Do Guinea Pigs Clean Themselves?

Many guinea owners want to know ‘do guinea pigs clean themselves?’ and if yes, do they need any additional grooming.

If you already have a guinea pig or two, you might have seen them cleaning themselves often.

But if you are about to buy/adopt a guinea pig, and are preparing yourself for its upkeep and maintenance, then we have valuable information about guinea pig grooming in this guide.

Do Guinea Pigs Clean Themselves?

Yes. Guinea pigs are fastidious little self-groomers. Like cats, guinea pigs constantly lick themselves to get clean. They also produce a whitish liquid from their eyes which they use to clean their tiny faces.

That is why guinea pigs do not need to be bathed too often. In fact; most guinea pigs hate water baths. You only need to bathe your pet if it is very dirty or stinky or has developed mites or other skin issues.

How Do Guinea Pigs Clean Themselves?

There are a number of ways in which guinea pigs groom and clean themselves. When your pet is young, its siblings/littermates or its mother will clean its fur by licking it.

As it grows older, it will learn to self-groom through licking, rubbing, nibbling, etc.

Young guinea pigs

As mentioned above, the mother guinea pig licks her babies clean- it is also a way in which she shows her affection to her babies.

That is why it is very important not to separate young guinea pigs from their mothers.


As your cavy grows up, it learns to self-groom.

  • Guinea pigs secrete whitish liquid from their eyes. They spread this liquid around their tiny faces with the help of their paws and rub their faces clean.
  • Your pet may also use its front and hind paws to gently eliminate mats, tangles, debris, or parasites from its fur.
  • Sometimes, they nibble their fur to remove hardened, crusted dirt from their coats.

Why Do Guinea Pigs Clean Themselves?

In addition to keeping their fur clean and free from dirt and parasites, guinea pigs self-clean for a variety of reasons. Some of these include instinctual behavior, self-soothing to feel safer, body temperature regulation, etc.


Every animal is born with certain instincts. Likewise, guinea pigs are “hard-wired or programmed” to instinctually clean themselves.

This information is coded into their DNA. The young pig instinctually learns to self-clean and groom as every pig is literally born with this knowledge. 

Moreover, young pigs also observe their grown-ups self-cleaning and continue the same behavior through observation.

For Safety

Guinea pigs also self-clean to eliminate and mask any odors that could attract predators in the wild.

In captivity, they continue self-grooming even though they do not have any predators around. Sometimes, a guinea pig who is anxious may self-soothe itself through cleaning, licking, and rubbing behavior. These actions release endorphins to reduce stress in the pig.

For Regulating Body Temperature

Guinea pigs do not have sweat glands, so they do not sweat. That is why they lick themselves extensively to lower their body temperatures in warmer months.

Their saliva helps them wet their fur and brings down their body temperatures, particularly when the weather is hot.

Why Do Guinea Pigs Clean/Lick Each Other?

Guinea pigs living in groups often clean and lick each other. This behavior also helps cagemates lick and groom the parts that the pig cannot clean on its own. Other reasons for this behavior are:

  1. To Assert Dominance

Guinea pigs follow a social hierarchy. They may lick and groom each other to assert dominance or submission. A meeker guinea pig will allow the dominant one to lick its coat to indicate complete surrender. 

  1. Courtship

Male and female guinea pigs follow a courtship protocol that involves sniffing each other followed by a licking session. This allows them to get familiar with each other’s scent and also get to know each other better prior to mating.

  1. To Show Affection

Older guinea pigs clean/lick the younger ones as a display of affection. A mother guinea pig will usually clean her babies to not only eliminate dirt from their fur but also as a sign of love.

Do Guinea Pigs Need to Be Cleaned?

Guinea pigs do not really need too much cleaning because they manage this job very well on their own. As far as possible, avoid bathing your guinea pig, because guinea pigs dislike water.

Also, water tends to leave their fur wet and, if not dried properly, could invite fungal skin infections.

Here are some factors to consider when it comes to guinea pig cleaning:

  1. It depends on the variety of guinea pig

Short-haired guinea pigs do not need too much cleaning, but if you see their fur is very dirty, you may consider wiping it down with a damp cloth or giving it a bath (if your pet is very dirty) once a month.

A long-haired guinea pig needs more grooming. Without daily brushing and regular hair cuts, its long, silky fur could get matted and tangled.

Brushing every day (or every other day) can eliminate these mats/tangles and also keep parasites at bay.

  1. Need to check your pet for health problems

Regular grooming of your guinea pig gives you an opportunity to watch out for lumps and bumps, and ensure your pet is healthy.

If your pet’s coat isn’t as glossy as it used to be, or you notice any skin lesions or parasites, it may be a good idea to check it out with a vet.
