Guinea Pig Poop: 7 Different Shades and What They Mean

Guinea pigs are very good at hiding their illnesses and may even go unnoticed for a long time. Although your pet’s poops are not a glamorous topic to talk about, it is essential if you want to know about the overall health of your guinea pigs.

As a new guinea pig owner, you may be wondering what a healthy guinea pig poop should look like.

A healthy guinea pig poop is usually dark brown, firm, round in shape, and does not smell. Healthy guinea pig poop can also be dark in color, with glossy surfaces that will stick with each other.

In this article, we will highlight everything you need to know about guinea pig poop, from what a guinea pig poop looks like to the different shapes and sizes of guinea pig poop and what they mean.

What Do Guinea Pig Poop Look Like?

A guinea pig is usually in a pellet form, and it looks like a fibrous, round ball. The poop pellets will be hard, break into grains, and will be fibrous inside with no stickiness if pressed.

A guinea pig poop has a grainy feel of crushed hay because a large part of their diet is grass hay.

The poops are usually medium to dark brown in color and have an oval shape. However, a guinea pig may be a sign of trouble if the poop looks different. You should be more concerned if your guinea pig poop is soft, watery, and so on.


The color of guinea pig poop usually differs from one guinea pig to another. You can see a guinea pig poop looks dark brown while another looks light brown. The main thing is that a healthy guinea pig poop will be in the same color.

When you break a fresh poop, the inside is usually lighter than the outside color. However, your guinea pig can have variations in its poop color if you feed it with a different diet.

For instance, your guinea pig’s poop can be red if you feed them with beetroot.

Shape And Size

You cannot compare the size of a guinea pig with the size of poop pellets they excrete. For instance, an old guinea pig usually excretes small poop pellets, while a younger guinea pig can excrete massive pellet poop.

A healthy guinea pig poop is normal if the pellet size remains constant and round in shape. You should be concerned if your guinea pig poops are tiny or odd in shape, and this can be a sign that it has appetite loss, pain, and gastrointestinal issues.


A healthy guinea pig poop usually has a uniform consistency. The color, texture, size, and shape should be uniform. However, if you notice any variations, then they may be an underlying issue, and try to consult your vet for diagnosis.


A healthy guinea pig’s poop doesn’t smell, which is why it can be easily handled. However, their urine usually has a pungent smell.

This means you should be concerned about your guinea pig if poop excretes a terrible smell as it may be having underlying health problems.

Note: guinea pigs can also excrete cecotropes. This should not be confused with regular pellets as they have a strong smell but are suitable for your guinea pigs.
