Things You'll Need
- 2 to 3 cages
- Bathtub
Instructions
Place the new dwarf hamster in its own cage next to the cage of your resident hamster, where they can see and smell each other. Let them live and play separately for several days. Occasionally switch a bit of their bedding or toys. This gets the hamsters used to the smell and sight of each other.
Place both hamsters in the bathtub (empty of water, of course, and with the drain safely sealed). You can put down treats, paper towel rolls to tunnel in, and any other things that are fun for your hamster. The idea is to introduce them in neutral territory rather than in their living spaces. Carefully monitor their exchanges, and end the session if there is fighting or aggression. Repeat daily until the hamsters are interacting in a positive manner.
Move hamsters into a cage which neither one has ever inhabited. If that is not possible, thoroughly clean the cage you intend to let the hamsters live in. Change all food and bedding. The idea is to start their lives together in an enclosure where neither one's scent is dominant.
