Health Care


Guinea pigs need their regular checkups just like us! There are a few important things to consider when checking your guinea pig. Because cavies are prey animals, in the wild they wouldn’t show if they were sick until it was too late, otherwise a predator would pick them out very quickly. This is why our piggies need to be checked regularly to see if they are trying to hide something.

☘Things that need to be done every week!☘

Weighing your guinea pig


Weight loss is sometimes the first indication that something is wrong. Fluctuations in weight aren’t a problem, but if you notice an unusual drop, you must weigh your piggie each day to check that it is not continual.

If the weight loss becomes serious, you must seek a vet for further advice and to find out what is wrong. Make sure you cover all the possible options. Dental problems can sometimes be a cause of weight loss as chewing can become painful or uncomfortable.

Just as weight loss is an issue, weight gain can be serious too. You know that saying, killing by kindness. Overeating means that guinea pigs aren’t getting enough nutrition in their diets. Lack of nutrition makes them hungry because their body is telling them to eat more to get enough nutrients to sustain them. This in turn, leads to weight gain.


Another cause of weight gain is usually lack of exercise while sitting on good diet of grass, veggies, pellets and hay. No matter how well the diet is, your piggie is going to put on weight if he or she is not getting sufficient exercise in its day. Obesity leads to diabetes and a whole host of other problems!


A guinea pigs eyes should be glossy and round- the sign of a healthy eye!

Milky white fluid is also a sign of a healthy eye because it is a natural substance that your piggie secretes to keep the eye clear so they don’t need to blink. Some cavies have visible droopy lower lids full of white fluid and some don’t.


What to look for: signs of irritation in the eye including puffed up lids, visible irritation like redness, swollen or protruded eyes. Hay or debris stuck in the eye should be removed with caution. If you suspect that something is gotten in its eye you should take your piggie to the vet and get it flushed out. Other times, eye problems can be a symptom of something else that needs to be diagnosed.


Some guinea pigs have naturally red or ruby eyes, this is not a problem!



guinea-pig-health-care-5A guinea pig’s teeth grow continuously, all the time! This is because they are chewing consistently on their hay, pellets and whatever else they can get. In order to keep their teeth down, guinea pigs must have something to chew on at all times- wooden branches and toys.

If you suspect that your guinea pigs teeth are too long or chipped, the vet can trim off the ends for you quite easily.

To check inside the mouth, press both fingers on each side of the jaw. Your guinea pigs mouth will be gently forced open and you can see whether there are any signs of infection (cheilitis) or chipped, broken or misaligned teeth. Note: you will not be able to see the molars at the back. Only a vet with a light and specialized equipment.

Grease Gland


I’ve written a whole article on how to clean your guinea pigs grease gland but I’ll touch up on it briefly. You may not even have realized they even had a grease gland because its usually covered up with fur!

The grease gland is located on the base of the tail, as you can see by the picture. However, when you clip away the hair around it and take a look, you’ll see that its either clean, or covered in dried yellow/black grease. If it is clean then you are lucky to have a guinea pig with an nonactive gland, it will only need to be cleaned every now and again. However, if your piggie has an active grease gland- you will need to clean it every three weeks. Depending on how mucky it gets.

If you don’t clean it, it may become infected and will feel uncomfortable for your piggie. You will need 100% pure coconut oil, critter friendly shampoo, a wet cloth and some water. See instructions HERE.

    Well, I’ve never owned a guinea pig, but health care is as important to us as it is for anything. If I ever happen to own one now I know where to look for the right instructions.

    So, will teeth keep growing even if the length is out of ordinary?

    About the grease gland, what function does it have in the guinea’s pig system? I had no idea such gland was placed there because of the visibility issues you mentioned.

      Hi, yes teeth grow continuously. They would grow down through the lip if it was serious. Sometimes the vet needs to trim down the teeth to prevent issues with eating. The grease gland is used for territory marking. Some guinea pigs are more prone to marking their territory then others and these are usually the more dominant ones.

    Great article on such an important topic! I feel like healthcare for these smaller guys like Guinea Pigs, Rabbits, and Chinchillas is forgotten far too often because people see them as “low maintenance pets”. I remember when I was just enjoying looking at the Piggies in a pet store and the store clerk began his attempts to get me to buy one. When he mentioned how low maintenance they are and how vet visits are minimal and not usually necessary (I mentioned how I didn’t need more vet bills in my life). I was thrown off a bit, since I knew there was no way vet visits for these guys were rare, and I ended up just leaving store. It made me a little peeved that he would tell people that to make a sale, and after reading this post it makes me even more peeved! Glad you have this site to help people know the truth and make sure all Guinea Pigs are properly cared for!

      Wow yep that’s not the first time I’ve heard pet stores do that! All they care about are the sales they make and not the diet, housing or healthcare. I wish that pet store employers actually cared about animals 🙁

    Interesting, I didn’t know that guinea pigs had a grease gland! (Don’t worry, I don’t have one yet)
    I also didn’t know that they have milky white fluid in their eyes so they didn’t have to blink. I wish I had that, my eyes are always dry 😀 Thanks for sharing this information, lots of people have pets and don’t know how to take care of them properly. It’s concerning.

      It is very concerning- thanks for your comment 😀
