Why Your Guinea Pig Has A Wet Bottom?

Why Your Guinea Pig Has A Wet Bottom?

If you notice that your guinea pig suddenly has a wet bottom that has a strong smell, this is a sign of Urinary Tract Infection (UTI), you should have it checked immediately to the vet. It is fine if there is no strong smell, then they might just have urinated on themselves or accidentally sat on areas where they urinated.

Urinary Tract Infection (UTI)

Urinary Tract Infection or UTI on guinea pigs may be common but is still alarming. The most prominent signs that your guinea pigs have UTIs are a wet bottom accompanied by a strong smell or foul odour, and they make sounds or cry during peeing.

Other signs include fever, pain when touching their lower abdomen, weight loss, lethargy, and lack of appetite, these signs usually show after 3-4 days upon infection, so it is imperative to have them checked up by the vet.

Treatments are first to confirm these medical concerns and treat them effectively, a clinical checkup at your local veterinarian is required right away. Antibiotics and maybe more testing (such as faecal tests) may be required.

Examples of antibiotics that can be administered are enrofloxacin, meloxicam for a couple of days or weeks, depending on the severity of the UTI. Owners should also encourage more frequent drinking of water to counter the toxins and bacteria.

Provide clean and fresh water regularly, add infused fruits such as cucumber to encourage drinking. You can also use unsweetened and natural cranberry juice, give using a syringe or infuse it with their water bowls, change regularly as well.

Enteritis Accompanied by Liquid Diarrhea

Enteritis Accompanied by Liquid Diarrhea

Signs of Enteritis accompanied by Liquid Diarrhea include lethargy, dehydration, appetite loss, sunken eyeballs, rough hair coat, soiling of fur near the genital and anal area, and the most prominent and visible, liquid or loose and watery stool. 

If you see any of these signs, have your pig checked up asap to avoid discomfort for them.

Causes of these are a bacterial and parasitic infections that can lead to diarrhea in guinea pigs. Sometimes overfeeding is also a cause that has high sugar and little to no fibre is also a common cause.

But don’t worry, this is easily treated once your vet has diagnosed that this is diarrhea. Treatment is relatively easy, which is making sure they drink plenty of water, so it is important to encourage rapid drinking for the pigs.

Giving them yogurt is also a good option. You can give commercial yogurt with the active ingredient probiotics to help increase the “good” bacteria in their digestive tract. If their diarrhea gets worse, your vet may administer antibiotics when necessary.

The Cage Is Being Left Too Long Between Cleans

The Cage Is Being Left Too Long Between Cleans

Guinea pig cages play an important role in their health, so it is definitely important to maintain a clean cage. Clean regularly like once a week no matter what reason.

If the cage is left too long between cleans, then the basic premise of this would be that the cage would have a musty or foul odour, the beddings are soiled, and in worst cases, depending on the bedding, fungi could grow.

The treatment here is simple as well. Just clean the cage by means of removing the guinea pigs, then remove everything inside the cage, spray with specialized cleaning disinfectant, or warm water mixed with vinegar, wipe everything off then let dry.

You might also need a cleaning brush to clean off the corners as well, just in case.

After this, change the substrate or bedding that you use, be careful with the dampness so to remove this, use a dry and clean cloth. then place all the items again inside, then put back your little guinea pigs. See? Easy as 1-2-3!

How To Clean A Guinea Pig’s Wet Bottom?

There are two ways of cleaning your guinea pig’s wet bottom. The first one is using guinea pig wet wipes that you can purchase online, or in your local vet store. Avoid using commercial products or wet wipes for humans, as these contain a strong ingredient that could cause hair loss for guinea pigs.

The next one is giving them a warm bath but only doing so regularly such as once a week. Guinea pigs are known to be relatively tidy and clean creatures so they can clean themselves and are not really fond of baths.

The last one is called a dry cleaning process and it goes as:

  1. Rub unscented and natural flour across their bottom, avoid using powder as this has the material Talc which is harmful to the guinea pig.
  2. Rub that flour or powder across your guinea pigs anal or genital area and allow it to mix with their fur.
  3. Brush out gently the area using a comb
  4. Remove and clean the area with a soft towel
