Emma Stenhouse

Looking to add a cute guinea pig to your family this year? Before you go ahead and commit to any new pet, it’s a great idea to sit down and figure out exactly how much it’s going to cost you to keep them happy and healthy.

Guinea pigs are certainly less expensive to buy than some other pets, but that doesn’t mean they’re going to be cheap to keep in the long run. These sociable and affectionate pets are best kept in a pair, so you’ll have to budget for keeping at least two guinea pigs!

Besides the one-time costs, like buying your new guinea pigs and their cage, you’ll need to factor in monthly ongoing costs, like their food, and occasional costs, like veterinary care. Luckily, we’ve broken it all down for you! Keep reading to find out everything you need to know about how much it costs to own a guinea pig.

Bringing Home a New Guinea Pig: One-Time Costs

Before you go ahead and buy your new guinea pig, bear in mind that it’s usually recommended to keep these sociable animals in pairs. In the wild, guinea pigs live in groups, and they can find it stressful if they’re kept on their own. So while we’ve provided the cost for one guinea pig, you should aim to buy two pigs together.

They should be of the same sex or spayed and neutered to make sure you don’t end up with an accidental litter of guinea pig babies!

Free

You may find guinea pigs advertised as free to a good home. Make sure you ask questions to find out why they’re being rehomed, especially if you want guinea pigs that your children can handle.

Bear in mind that some free guinea pigs may be the result of accidental litters, and the owners may not have sexed the babies correctly. So, if you buy any, make sure you book an appointment with your vet to check which sex your guinea pigs are, and have them spayed or neutered if necessary!

Adoption

  • $20-40

Some animal shelters may have guinea pigs looking for new homes. These may have been surrendered to the shelter due to a family’s circumstances changing or because of allergies. They may be the result of an accidental litter of guinea pigs too. A shelter will usually carry out health checks and check if the guinea pigs are suitable for kids to handle.

The fee for adopting a guinea pig from a shelter will cover their costs, including veterinary care, mediation, and food.

Breeder

  • $25-50

From a breeder, a guinea pig will usually cost between $25-50. There are a few different varieties of guinea pig available and by purchasing your new pet from a breeder, you can take the time to find the specific type of guinea pig that you’re after.

Guinea pig breeders will also make sure they have an ethical breeding program in place, which means they’ll take time to carefully select the best combination of male and female guinea pigs to breed together, so their offspring has the best chance of being healthy.

Supplies

  • $100-500

Guinea pigs are active, so you’ll need to provide them with a large enough enclosure so they can freely run around. We recommend an enclosure with a minimum size of 10.5 square feet for two guinea pigs.

Many owners also choose to invest in a separate outdoor enclosure that you can place on your lawn during the day and move around so your piggies have outdoor time in the fresh air.

Guinea pigs are also relatively nervous in open areas, so it’s important to provide them with a small hideaway that they can use to shelter and feel safe.

You’ll need to buy everything on this list before you welcome your new guinea pigs home. You’ll find items in both the lower and higher price ranges, depending on your location. We’ve taken the average cost of each item to give you a rough idea of price, and you can either increase or decrease this, depending on your own budget.

Annual Expenses

  • $100-500 per year

Guinea pigs might be cheap to buy, but you’ll still have to spend a set amount each year on their care. Once you’ve covered the one-off expenses that we’ve covered above, you’ll have to budget for annual costs, like health care, food, and insurance.

Health Care

  • $200-$1,000 per year

Guinea pigs are generally low maintenance, so you can definitely keep them in good health on a small budget. But if you decide to spend more on their food or buy insurance, then your annual costs may increase. If your guinea pig has an accident and needs emergency vet care, then this will increase your annual spend significantly.

Guinea pigs need vitamin C supplements in addition to their regular food. You can buy these as tablets or drops. We’ve accounted for the cost of these in your initial set-up costs, but bear in mind that this will be a running expense.

Check-Ups

  • $50-100 per year

It’s always recommended to take your guinea pig to see a vet at least once a year. Your vet will check their overall health, including their weight, the state of their teeth, and so on. An older guinea pig or one with an ongoing health condition may need six-month check-ups.

Vaccinations

  • $0 per year

The good news here is that guinea pigs generally don’t need any vaccinations! We always recommend checking with your own vet, but as a general rule, you shouldn’t need to budget for annual vaccinations for your piggies.

Dental

  • $0-200 per year

Guinea pigs’ teeth grow constantly, so it’s important to ask your vet to regularly check that your guinea pig’s teeth are not becoming overgrown.

