10 things you may not know about guinea pigs


Nothing prepares you for the special challenge of caring for these pigs.

It’s 2am. In the light of the full moon they fan out across the grass. Our eco mowers, our living lawn ornaments, peacefully nibble in the glow.

At 7am there’s a cacophony. A scrabbling under the deck, high whistles, low rumbling. It’s a minor boy-gets-girl competition. The lawn is mown to the bone and they’re probably hangry (angry because they’re hungry).

Through the years of raising our family, the list of pets and foundlings has grown with an accompanying list of incidents that read like headlines:

Lamb Chops tears up neighbour’s lawn
Eels found in ensuite bathtub

But nothing could prepare me for pigs.

A few years ago, friends gave us – I think they called it ‘gifting’ at the time – 12 guinea pigs. They had too many living in and around their property, pets that had been set free.

Our boys were tremendously excited.  I resisted. Feeble squeaks.

“Do we need that many? What will we feed them? What if they stink?”

They were declared free range after a short time in a pen to acclimatise them to our block. They immediately made for our tin shed in a line-up, nose to tail.

I fell in love.


My morning routine quickly evolved into a trip to the fridge for carrots and apples. Then it was straight to the yard to see my new friends.

There is no sweeter sound than the squeals, chortles, and chatter of our group. Their excited bursts from one place of safety (the shed) to the next (the wheelbarrow). The way they hike themselves up when they run as if to reduce belly drag. The way they argue over a nugget of carrot, pulling back and forth until the one with the rugby player shoulders wins. The way they share it anyhow.

My heart swollen with happiness, I began to spread the love to friends, Instagram and Facebook. They wrote:
“Soooo cute!”
“Adorable.”
“What? Free range? Tell me more!”
“LOL good luck. Everything eats guinea pigs.”

Jason’s response made me freeze mid-scroll. But he had no idea of the nirvana we live in. All my meditating. That had to count for something. This relatively non-violent property of ours was a safe haven.

“Aren’t you afraid they’ll go viral?” asked Kaye.

“Ha, no worries about that,” I quickly typed. “Don’t you know everything eats guinea pigs?”

That may have been an ill-fated comment.

It was a rainy afternoon. We were lounging on the deck when the boys spotted a commotion in a puddle at the edge of the property. They were off like a shot, no questions asked, hailing rocks at the enemy.


They returned with Erica. She was a quivering wreck, having barely survived a near drowning and neck puncture by a low-down, conniving, murderous stoat. In broad daylight!

We have been on high alert ever since. But the stats are clear. Everything eats guinea pigs.

We also ended up with rats taking newborns. A full-scale rat trapping mission was launched. I’m saving up for a Goodnature™ Rat and Stoat trap.

Friends with dogs visited under my watchful eye. One found a boar almost as big as him.

Guinea pigs are busy, despite the dangers. When numbers swell and tempers flare, bands of brazen pigs head off to our other sheds to start a life of their own. I’m not one to pass comment on anyone’s lifestyle but there’s a lot of hanky-panky that goes on between brothers and sisters.

The fact that guinea pigs are low on the food chain makes rapid reproduction (some would call it viral) essential. Piglets are born fully furred, eyes open, ready for independent living.

Our sons know every muzzle, every malformed toe, and battle-scarred ear. They’re able to keep track of the genealogy and migrations around the yard. They simply accept the course of nature and our guinea pigs’ position in the animal kingdom.

My heart expands and contracts relative to current events. I exalt their free-range status while ferociously defending their precarious existence.

10 THINGS YOU MIGHT NOT KNOW ABOUT GUINEA PIGS

• Guinea pigs are not from Guinea and are not pigs. They are domestic versions of the wild cavy, a small rodent native to Venezuela, Peru and Brazil. They are more closely related to beavers and chinchilla than to rats and mice.

• They have been kept as pets for hundreds of years. Queen Elizabeth 1 had them as pets in the 1500s.

• They can weigh 500-1200g, and live (on average) 5-7 years, sometimes up to 10 years. The world’s oldest known guinea pig made it to 15.

• In parts of South America, cavies are an important source of meat as they are fast to breed, quick to grow and much easier to manage than larger livestock like sheep or cattle. The meat is high in protein and low in fat. Some say it tastes like a cross between pork and rabbit, others say chicken and duck. All agree it is oily, similar to duck.

• A happy guinea pig jumping into the air and bucking is ‘popcorning’.

• Males are boars, females are sows, babies are pups, and a group is a herd.

• Guinea pigs are naturally quiet but do have a vocabulary. They whistle and squeak when excited, and purr (like a cat) when relaxed (deep pitch), when annoyed (high pitched) or when scared (short). They hiss or chatter when angry or aggressive.

• Food bowls need to be hard plastic, stainless steel or ceramic as guinea pigs will chew up anything less robust.

• Guinea pigs are vegetarian and can be quite fussy. Introduce them to a wide variety of foods when they are young, as they don’t cope well with changes to their diet as adults.

• Guinea pigs are great nappers. They will sleep for short periods (30 seconds to 5 minutes or so) at any time of the day or night, for a total of about four hours per day. They often sleep with their eyes open, looking like they are in a trance. An animal in a very relaxed state will close its eyes.
