Campbell's Dwarf Hamster Behavior and Temperament

Dwarf Campbell's hamsters make peaceful, low-maintenance pets. They prefer to dig, tunnel, and explore when they are awake. Although they prefer the night, they occasionally become active during the day. The majority are amiable and don't mind being handled, especially if you begin doing it gently while they are young. But if they feel threatened, certain animals may nip. Additionally, because they move so quickly and are so little, they might be difficult to control.

Although they won't form bonds with humans the way a cat or dog would, many of these hamsters will approach the edge of their enclosure if you approach them. The Campbell's dwarf hamster is sociable with other members of its species, unlike some other hamster species. They should preferably be introduced to one another from an early age and kept in same-sex couples or small groups. However, keep an eye out for any signs of violence since they have a tendency to become territorial. Additionally, it is important to keep them separate from other household pets, including other hamster species, due to their small size and fragility.

There are two primary types of enclosures: a wire cage with a plastic foundation or a glass/plastic aquarium with a safe mesh top for ventilation. If you choose a wire cage, make sure the bars are close enough so that the hamster cannot fit between them because they have a penchant for breaking out of their cages.

Include a nest or other hiding place for your hamster inside of the enclosure. To avoid any damage, including chew toys and an exercise wheel with a smooth surface (not wire).

For your pet to explore, you may also install hamster tunnels and storage spaces. However, be careful that they don't use too much room, especially if the cage is home to several hamsters. Fighting or territorial behavior may be more likely in confined areas.

Specific Substrate Needs

A 1- to 2-inch layer of bedding, such as aspen wood shavings or unscented natural cellulose fibers, should be placed at the bottom of the cage.
