and lower pair which grow continuously throughout life, so must be regularly worn down.
