How Much is a Guinea Pig at PetSmart?

Generally, the price for a guinea pig at PetSmart ranges from $30 to $50, depending on the store’s location and the specific breed of the guinea pig. For example, common American guinea pigs might be at the lower end of the price spectrum, while the Abyssinian or Peruvian guinea pigs, known for their unique fur, might be more expensive.

The Real Cost: Guinea Pig Care Essentials

While the initial purchase cost might seem reasonable, keep in mind that the real expense comes with providing proper care for your new pet. Here are some crucial elements you need to consider:


Guinea pigs require a spacious and well-ventilated cage to live in. On average, a suitable cage may cost anywhere from $40 to $200 or more, depending on the size and complexity of the enclosure.


Guinea pigs need clean, comfortable bedding. You’ll need to replace this bedding regularly to maintain hygiene, which can cost between $10 to $30 per month.

Food and Water

Guinea pigs require a balanced diet of pellet food, fresh fruits, vegetables, and an unlimited supply of hay. Expect to spend around $20 to $40 per month on food.

Health Care

Like any pet, guinea pigs may require occasional veterinary care, including routine check-ups and vaccinations. It’s crucial to factor in these potential medical costs, which can vary depending on your location and the specific health needs of your guinea pig.

Toys and Enrichment

To keep your guinea pig healthy and happy, you’ll also need to invest in toys and other enrichment items. These may include tunnels, chew toys, and exercise wheels, which can cost anywhere from $5 to $50.

The Value of Adopting from a Rescue

While purchasing from PetSmart or similar chains might seem convenient, it’s important to note that many guinea pigs are in need of adoption. Local animal shelters and guinea pig rescues often have these pets available for a small donation, often much less than the price at a retail store. Moreover, adopting a pet supports these organizations in their mission to rescue and rehome animals.

Essential Items and Their Costs

Adding a guinea pig to your family involves more than just the initial purchase or adoption fee. Let’s dive deeper into the necessary items you’ll need to keep your furry friend happy and healthy.

Cages and Habitat

While guinea pigs are small, they require ample space to move around. The recommended cage size for one guinea pig is seven square feet, but more is always better. A quality cage can range between $40 to $200, depending on its size and features.

Cages with a solid bottom are essential to protect your pet’s feet. Wire mesh bottoms, while sometimes popular in pet stores, can lead to injuries and are not recommended. Some owners opt for a DIY approach using C&C (cubes and coroplast) grids, providing a cost-effective and customizable option.

Food and Nutrition

Guinea pigs have specific dietary needs that must be met for them to stay healthy. They require a daily intake of Vitamin C, as their bodies cannot produce it naturally. Vitamin C enriched guinea pig pellets are a common way to supplement their diet, costing about $10-$20 per month.

Hay should make up the majority of their diet, as it aids in digestion and dental health. Depending on the type and brand, hay can cost around $10-$30 per month.

Fresh fruits and vegetables are another vital part of their diet, offering variety and additional nutrition. Keep in mind, though, that not all fruits and veggies are safe for guinea pigs, and some should only be given in moderation. Budgeting for this can vary but expect an extra $10-$20 per month.


Bedding not only keeps your pet comfortable but also absorbs waste and reduces odor. There are various types of bedding available, including paper-based bedding and aspen shavings. Cedar and pine shavings are to be avoided, as they can cause respiratory issues in guinea pigs. The monthly cost for bedding can range from $10 to $30 depending on the size of the cage and the type of bedding chosen.

Health Care

Regular health check-ups at the vet are crucial to detect any potential health issues early. The average vet visit can range from $45 to $55, but this can vary depending on your location and the specific needs of your guinea pig. Unexpected health issues could add to these costs, so it’s essential to be prepared.


Toys and hideouts provide stimulation and a sense of safety for your guinea pig. Chew toys also help keep their ever-growing teeth at an appropriate length. The cost of toys can range, but a budget of $20 per month should cover these expenses.

Other Considerations

Guinea pigs are social animals, so it’s recommended to have more than one. However, this means doubling up on care costs. Additionally, most guinea pigs live between 4-8 years, so it’s a long-term commitment.

Purchasing a guinea pig from a store like PetSmart might seem like the easiest route, but rescues and shelters often have many wonderful guinea pigs that need homes, often for a lower fee. Furthermore, employees at these organizations can provide a wealth of information on the care and keeping of your new pet.

The commitment to a guinea pig involves ongoing expenses that far exceed the initial cost of the pet. Careful consideration and preparation can ensure a happy and healthy life for your new furry family member.

In Conclusion: Is a Guinea Pig the Right Pet for You?

