Small Mammal Care: A Comprehensive Guide to Guinea Pig and Rabbit Health

Guinea pigs (Cavia porcellus) and rabbits (Oryctolagus cuniculus) are popular small mammals kept as pets around the world. While they may seem similar, their dietary needs, environmental requirements, and susceptibility to certain diseases differ significantly. This guide provides a comprehensive overview of essential aspects of guinea pig and rabbit care, focusing on health and well-being. Whether you are a seasoned pet owner or considering welcoming these delightful creatures into your home, understanding their specific needs is crucial for ensuring a long and happy life for your furry friends.

Understanding the Basics: Guinea Pigs and Rabbits

Before delving into specific care guidelines, it's important to understand the fundamental differences between guinea pigs and rabbits.

• Guinea Pigs: These social creatures are native to the Andes region of South America. They are herbivores and require a diet rich in Vitamin C, which they cannot synthesize themselves.
• Rabbits: Originating from Europe and North Africa, rabbits are also herbivores with complex digestive systems designed to process large amounts of fiber. They are known for their crepuscular activity, meaning they are most active during dawn and dusk.

Creating a Healthy Environment

The environment plays a critical role in the health and well-being of guinea pigs and rabbits. A suitable living space should provide adequate space for movement, exploration, and rest. Consider these factors:

Cage Size and Design

Both guinea pigs and rabbits need spacious cages. For guinea pigs, a minimum cage size of 7.5 square feet (approximately 0.7 square meters) for one or two guinea pigs is recommended. Rabbits require even more space, with a minimum of 8 square feet (approximately 0.74 square meters) for a small rabbit and larger cages for bigger breeds. The cage should be made of durable, non-toxic materials, and the bottom should be solid (avoid wire mesh, which can injure their feet).

Example: In Australia, many pet owners use converted dog crates for rabbits, providing ample space and easy access for cleaning.

Bedding

Appropriate bedding is essential for hygiene and comfort. Suitable options include:

• Paper-based bedding: This is highly absorbent and dust-free, making it a good choice for both guinea pigs and rabbits.
• Fleece liners: These are washable and reusable, providing a soft and comfortable surface. They require more frequent cleaning than disposable bedding.
• Aspen shavings: While a popular choice, ensure they are kiln-dried and dust-extracted to avoid respiratory irritation. Avoid cedar and pine shavings, as they contain oils that can be harmful.

Temperature and Ventilation

Guinea pigs and rabbits are sensitive to extreme temperatures. The ideal temperature range for both is between 18°C and 24°C (65°F and 75°F). Avoid placing their cages in direct sunlight or near drafts. Good ventilation is crucial to prevent the buildup of ammonia from urine, which can irritate their respiratory systems.

Enrichment and Toys

Providing enrichment is essential for preventing boredom and promoting mental and physical well-being. Consider these options:

• Guinea Pigs: Provide tunnels, hideaways, chew toys (wooden blocks, cardboard tubes), and opportunities for social interaction (ideally with another guinea pig).
• Rabbits: Offer tunnels, cardboard boxes, chew toys (wooden toys, willow balls), and opportunities for exercise and exploration. Rabbits also enjoy digging, so providing a digging box filled with shredded paper or soil can be beneficial.

Example: In Japan, some owners create elaborate rabbit-safe play areas with tunnels, ramps, and platforms to encourage exercise and exploration.

Nutrition: Feeding for Optimal Health

Proper nutrition is the cornerstone of guinea pig and rabbit health. While both are herbivores, their specific dietary needs differ.

Guinea Pig Diet

The guinea pig diet should consist primarily of:

• High-quality Timothy Hay: This should make up approximately 80% of their diet. Hay provides essential fiber for digestion and helps wear down their continuously growing teeth.
• Guinea Pig Pellets: Choose a high-quality, Timothy hay-based pellet specifically formulated for guinea pigs. Limit pellets to about 1/8 cup per day to prevent obesity.
• Fresh Vegetables: Offer a variety of fresh vegetables daily, focusing on leafy greens like romaine lettuce, kale, and parsley. Avoid iceberg lettuce, as it has minimal nutritional value. Vegetables should comprise about 10-15% of their diet.
• Vitamin C Supplementation: Guinea pigs require Vitamin C supplementation, as they cannot produce it themselves. This can be provided through Vitamin C-rich vegetables like bell peppers or through a liquid or tablet supplement.
• Fresh Water: Always provide fresh, clean water in a sipper bottle or bowl.

Important Note: Avoid feeding guinea pigs sugary fruits in large quantities, as they can contribute to obesity and dental problems. Also, never feed them chocolate, onions, garlic, or avocado, as these are toxic.

