If you feel that you are keeping on top of cleaning your hamster’s cage, but your hamster still smells, you may need to take a trip to your vet.

This way, your vet can ensure there is no medical reason for the smell, as an unusual or unpleasant smell could indicate an underlying health issue.

You could also look at your hamster’s diet [2] as some foods can cause unusual smells, and therefore you may be able to improve the scent that your hamster is giving off if you change his diet.

Look out for days where your hamster smells particularly bad, and then note down what you have fed your hamster previously.

Should I Bathe My Hamster If They Smell?

You should never bathe your hamster in water.

Hamsters are not attracted to water, and water is just likely to aggravate a hamster and can make them very ill as it weakens their immune system, which leaves them vulnerable to illnesses.

Hamsters clean themselves by grooming themselves, but it is possible for waste sometimes to get stuck in their fur.

If this happens, you can use a pet-friendly waterless shampoo with a soft cloth to wipe where your hamster cannot clean themselves. Be very careful not to get the shampoo near your hamster’s mouth or eyes.

You can also give your hamster a sand or dust bath. There are sand and dust that are specially made for hamsters.

It works by removing excess moisture, dirt, and oils from their fur cut.

When animals such as hamsters roll around in the sand or the dust, it absorbs any dirt or oil from the animal’s fur and helps to keep the fur healthy.

Some hamsters are known to enjoy playing in the sand, so cleaning the hamster also becomes an active source of entertainment.

In general, a sand bath is recommended over a dust bath, as a dust bath may cause respiratory issues for some hamsters.

How to Train Your Hamster to Use a Litter Tray

Hamsters are easy to toilet train and will use a litter tray if it’s put in place. Hamsters prefer to put their litter in one place.

If you decide to litter train your hamster, you will first need to ensure you’ve got all the equipment you’ll need.

First of all, you’ll need to find a litter tray when it comes to finding a litter tray for your hamster. Your local pet store or online pet stores should have a litter tray.

There are plenty of litter trays to choose from, and they are relatively inexpensive.

Some litter boxes tend to be covered, which means the smell will stay within the box. Another option is a litter pan with high corners, and these work as well as the others.

Once you have selected your litter tray, you will need to consider what kind of litter to get. If you struggle to find hamster litter, then look for cat clumping litter, which is scent-free and dust-free. Avoid litter that contains silica dust.

There are other options to choose from when it comes to litter. You can select litter made from grass, paper, grain, or wood. These are also a good option, and they can help control smells, as they are very absorbent.

If your hamster likes to fill his cheeks with the litter you have chosen, you will need to change to a different type of litter as some litter can scratch your hamster’s cheek pouches.

You are now ready to toilet train your hamster, and your next job is to locate the corner that your hamster already goes to the bathroom and place the litter tray in that corner.

If you decide to put the litter tray in an area you prefer, your hamster will ignore it and go to the bathroom where he chooses.

Pour some glitter into the tray so that the bottom of the tray is covered. Now add some of your hamster’s soiled bedding to the litter.

Place your hamster in his new litter tray, so he has the opportunity to sniff around and explore his new toilet.

Never force your hamster into his litter tray, as this may put him off and may result in him biting you in return. Your hamster will soon work it out for himself once he has had time to explore his new litter tray.

If your hamster is using his litter tray as a place to eat or hide his food, then it could be that his cage is too small. That’s why he’s looking for a new area to place his food.

If your hamster is using his litter tray as a bed, it may be that he doesn’t like where he’s sleeping at the moment, or he doesn’t have a sleeping area.
