Guinea Pig Care Sheet

Guinea Pig Overview

• Guinea pigs are native to South America and are also known as “cavies.” 

• Pet parents might see their guinea pig jumping and hopping in joy. This display of happiness is called “popcorning”! 

• Guinea pigs can be diurnal or crepuscular. Guinea pigs prefer a consistent schedule for feeding, playtime, and sleeping each day. 

• Guinea pigs are friendly animals and can enjoy being handled when properly socialized. Pet parents should allow newly homed guinea pigs time to acclimate to their surroundings. 

Guinea Pig Characteristics 

Guinea Pig Supply Checklist

To keep their guinea pig happy and healthy, pet parents should have these basic supplies on hand: 

• Appropriately sized habitat (36” L x 30” W x 18” H) 

• High-quality pelleted guinea pig food 

• Timothy or other grass hay 

• Treats 

• Bedding 

• Food bowl/water bottle 

• Hideaway place 

• Toys 

• Hay rack 

• Wood chews 

• Mineral chews 

• Vitamin C supplement 

• Soft brush and nail clippers 

• Cardboard chew tubes 

Guinea Pig Handling

Guinea pigs are typically easy to handle. They are social and curious and, if properly socialized, will approach the hands of their owners to be picked up from their cage. Pick up a guinea pig using two hands, with one supporting their rump and the other scooped under their front half.

Timid or nervous pigs may try to jump or run when picked up, but they rarely bite. If a guinea pig is dropped they are most likely to fall face-first. If that happens, inspect their mouth for broken teeth and seek help from your veterinarian if necessary.

Recommended Home for Guinea Pigs

Environment

Guinea pigs are prey animals and highly sensitive to sounds, lights, and smells. Quiet, peaceful areas of the house like a bedroom or home office work well for housing their enclosure. Bedrooms are not ideal choices as guinea pigs are nocturnal. Never place their enclosure in an area that receives direct sunlight, experiences large temperature changes throughout the day, or is immediately in front of an air conditioner or heating vent.

Pet Parents

Guinea pigs make fantastic pets for both adults and children. Their larger and bulkier size compared to other rodents can make handling easier and safer for smaller children. Guinea pigs can also be very affectionate.

Other Pets Guinea Pigs Can Live With

Guinea pigs prefer to live and interact only with other guinea pigs because they are being sensitive prey animals. Other docile pets can be around if the guinea pigs tolerate it. Guinea pig enclosures are often open-topped. If choosing this setup, it is imperative to keep dogs and cats away.

Family Friendliness Level

Guinea pigs are some of the most family friendly pets you could choose. They will give an adorable “wheeking” sound when they’re excited to see you. Young children can be pet and interact with them in their enclosure, while older children can take them out and handle them. Anyone in the household of any age can enjoy living with them. Even babies will enjoy the sounds and movements of their pigs.

Guinea Pig Habitat

Enclosure

A typical guinea pig enclosure will have a solid floor base and wire sides and, if present, a top. Guinea pigs have sensitive airways so good ventilation is a must. While wire floors can be used, they are not recommended as this creates higher chances of various traumas and infections to the feet. A guinea pig enclosure should be approximately:

• 100 square inches of floor area per adult guinea pig

• Wire sides for topless cages need to be at least 10 inches high

• Bars spaced about one inch apart

Bedding

The solid floor of your guinea pig enclosure needs to have bedding or liners.

For pigs that aren’t litter box trained, you can choose from the following beddings:

• Wood shavings

• Shredded paper

• Processed ground corn cob

• Commercial pellets

Bedding materials to avoid include:

• Cedar shavings

• Sawdust

• Any particularly dusty bedding

For pigs that are litter trained (and they can be!) you can use cloth cage liners across the floor. Replaced these during regular cleaning, and use corner litter boxes with either processed ground corn cob or commercial pellets. DO NOT use cat litter for a guinea pig litter box.

Feeding Dishes

Guinea pig food can be placed in either bowls hanging from the wire sides of their enclosures or a heavy ceramic bowl with low sides they can’t tip over. Hay makes up a large portion of their diet. Provide enrichment that supports their foraging behaviors by placing hay into foraging boxes or toys. You can also stuff tissue boxes (with all plastic removed), as well as toilet paper rolls.

