How to Clean a Smelly Mouse

Mice are very clean pets. In fact, unless they're old or sick, they self-clean. However, mice can still get very stinky, which can result from a dirty living environment. If your mouse is smelly, you can wash it directly with washcloths and clean its cage and surroundings. You'll have a clean, non-smelly mouse in no time!

1
Dampen a washcloth with warm water. Submerge your washcloth in warm water. Make sure the water is temperate, not too hot or cold. Wring out any excess water, so that the washcloth is not dripping.^{[1]XResearch source}
- Mice do not like water, so make sure the washcloth is not too soaked! It should be damp.^{[2]XResearch source}
- Be careful to not make the water hot or cold, as either end can upset a mouse’s skin if directly applied.
- Choose the softest washcloth available to you.
2
Rub the mouse with the damp washcloth. Rub the washcloth over and slightly under the mouse’s fur. Make sure to rub over the entirety of the mouse. Continue gently rubbing until the unpleasant smell is gone.^{[3]XResearch source}
- Do not forget to clean the feet! The feet can trap a lot of icky waste, which can contribute to the mouse’s smelliness.
- Be careful of the mouse’s eyes, nose, and ears. These are especially delicate areas.^{[4]XResearch source}

Rub the mouse with water and puppy shampoo for an even deeper clean. If water alone could not get rid of that pesky smell, you can use a gentle puppy shampoo to help.^{[5]XResearch source} Use a washcloth to softly rub over and under the mouse’s fur. Continue this action until the smell is gone.
- Do not apply puppy shampoo directly to the mouse. Add the shampoo to water, which you can then dip your washcloth into. Ring out any excess.^{[6]XResearch source}
- Use a tiny amount of puppy shampoo. You will not need more than a few drops.^{[7]XResearch source}
- If the smell is not going away, it is likely that your mouse has a health issue. Take it to a veterinarian to get examined.^{[8]XResearch source}

Wash off the mouse with a damp washcloth. This needs to be done immediately after you finish shampooing the mouse. Take a wet washcloth and rub it on the mouse’s fur until the shampoo is gone.^{[9]XResearch source}
- Do not use hot or cold water. It should be warm.
- Ring out any excess water before applying the washcloth to the mouse.
5
Rub the mouse with a dry washcloth. Rub and pat the mouse lightly. Make sure to dry all areas of the mouse. Continue this until the mouse is completely dry.^{[10]XResearch source}
- Use a soft washcloth, as a harsh one can hurt the mouse.
- Do not air-dry or blow-dry the mouse. Air-drying keeps the mouse wet for longer and blow-drying can hurt a mouse’s ears.^{[11]XResearch source}

The mouse should be out of the way while you are cleaning. Safely place it in an enclosed location, where it cannot run away. Remember to periodically check on the mouse to make that it is comfortable and has not escaped.
2
Remove bedding and litter from the mouse cage. Discard all bedding to make sure you remove all the mouse’s waste. Do this every week, as a buildup of mouse waste and old food is unsanitary, can lead to bacteria growth, and can make a mouse smelly.^{[12]XResearch source}
- For daily cleaning, you can just remove wet or soiled areas.^{[13]XResearch source}
3
Disinfect and wash the mouse cage. Use a non-toxic cage cleaner and deodorizer to spray the entirety of the cage. Then, use a washcloth or paper towel to wipe up excess cleaner. Rinse thoroughly with water and dry well.^{[14]XResearch source}
- You can get disinfectant at your local pet store, grocery store, or online.
- If you cannot get disinfectant, you can use a water-soap mixture as a temporary substitute.^{[15]XResearch source}
- Make sure you dry the cage completely. A damp cage will add unwanted moisture to the new bedding.^{[16]XResearch source}
4
Disinfect and wash all toys and accessories. Just like the cage, spray all surfaces of the wheel, den, climbing wall, etc. Wipe the excess cleaner off with a washcloth or paper towel. To finish, rinse all items thoroughly with water and dry them completely.
- If the manufacturer of the toys or accessories gives specific cleaning instructions, follow them.^{[17]XResearch source}
5
Add clean bedding to the cage. You can use either recycled paper pellets or wood shavings. Take the bedding and completely cover the bottom of the cage. Continue filling until the layer of bedding is around one inch thick.^{[18]XResearch source}
- Do not use pine or cedar wood shavings. They can release fumes that can make your mouse ill.^{[19]XResearch source}
- You can add shredded paper towels or straw to the bedding. These are soft materials that can also be used by your mouse to make a comfy nest.
- Do not put newspaper in the mouse’s cage because the ink can rub off.^{[20]XResearch source}
6
Put back all toys, accessories, and dishes. Now that everything is clean, place all your mouse’s items back. Try to put them in the same place they were in when you removed them. Do not forget to fill the water and food bowl before adding them back!
- Once you've done this, you can put your mouse back in its fresh, clean home!

Mice are quite small and sensitive. Water upsets them and getting shampoo in their eyes or ears can cause irritation. Be very careful when washing them.^{[21]XResearch source}

While mice have a slight odor, they are self-cleaning. They are not naturally smelly. If they are producing an unpleasant scent that is not a result of dirty surroundings, they likely have a health issue. Take them to a veterinarian.^{[22]XResearch source}
