Pets are not just a source of entertainment but also wonderful companions. However, caged animals like guinea pigs can sometimes produce unpleasant odors. The best way to minimize this smell is to maintain a clean living environment for your guinea pig. Most healthy guinea pigs know how to groom themselves, but long-haired breeds may struggle with this task.
Steps
Maintain a Clean Environment

Clean the cage at least once a week. This involves removing all used bedding, not just cleaning visibly dirty spots. After disposing of the dirty bedding, wash the cage floor and corners thoroughly with water and soap, rinse off the soap, and replace it with fresh bedding.
- After washing with soap and water, you can use a diluted 10% white vinegar solution (1 part vinegar to 9 parts water) as a disinfectant before drying the cage floor. Using this solution weekly (after cleaning the cage) helps effectively eliminate odors.

Clean dirty spots in the cage daily. Especially if you have multiple guinea pigs in one cage, you need to clean the soiled areas every day in addition to the weekly deep cleaning. For daily cleaning, simply wipe down and remove the dirty bedding at the end of the day.
- Most guinea pigs designate a specific area in the cage as their bathroom. Cleaning this area daily will significantly help reduce odors and keep their living environment fresh.

Train your guinea pigs to use a litter box. Daily cleaning becomes much easier once you teach your guinea pigs to use a litter box. Identify the area where they usually relieve themselves and place a small mammal litter box there.
- To help your guinea pigs get used to the new litter box, place some soiled bedding and a few droppings inside to signal that this is their designated bathroom area.
- Reward your guinea pigs when they use the litter box correctly. If they change their bathroom spot, try moving the litter box to the new location.
- Clean the litter box daily. Sprinkle a bit of baking soda at the bottom to neutralize odors.
- Never use cat litter in the guinea pig's litter box. Instead, opt for bedding materials specifically designed for small animals.

Use cage cleaning sprays designed for small animals to help minimize odors. Look for these sprays at pet supply stores to ensure you get a safe and effective product.
- To use the cage spray, remove all used bedding. Then, spray a generous amount of the cleaning solution around the cage.
- Let the spray sit for 3-5 minutes.
- Use a dry cloth to wipe away the spray and any stubborn stains on the cage floor.
- Allow the cage to dry completely (preferably in sunlight), add fresh bedding, and return your guinea pigs to their home.
- You can also use soap and water alongside the cage cleaner for a thorough cleaning.

Use odor-control bedding. Bedding like CareFRESH Advanced Odor Control Small Animal Bedding can help keep the cage smelling fresh for longer.
- Spread a layer of bedding about 3-8 cm thick at the bottom of the cage. Make sure to clean out soiled bedding daily.
- While odor-control bedding can reduce smells, you still need to clean the cage and replace all used bedding at least once a week.
- Baking soda is often advertised for odor control, but it can cause irritation and should not be used.
Bathing Your Guinea Pig

Bathing guinea pigs is only necessary to keep them clean. Most guinea pigs can groom themselves, but long-haired breeds may require more frequent baths.
- Bathing guinea pigs can increase their risk of illnesses, such as colds. To avoid this, wrap your guinea pig in a warm towel until its fur is completely dry.
- To minimize the need for baths, regularly brush their fur. Use a soft baby brush to groom your guinea pigs. You can also trim their fur to prevent it from getting soiled during bathroom use.
- If you feel your guinea pig needs frequent baths, consult a veterinarian about the potential risks and effects of regular bathing.

Use the appropriate soap. Ensure the soap you use is safe for guinea pigs. Avoid human soaps and dish detergents, as they contain harsh chemicals that can irritate their skin.
- Some soaps specifically designed for guinea pigs include Scentsations Premium Small Animal and Posh ‘n Go Protein.

Regularly check your guinea pig's ears. Guinea pig earwax is typically gray and odorless. If your pet's ears smell bad or appear red, visit a vet as they may have an ear infection.

Feed your guinea pigs long-stemmed grasses like timothy hay. This helps them wear down their teeth and maintain a balanced digestive system. Add mint leaves, celery, cilantro, and other herbs to their cage to keep it fresh and provide healthy snacks.

Avoid feeding your pet inappropriate foods. Some foods, like cabbage, broccoli, and Brussels sprouts, can cause bloating and stomach discomfort in guinea pigs.
- Healthy snack alternatives include bell peppers, cucumbers, and celery. Leafy greens like green or red lettuce are also great options. Avoid Romaine lettuce and kale, as they are high in calcium and can harm guinea pigs.
- Recommended foods for guinea pigs include kiwi, oranges, and bell peppers, which are rich in vitamin C, essential for their growth. Lettuce, kale, and beet greens are also excellent choices.
Tips
- Only bathe guinea pigs when they genuinely smell bad. Guinea pigs are surprisingly clean mammals in most situations.
- Ensure you dry your guinea pig thoroughly after bathing to prevent them from getting cold.
- When bathing guinea pigs, avoid letting water enter their ears. Cleaning their bottom and belly is sufficient!
- Female guinea pigs tend to smell less than males. If you're undecided on which to choose, consider adopting a female guinea pig.
- Regularly trim the fur of long-haired guinea pigs to keep them clean.
Warnings
- Frequent bathing can strip guinea pigs of essential oils needed for their skin and fur. Over-bathing may cause bald patches. Bathing them more than once a month is unnecessary and not recommended by veterinarians.
- Gradually acclimate your guinea pig to bathing. Start by letting them sit in warm water, offer their favorite treats, and slowly pour water over their body. Once they’re comfortable, you can introduce soap and rinse. While not all guinea pigs enjoy baths, they can learn to tolerate the process.