Water can be offered to guinea pigs through either sipper bottles hung from the wire sides of their enclosure or heavy ceramic bowls with low sides, like their food bowls.

Guinea pig enclosures leave a lot of room for creativity. You can purchase cage kits and also design spaces for them that include tunnels, ramps, hide boxes, and more.

Guinea Pig Diet

Main Food

Guinea pigs are herbivores with specialized incisors that must constantly be worn down as they eat. To this end, about 80% of a guinea pig’s diet is made of grasses/hays, and food must be available at all times. Almost any grass hay is safe to offer. The only hay to avoid is alfalfa, as regular consumption can lead to health complications.

Guinea pigs also need fresh fruits and vegetables. Offer about quarter to a half cup of torn/chopped/shredded fresh fruits and veggies per guinea pig.

Commercially produced guinea pig pellets are available and can be offered in limited quantities. When offering pellets, make sure they are formulated with extra vitamin C, are based on grass/hay, and are not expired. Vitamin C level drop drastically in pellets more than 3 months beyond their production date. Feel free to offer pellets mixed in with their hay in their foraging toys/boxes rather than a bowl.

Water

A guinea pig’s water must always be fresh and clean and readily available. Water offered in a bowl should be changed daily or whenever dirty. Sipper bottles need to be cleaned before refilling and inspected for any damage, such as a stuck ball or a leaking tip.

Treats

Guinea pigs may be offered treats sparingly. Fruit or veggie based treats that are a good source of vitamin C are recommended.

Supplements

Guinea pigs don’t produce their own vitamin C and can become sick with scurvy if not provided enough in their diet. Vitamin C supplement treats can be given daily. Additionally, you can assess the vitamin C content of common fruits and vegetables.

Foods to Avoid

Avoid the following foods for your guinea pig:

• High-starch foods such as peas, beans, corn, nuts, cakes, cookies, cereal, grains, etc.

• Lilies

• Avocado

• Onions

• Raw potato

• Mushrooms

• Daffodils

• Chocolate

• Buttercups

Guinea Pig Daily Care

Feeding

Grasses/hays should always be available to your guinea pigs. You can offer their portion of fresh fruits and veggies at any point in the day. Remove any leftover fruit and veggies after a couple hours to avoid spoilage. Pellets can be offered at the beginning of the day for them to graze on as desired.

Grooming

Guinea pigs have low grooming needs. They should be checked daily for fecal matter or anything else stuck on their feet or bellies and spot-cleaned as necessary. Long-haired guinea pigs require a quick brush, but otherwise they do a good job of keeping themselves cleaned.

Nail care: Guinea pigs’ nails should be trimmed at least once a month. If the pet parent accidentally clips into the guinea pig’s quick and their nail begins to bleed, they can use a styptic powder to stop the bleeding quickly 

• Cornstarch can be used in a pinch if styptic powder is not available.

• Pet parents should make sure that all bleeding has stopped before placing their guinea pig back into their habitat.

Dental care: A guinea pig’s teeth never stop growing, so daily chewing and grinding on hay, treats, and toys help keep their teeth at a manageable length .

• Although other rodents have yellow or orange tooth enamel, healthy guinea pig teeth should be white. Discolored teeth should be examined by a veterinarian. 

• Consult a veterinarian if a guinea pig’s teeth seem too long, if they are drooling excessively, or if they are dropping food when they eat.

Exercise

Guinea pigs should be allowed time to explore outside their enclosures for at least one hour every day.

Disinfecting/Cleaning

Beddings or liners should be replaced at least weekly, up to daily as needed. It is important that the schedule allows for cleanings before any moistness or smells have accumulated. Some of the most common health issues in guinea pigs are respiratory illnesses and foot infections. Food and water bowls should be cleaned daily, as should litterboxes.

Clean surfaces of the enclosure with a pet friendly all-purpose cleaner or dilute vinegar. Soak any toys in dilute vinegar and replace once dried.

Guinea Pig Enrichment

Guinea pigs are natural foragers. Encourage exercise of both mind and body by providing foraging boxes and toys. Guinea pigs can be trained to use a litter box, which significantly lowers the cleaning effort required to keep them healthy. They can also learn their names and be trained to come to you when you call.
