Some guinea pig facts have been fairly commonly known for years – as an example, guinea pigs are not pigs and not from Guinea, or even New Guinea. I thought it might be interesting to share some facts about pigs that might not be so well known, maybe even among guinea pig owners.

1. Guinea pigs produce a white milky looking fluid at the corner of their eyes. It is used to help them groom and is completely normal. Typically the fluid goes unnoticed, they groom themselves very quickly! Pigs use their front feet to wipe the fluid from their eyes around their faces and over their heads when they bathe.

2. Although guinea pigs don’t have great vision overall, they are not color blind.

3. Guinea pigs have what are known as “open rooted” teeth, which means the teeth grow constantly throughout their lives. Pigs need unlimited access to foods, especially grass hays, to help grind down their teeth in order to keep them to the proper length and alignment.

4. Grass hay should be a fundamental part of guinea pig diets. Some examples of grass hays are Timothy hays and Orchard Grass. Alfalfa is legume hay, not grass hay, and should not be fed to adult guinea pigs. Hay fills several needs for pigs – it has abrasive silicates in it to help wear down their teeth and the long-strand fibers keep their gastrointestinal tracts working properly to keep them healthy and happy. If you’ve ever seen a guinea pig dive in a pile of hay you know what I mean by happy!

5. Male guinea pigs can (and do) live together very happily. In the past it was a widely held belief that male pigs would inevitably fight if housed together, however piggy relationships are determined as much by personality as by gender.  Not any pair of males is compatible of course.

6. Male pigs (and females in some circumstances) will “rumblestrut” as a sign of courtship and/or dominance toward another pig. A rumblestrutting pig will typically have raised or puffy hair, be making a “brrrrrr” vibrating sound and swaying their hips back and forth.

7. Baby guinea pigs are born precocial, meaning they have all their hair, their eyes are open and functioning and their teeth are fully developed. Within a few hours they can run and within a day they can eat solid food although they do need to nurse from their mother for a while.

8. Because baby pigs are precocial they reach sexual maturity very fast.  A baby boy guinea pig can reach sexual maturity in 3-5 weeks and a female in as little as 4 weeks.  Young guinea pigs must be sexed by a vet or someone else with experience so the boys and girls can be separated early enough to prevent additional litters.

I hope you enjoy this post.
