How should the male and female Dwarf hamsters be introduced?

Their cages need to be in the same room. Getting to know each other’s smells will prevent possible fights. The introduction process is best to take slow, so leave the hamsters like that for about a week. The breeding process will be more comfortable since the Dwarf hamsters will already be familiar with their different smells. Too early of an introduction can cause hostility between the male and female hamsters.

Take a clump of their bedding and put it in the opposite cage after about one week. The Dwarf hamsters will become closer but still be at a distance. The Dwarf hamsters are ready to be able to see each other! Push their cages close together so they can meet face to face.

Have a neutral cage set up. The breeding process will occur here. The neutral cage will not be as stressful for the male and female Dwarf hamsters. There are no chances of stress because the pen is smell free! Like all enclosure, this should contain fresh water, food, bedding, and a hide house.

Can two or more Dwarf hamsters be kept in the same cage?

Make sure to clean out your female hamster’s cage before she becomes further along. Use paper towels, a brush with a pan, a safe cleaning solution, and a garbage bag. To prevent any bacteria from coming in contact with your skin, use rubber gloves.

Sweep the dirty bedding into the pan using the brush. Continue until there is no bedding left in the enclosure. Clean off debris from the sides of the cage. Use a vacuum to get into the tight spaces and corners.

Next, spray the cage down with your choice of a safe cleaning product. Get the spray on the bottom and sides of the cage. Wipe the wet pen down with a dry paper towel.

Put all of your Dwarf hamsters belonging in a sink to be washed. Take soapy water and rub the objects until its dirt free. The Dwarf hamster’s wheel will be especially dirty, so take extra time to clean it off. Rinse the accessories off when the washing is done. Towel dry the objects and set aside to air out.

Add paper-based bedding to the clean cage. There should be at least four inches of litter. Evenly distribute the bedding throughout your hamster’s cage.

Taking Care of the Litter

The babies are okay with their mother’s milk. The pups get everything they need from nursing. They may begin to explore outside the nest.

After about one week, check the health and development of the pup. Fur will begin to come out in the pups. The color will start to appear in their hair. Babies will start to explore outside of the home, but the mother or father hamster will scoop up the pup in their mouth and bring them back to the nest.

When should the next cage cleaning be?

Clean the cage two weeks after birth. Set up a safe area to put the mother and her pups. Use only water to clean out the enclosure. Keep the nest put together. Replace the bedding if it is soiled and wet.