Most guinea pig’s teeth will usually wear down naturally as they come into contact or grind against each other and when they chew their hard food.

Some guinea pigs can suffer from malocclusion, which is when their teeth are not aligned correctly, so they become overgrown. A guinea pig with malocclusion may not be able to chew and swallow their food properly, so you may see drool around their mouths.

Malocclusion can be caused by an imbalanced diet, especially a lack of vitamin C. it can also occur when a guinea pig doesn’t have enough hard foods or chews to grind their teeth on. It also happens naturally in older pigs.

Treatments for Parasites

  • $10-50 per year

Guinea pigs need worming every three months with a wormer specifically designed for small animals. This is usually added to their water and can be ordered through your vet.

Emergencies

  • $0-500 per year

Guinea pigs are often less likely to need emergency treatment than larger pets like dogs and cats, as they spend most of their time in their cages. Nevertheless, it’s always a good idea to remember that at some point, it’s possible that any pet will need emergency medical care.

If your guinea pig eats something that they shouldn’t, is dropped by an inexperienced handler, or develops a problem, like blood in their urine, you may need to rush them to a vet and have to pay an unexpected bill.

Medications for Ongoing Conditions

  • $0-100 per year

Most guinea pigs won’t need any ongoing medication other than vitamin C supplements. Some varieties, like satin guinea pigs, can be more prone to developing osteodystrophy, which may need ongoing treatment.

Insurance

  • $50-200 per year

You may decide to insure your young guinea pig for medical expenses and pay a small monthly fee to help cover their veterinary expenses in the event that they need treatment. Depending on the type of cover that you choose, this may include pre-existing conditions, emergency vet care, and investigative examinations if your guinea pig develops a medical condition.

Food

  • $100-500 per year

There are many choices when it comes to guinea pig food, so it’s possible to keep your guinea pig healthy on a budget or pick a premium food that costs more. Make sure whichever brand you choose is designed specifically for guinea pigs, and contains added vitamin C.

Your guinea pig will need:

  • Pelleted food
  • Grass hay
  • Vegetables

You may also choose to supplement their diet with:

  • Chew sticks

Environment Maintenance

  • $50-200 per year

Guinea pigs are low maintenance when it comes to their environment. Once they have their hutch or enclosure sorted, your main expense will be bedding. Guinea pigs usually need their cages cleaning out every other day, and as they love to burrow into their bedding, you want to make sure they always have enough.

Entertainment

  • $0-100 per year

Guinea pigs will love having plenty of hideaways and chews in their cage, but the best way that you can entertain your piggies is to make sure they get plenty of daily enrichment. Allowing them time outside in a secure enclosure is a great way for them to get fresh grass and enjoy seeing something new.

Total Annual Cost of Owning a Guinea Pig

$200-1000 per year

The annual cost of owning a guinea pig can vary, and it’s totally possible to keep these small pets on a budget or to buy the best hutches and food that you can afford and keep your piggies in the lap of luxury!

As a general rule, guinea pigs don’t need much vet care but they can develop expensive conditions, like malocclusion or osteodystrophy, as well as suffer from accidents requiring emergency vet care.

Owning a Guinea Pig On a Budget

You can definitely keep a guinea pig on a budget, and they certainly don’t need fancy equipment. If you spend your money wisely on the best food that you can afford and economize in other areas, you’ll find that you can keep costs down.

Saving Money on Guinea Pig Care

As with any type of pet ownership, there are always ways and means to save money when it comes to caring for your guinea pig. You could order their hay in bulk rather than small bags, and your guinea pig won’t care what their food bowls or water bottles look like, as long as they’re clean!

You could build a cage or outdoor enclosure using offcuts from other DIY projects and spend your money on high-quality food instead.

Conclusion

Owning guinea pigs can cost as little as $200 in a year, after you’ve invested in one-time expenses like their cage. When it comes to food and equipment, there’s always a budget option and a premium choice, so whether you’ve got a strict budget or cash to splash on your new pet, you’ll find options to choose from.

If your guinea pig has an accident or develops a medical condition that requires ongoing care, then expect your annual costs to go up as a result. You may decide to insure your guinea pig from the outset, and most policies will cover multiple guinea pigs.

Food and bedding will make up the bulk of your annual expenses, but you can find these to suit most budgets, large or small. However much your guinea pig costs per year, most owners agree it’s well worth it in order to spend time with these adorable little animals!