Purchasing a guinea pig from PetSmart or any other pet store is not just a one-time expense, but an ongoing commitment to the care and well-being of your new pet. While the initial price tag might range from $30 to $50, the monthly upkeep can be considerably more. However, for those ready for the commitment, guinea pigs offer a rewarding and affectionate companionship. And remember, adoption is always a worthy consideration.

Frequently Asked Questions About Guinea Pig Ownership

1. How often do guinea pigs need to be fed?

Guinea pigs should have access to fresh hay at all times, as it is essential for their digestive and dental health. They should also be given a portion of fresh vegetables daily, ideally rich in Vitamin C, and a small serving of specially-formulated guinea pig pellets. Fresh water should always be available.

2. Do guinea pigs need companionship?

Yes, guinea pigs are highly social animals and thrive in the company of their own species. Keeping at least two guinea pigs is generally recommended to meet their social needs. Just make sure to have same-sex pairs or neutered/spayed pairs to avoid unexpected babies.

3. Can I use a hamster cage for my guinea pig?

Hamster cages are generally not suitable for guinea pigs due to their size. Guinea pigs need more space to move around, with a recommended minimum cage size of seven square feet for one guinea pig.

4. How often do I need to clean the guinea pig cage?

A guinea pig’s cage should be spot-cleaned daily for droppings and leftover food. A complete cage clean, where you remove and replace all bedding, should be done at least once a week. Keeping the cage clean is essential for the health and wellbeing of your guinea pig.

5. Can guinea pigs be house-trained?

While guinea pigs can’t be house-trained in the same way as cats or dogs, they do tend to choose a specific corner of their cage as their toilet. Placing a litter box in this corner can make cleaning easier. However, guinea pigs may not always stick to using this area, so regular cage cleaning is still essential.

6. Can children handle guinea pigs?

Children can interact with guinea pigs, but always under adult supervision. Guinea pigs can be easily frightened and may bite if mishandled. Teach children to be gentle and respect the guinea pig’s space.

7. Can guinea pigs live outdoors?

While guinea pigs can enjoy supervised outdoor playtime in safe, enclosed areas, they should not be kept outside permanently. Outdoor conditions can expose guinea pigs to harsh temperatures, predators, and diseases.

8. What kind of veterinary care do guinea pigs require?

Guinea pigs require regular veterinary check-ups to monitor their health. Additionally, they may require dental care as their teeth continually grow and can become overgrown without proper diet and chew toys. Some guinea pigs may also need treatment for mites or other parasites. Always seek veterinary care if you notice any changes in your guinea pig’s behavior, eating habits, or physical appearance.

9. Can guinea pigs eat human food?

While guinea pigs can enjoy many types of fresh fruits and vegetables that humans eat, they can’t safely consume all human foods. Some foods, like chocolate, dairy, meat, and sugary snacks, are harmful to guinea pigs. Always check if a food is safe before offering it to your guinea pig.

10. How can I tell if my guinea pig is sick?

Signs of illness in guinea pigs may include changes in eating or drinking habits, lethargy, difficulty breathing, changes in droppings, weight loss, hair loss, or unusual sounds. If your guinea pig shows any of these symptoms, it’s essential to seek veterinary care immediately.

11. Can guinea pigs be bathed?

While it’s not usually necessary to bathe guinea pigs frequently, they may need occasional baths if they become particularly dirty or if recommended by a vet for a specific skin condition. Always use a small-animal shampoo and ensure the water is a comfortable temperature. Never submerge your guinea pig’s head in the water.

12. Do guinea pigs need vaccinations?

Unlike dogs and cats, guinea pigs do not require regular vaccinations. However, they should still have routine veterinary check-ups to monitor their overall health.

13. Are guinea pigs nocturnal?

Guinea pigs are not nocturnal, but they’re not strictly diurnal (active during the day) either. They have a series of sleep and wake periods throughout the 24-hour day, often being most active during dawn and dusk. This behavior is known as crepuscular activity.

14. Can guinea pigs be walked on a leash?

It’s generally not recommended to walk guinea pigs on a leash. They have delicate spines, and pulling or tugging can cause serious injury. It’s better to let your guinea pig have supervised free-range time in a safe, enclosed area.

15. Do guinea pigs bite?

Guinea pigs may bite if they’re scared, stressed, or not feeling well. However, they are generally gentle animals and biting isn’t common behavior. Regular, gentle handling from a young age can help your guinea pig feel comfortable and safe with you, reducing the likelihood of biting.

16. How long can guinea pigs be left alone?

Guinea pigs should not be left alone for more than 24 hours. If you’re planning to be away from home, you should arrange for someone to check on and care for your guinea pig at least once a day.