Rabbit Diet

The rabbit diet should consist primarily of:

• High-quality Timothy Hay: This should make up approximately 80% of their diet. Hay is essential for maintaining healthy digestion and preventing dental problems.
• Rabbit Pellets: Choose a high-quality, Timothy hay-based pellet specifically formulated for rabbits. Limit pellets to about 1/4 cup per 6 pounds of body weight per day to prevent obesity.
• Fresh Vegetables: Offer a variety of fresh vegetables daily, focusing on leafy greens like romaine lettuce, kale, and parsley. Root vegetables like carrots should be given in moderation due to their high sugar content. Vegetables should comprise about 10-15% of their diet.
• Fresh Water: Always provide fresh, clean water in a sipper bottle or bowl.

Important Note: Avoid feeding rabbits sugary fruits in large quantities, as they can contribute to obesity and dental problems. Also, never feed them chocolate, onions, garlic, or avocado, as these are toxic. Rabbits should also avoid beans, peas, corn, and potatoes.

Common Health Problems and Prevention

Guinea pigs and rabbits are susceptible to various health problems. Early detection and prevention are crucial for ensuring their well-being. Regularly observing your pet's behavior, appetite, and physical condition can help you identify potential problems early on.

Guinea Pig Health Problems

• Scurvy (Vitamin C Deficiency): Symptoms include lethargy, rough coat, poor appetite, and joint pain. Prevention involves providing adequate Vitamin C supplementation.
• Dental Problems: Guinea pigs' teeth continuously grow, and if not properly worn down by chewing on hay, they can develop malocclusion (misalignment), leading to difficulty eating. Provide unlimited hay and chew toys.
• Respiratory Infections: Symptoms include sneezing, coughing, nasal discharge, and difficulty breathing. Ensure good ventilation and avoid drafts.
• Pododermatitis (Bumblefoot): This is an inflammation of the feet, often caused by unsanitary cage conditions or wire-bottom cages. Provide soft, clean bedding and maintain good hygiene.
• Parasites: Guinea pigs can be affected by mites, lice, and ringworm. Consult a veterinarian for appropriate treatment.

Rabbit Health Problems

• Dental Problems: Similar to guinea pigs, rabbits' teeth continuously grow, and malocclusion is a common issue. Provide unlimited hay and chew toys.
• Gastrointestinal Stasis (GI Stasis): This is a life-threatening condition in which the digestive system slows down or stops. Common causes include insufficient fiber intake, stress, and dehydration. Provide unlimited hay and ensure adequate water intake.
• Respiratory Infections: Rabbits can be affected by snuffles (a bacterial infection) and other respiratory illnesses. Symptoms include sneezing, nasal discharge, and watery eyes. Ensure good ventilation and avoid drafts.
• Ear Infections: Rabbits are prone to ear infections, particularly in breeds with floppy ears. Symptoms include head tilt, loss of balance, and ear discharge. Consult a veterinarian for diagnosis and treatment.
• Parasites: Rabbits can be affected by fleas, mites, and intestinal parasites. Consult a veterinarian for appropriate treatment and preventative measures.
• Uterine Cancer (in female rabbits): Unspayed female rabbits have a high risk of developing uterine cancer. Spaying is recommended to prevent this condition.
• Flystrike: This occurs when flies lay eggs on soiled fur, and the hatched maggots feed on the rabbit's skin. It is a serious and often fatal condition. Maintain good hygiene and check your rabbit regularly, especially around the tail area.

Preventative Care: Ensuring a Long and Healthy Life

Preventative care is essential for maintaining the health and well-being of your guinea pigs and rabbits. This includes regular veterinary checkups, proper grooming, and careful monitoring of their environment and behavior.

Veterinary Checkups

Schedule regular checkups with a veterinarian experienced in treating small mammals. These checkups should include a thorough physical examination, dental evaluation, and parasite screening. Vaccinations are not typically required for guinea pigs, but rabbits may need vaccinations against certain diseases, depending on the region. For example, in Europe, vaccinations against Rabbit Haemorrhagic Disease (RHD) and Myxomatosis are often recommended.

Grooming

Regular grooming is important for maintaining healthy skin and coat. Brush your guinea pig or rabbit regularly to remove loose fur, especially during shedding season. Long-haired breeds require more frequent grooming to prevent matting. Nail trimming is also necessary to prevent overgrowth and potential injury. Guinea pigs typically need nail trims every few weeks, while rabbits may need them every month or two.

Hygiene

Maintain a clean living environment for your guinea pig or rabbit. Clean their cage regularly, replacing soiled bedding with fresh bedding. Spot-clean the cage daily to remove feces and urine. Provide fresh food and water daily, and clean food and water bowls or bottles regularly.

Observation

Pay close attention to your guinea pig or rabbit's behavior, appetite, and physical condition. Any changes in these areas could indicate a health problem. Contact your veterinarian immediately if you notice any of the following:

• Loss of appetite
• Lethargy
• Changes in fecal output (diarrhea or constipation)
• Nasal or eye discharge
• Difficulty breathing
• Skin lesions or hair loss
• Head tilt or loss of balance
