All About American Guinea Pigs

The History Behind The American Guinea Pig

Cavia porcellus, or cavies, as we like to call them, originated in South America, in the Andes to be specific. Over time, these little rodents were domesticated and by 5000 BC, they started to appear in folk art. A few years later, they made their way to Europe, eventually keeping company with royalty, presidents and modern-day celebrities.

Did you know – Queen Elizabeth I, President Theodore Roosevelt and Lady Diana Spencer were all proud owners of these cuddly little creatures?

Being the oldest, and arguably the most common breed of cavy has stood the American guinea pig in good stead over the years. According to the American Cavy Breeders Association (ACBA) that recognises 13 breeds, the American and American Satin are not only one of the three original cavy breeds but are still one of the most popular.

Any guesses as to the other two breeds that share this top honour? Well, you won’t be surprised to find out it’s the Abyssinian and Peruvian.

The American Guinea Pig’s Appearance

Like all guinea pigs, this particular breed looks somewhat like a furry potato, with its solid, cylindrical-shaped body, stout little legs and round ears. Of all the guinea pig breeds, the American guinea pig and its close cousin, the American Satin are probably the most recognizable.

Did you know – In some countries, the American guinea pig is referred to as the English guinea pig?

In terms of its short, straight coat, at first glance, you may think the American cavy is a little boring-looking in comparison, say to the Peruvian guinea pig or its hairless cousin, the skinny pig. But there is nothing dull about the breeds’ different colours and variations.

Caring For An American Guinea Pig

When it comes to caring for American guinea pigs, there are a few things you need to consider. Understanding what your cavy needs (and likes) will keep it happy and healthy, and of course, wheeling and popcorning with delight.

Carry on reading to find out how best to care for your American cavy!

Cage Size

Yes, American guinea pigs may be small, but they need a lot of space to explore, exercise and interact with their pals. As far as the correct cage size, when it comes to all piggy breeds, bigger is always better. Make sure the cage you choose has plenty of room for your guinea pigs to play together, as well as separate compartments where they can enjoy some alone time and sleep.

Check out our wide range of quality guinea pig hutches here.

Hutch Set Up

Setting up the hutch correctly is also important. Cavies love hay. They nibble on it throughout the day and burrow into it when it’s nap time. Make sure your guinea pigs have access to high-quality, dust-free hay all the time.

Other hutch essentials include food bowls, water bottles, shelters and nests as well as animal-friendly cleaning products.

Diet

As already mentioned, hay forms a large part of all breeds of guinea pigs’ diet. But they also need fibre-rich, fortified pellets or nuggets, and plenty of fresh veggies and fruit. Take care though, guinea pigs have a sweet tooth and some fruits may contain too much sugar. This can quickly lead to obesity and long-term health problems.

Exercise

Guinea pigs are extremely busy and most of their time is spent running about, foraging for food and playing. In fact, according to the RSPCA, they are active for 20 hours at a time, only stopping to take a quick power nap every now and then.

To ensure they’re getting all the exercise they need, we recommend a good size run where they can enjoy time outside their hutch or indoor cage.

Grooming

Like all cavy breeds, American guinea pigs are very good at keeping themselves clean. And unlike long-haired breeds that are prone to matting or knotting, the American cavy is considered low-maintenance when it comes to brushing and trimming its fur. Keep in mind, however, sick or senior piggies may need a little help in the grooming department.

Health

Without the correct care, all guinea pigs, including the American guinea pig, is susceptible to a few health problems. Unfortunately, being prey animals, cavies generally try and hide any injuries or illnesses, which is why regular health checks are essential.

The most common conditions to look out for include:

  • Eye infections
  • Respiratory problems
  • Teeth or dental issues
  • Tumours and abscesses
  • Scurvy
  • Diarrhoea
  • Heatstroke
  • Pneumonia
  • Vitamin C deficiency
  • Bumblefoot
  • Flystrike

To keep your piggy as healthy, and happy as possible, always make sure:

  • Your guinea pig has a fresh supply of hay throughout the day.
  • Your cavies have access to clean drinking water 24/7.
  • The cage is kept clean and wet or soiled hay and poop is removed daily.
  • Your cavy is fed a well-balanced diet with plenty of pellets and vegetables that are rich in vitamin C.
  • The hutch is set up in an area that’s not too hot or too cold. Cavies are sensitive to extreme temperatures.
  • Your piggy’s nails are kept short and that there are no hard or sharp objects in the cage.
  • There are no poisonous plants or flowers anywhere near the hutch or run.
  • Your guinea pigs are supervised while they’re in their run or outside the cage and don’t keep other animals, like rabbits, in the same enclosure.

If you notice that your piggy has a decreased appetite, is lethargic or acting more aggressive or timid than usual, it could be a sign that something is wrong. It’s important that you contact your vet immediately if you notice any changes in your pet’s behaviour.
