Guinea Pig

There are different guinea pig breeds, which mainly differ in coat type, coat length, and appearance. Unlike some other pets, guinea pig breeds differ less in character; the main variation lies in their coat and grooming needs. Below are the most well-known types.

• Short-haired guinea pig (American/smooth coat): This is the most common guinea pig. The coat is short, smooth, and lies close to the body. Short-haired guinea pigs are relatively easy to care for, as their coat requires little maintenance. Occasional brushing is usually sufficient.
• Abyssinian guinea pig: This guinea pig is recognized by the so-called rosettes in the coat. These are small whorls that make the hair stand in all directions, giving it a slightly messy and playful appearance. The coat is short to medium length and usually requires a bit more grooming than a smooth coat.
• Long-haired guinea pig (Peruvian): This guinea pig has a very long, silky coat that grows over the body and can even fall over the head. These guinea pigs require daily grooming to prevent tangles and dirt in the coat. Sometimes the coat is lightly trimmed to make maintenance easier.
• Sheltie (Silkie): Similar to the Peruvian guinea pig, but the coat grows backward from the head. This keeps the face mostly free of hair. Regular grooming is also important for this breed to prevent tangles.
• Teddy guinea pig: The Teddy guinea pig has a short, dense, slightly curly coat that resembles a plush teddy bear. The coat stands slightly away from the body and feels firm. This breed generally requires less intensive grooming than long-haired breeds.
• Rex guinea pig: This guinea pig resembles the Teddy but has an even coarser and firmer coat texture. The hairs often stand more upright, giving the breed a distinctive appearance.
• Skinny guinea pig: A nearly hairless guinea pig. Only the nose, legs, and sometimes the shoulders have some hair. Because they have little fur, they are more sensitive to cold and temperature changes and require extra warmth and proper care.

In addition to these breeds, there are also other varieties and crossbreeds with different colors, patterns, and coat types. In practice, many guinea pigs are kept as pets without belonging to a specific breed. Their care and behavior are generally similar regardless of breed.

1. The basis of a guinea pig’s diet consists of unlimited hay. This is by far the most important part of their diet and must always be available. Hay is rich in fiber and plays an important role in healthy digestion. It also helps wear down the teeth, which continue to grow throughout a guinea pig’s life. Good hay therefore forms the foundation of a healthy diet.
2. In addition to hay, guinea pigs receive a daily guinea pig pellet. Prefer pellets where all pieces have the same size and composition. This prevents selective eating, where guinea pigs pick out only the tastiest parts. Mixed feeds with different colors, shapes, or additions are less suitable, as they often contain fewer fibers and can encourage selective feeding. A good pellet contains sufficient fiber and is specially formulated for guinea pigs.
3. Fresh vegetables are also an important part of the daily diet. Vegetables provide extra moisture, fiber, and essential nutrients. Especially vitamin C-rich vegetables are important, as guinea pigs cannot produce vitamin C themselves. Examples include bell pepper, broccoli, endive, or leafy greens. It is advisable to introduce vegetables gradually and vary them to keep digestion balanced.
4. Many guinea pig pellets already contain added vitamin C, but this is not always sufficient. Vitamin C can decrease or degrade over time, for example due to exposure to air, light, or heat. Because guinea pigs can quickly develop a deficiency, it is often wise to supplement their diet daily with a vitamin C tablet. Many guinea pigs see this as a treat, making it easy to give.
5. Dried herbs are also part of the diet. Dried herbs such as dandelion leaf, plantain, nettle, chamomile, calendula, or parsley can be a healthy and natural addition to their daily menu. Many of these herbs contain extra fiber, minerals, and sometimes vitamin C. However, it is important to give herbs in moderation. They are meant as a supplement alongside hay, pellets, and fresh vegetables. A small handful per day, or a mix of herbs a few times per week, is usually sufficient. This helps prevent imbalance in the diet.

By providing a diet mainly consisting of hay, supplemented with good pellets, fresh vegetables, herbs, and additional vitamin C, a guinea pig receives everything it needs for healthy digestion, strong teeth, and a good immune system.

Guinea pigs are true group animals and feel most comfortable when living with others of their own kind.

• The most stable combination is often one neutered male with one or more females. This most closely resembles their natural group structure and is often harmonious.
• Two or more females can also live together well. They usually coexist peacefully and often form a stable group.
• Two unneutered males can also be kept together, especially if they grow up together from a young age. However, tension may arise later when they mature and establish hierarchy. Males are often slightly more territorial than females.

Regardless of the group composition, sufficient space and multiple hiding places are important. This allows guinea pigs to avoid each other when necessary, helping to prevent conflicts and maintain a stable group.

A guinea pig lives on average 5 to 8 years. This can vary per animal, depending on factors such as diet, care, living environment, and genetics. Some guinea pigs live longer and can reach 8 to 10 years with good care, although this is less common.

An important factor for a long lifespan is proper nutrition. Guinea pigs have a sensitive digestive system and rely entirely on fiber-rich food. Unlimited hay, a good guinea pig pellet, and daily fresh vegetables (supplemented with vitamin C) help maintain their health. Because guinea pigs cannot produce vitamin C themselves, a long-term deficiency can lead to health problems.

Housing and social interaction also play a role. Guinea pigs are social animals and feel most comfortable when living with a companion. A spacious enclosure, a calm environment, and sufficient hiding places help reduce stress.

Yes, a guinea pig can live with a rabbit, but there are some important conditions.

The most important is that both species also have companionship from their own kind. This means you should keep at least two guinea pigs and two rabbits together. Guinea pigs and rabbits communicate very differently and do not always understand each other’s body language. When a guinea pig lives only with a rabbit, it can still feel lonely because it cannot share its natural social behavior with a fellow guinea pig.

It is also important that the enclosure offers enough space and safe hiding places. Guinea pigs are smaller and more vulnerable than rabbits. Therefore, there should be hiding spots that only guinea pigs can access, so they can retreat when needed. This helps prevent stress and possible accidents. For rabbits, it is also beneficial to have some elevated hiding spots that guinea pigs cannot reach.

Although cohabitation is possible, it is important to realize that guinea pigs and rabbits have different needs, for example in terms of diet and behavior. Therefore, it is often easier and safer to keep both species in their own groups.

Yes, guinea pigs can live outdoors, provided their enclosure is well adapted to the conditions. The enclosure must be spacious, dry, draft-free, and well insulated. It must also provide protection from rain, wind, direct sunlight, and predators.

In winter, extra attention is needed. Guinea pigs tolerate cold better when they gradually get used to it and when they live with companions, so they can keep each other warm. A well-insulated shelter with sufficient straw or hay helps retain heat.

In summer, shade and ventilation are important to prevent overheating. Guinea pigs are sensitive to high temperatures and must always have access to a cool place to retreat.

If the enclosure is safe, spacious, and sheltered, guinea pigs can be kept outdoors year-round. However, it is important to check daily whether they are healthy and eating and drinking sufficiently.
