Rabbit Nutrition Essentials

Rabbits have a unique digestive system that requires a specific balance of fiber, protein, and nutrients. According to the House Rabbit Society, proper rabbit nutrition can prevent many common health issues including dental problems, gastrointestinal stasis, and obesity.

The Perfect Rabbit Diet

Unlimited Hay (80-90%)

Timothy hay, orchard grass, or meadow hay should be available 24/7. Hay provides essential fiber for digestive health and wears down constantly growing teeth.

Best Options:

  • Timothy Hay (adult rabbits)
  • Orchard Grass
  • Meadow Hay
  • Oat Hay (as treat)

Fresh Vegetables (10-15%)

1-2 cups of fresh vegetables per 2kg body weight daily. Leafy greens should make up 75% of vegetable portion, with other veggies making up the remainder.

Best Options:

  • Romaine Lettuce
  • Kale (in moderation)
  • Bell Peppers
  • Herbs (parsley, cilantro)

Limited Pellets (5%)

1/4 cup per 2kg body weight daily. Choose high-fiber pellets (18%+ fiber) with no colorful bits, seeds, or dried fruit added.

What to Look For:

  • Timothy-based for adults
  • Alfalfa-based for babies
  • No added sugars
  • Simple ingredient list

Occasional Treats (<1%)

Fruits should be given sparingly (1-2 tablespoons per 2kg weekly). Avoid sugary commercial treats and human foods.

Safe Treats:

  • Apple (no seeds)
  • Banana (tiny pieces)
  • Blueberries
  • Carrot (limited)

Pro Tip

Always introduce new foods gradually over 7-10 days to avoid digestive upset. Monitor your rabbit's droppings daily - any changes in size, shape, or frequency can indicate dietary issues. For high-quality rabbit food options, check our rabbit nutrition collection.

Guinea Pig Dietary Needs

Guinea pigs are unique among small pets because they cannot synthesize their own Vitamin C. According to veterinary research from Merck Veterinary Manual, Vitamin C deficiency (scurvy) is a common and serious health issue in guinea pigs.

Essential Guinea Pig Diet Components

Food Type Percentage Daily Amount Key Nutrients
Timothy Hay 70-80% Unlimited Fiber, Dental Health
Vitamin C Rich Veggies 15-20% 1 cup daily Vitamin C, Hydration
Guinea Pig Pellets 5-10% 1/8 cup daily Fortified with Vitamin C
Fresh Water Essential Unlimited Hydration

Best Vitamin C Sources for Guinea Pigs:

  • Bell Peppers: Especially red and yellow (higher in Vitamin C than green)
  • Kale: Rich in Vitamin C but high in calcium - feed in moderation
  • Broccoli: Includes leaves and stalks
  • Parsley: High in Vitamin C but also calcium
  • Strawberries: Occasional treat due to sugar content

Important Warning

Guinea pig pellets lose their Vitamin C potency within 90 days of manufacture. Store pellets in a cool, dark place and buy small quantities. Never give guinea pig pellets to other species, as they're specifically formulated with added Vitamin C that other pets don't need in such high amounts.

Hamster Diet and Feeding

Hamsters are omnivores with specific nutritional needs that vary by species. According to the Blue Cross, a balanced hamster diet should include seeds, grains, vegetables, and occasional protein sources.

Species-Specific Hamster Diets

Syrian Hamsters

Larger hamsters need more protein and variety. They enjoy foraging for their food and should have a mix of seeds, grains, and vegetables.

Daily Diet:

  • 1-2 tbsp hamster mix
  • Fresh veggies daily
  • Protein 2-3x weekly
  • Unlimited hay (optional)

Dwarf Hamsters

Prone to diabetes, so low-sugar diets are essential. Roborovski and Campbell's dwarfs have similar needs, while Chinese hamsters need more climbing exercise.

Special Considerations:

  • Low-sugar mixes only
  • Limited fruits
  • Monitor for diabetes signs
  • More protein than Syrians

Protein Sources

Essential for all hamsters, especially growing, pregnant, or nursing ones. Offer 2-3 times weekly.

Safe Options:

  • Mealworms (dried or live)
  • Plain cooked chicken
  • Hard-boiled egg (tiny piece)
  • Plain tofu

Foods to Avoid

Many human foods are toxic to hamsters. Always research before offering new foods.

Never Feed:

  • Onions & Garlic
  • Chocolate
  • Raw Beans
  • Citrus Fruits
  • Almonds (bitter)

Chinchilla Feeding Guide

Chinchillas have sensitive digestive systems adapted to high-fiber, low-fat, low-moisture diets. According to exotic veterinarians, improper chinchilla nutrition is a leading cause of health issues including dental disease, gastrointestinal problems, and liver issues.

Chinchilla Dietary Requirements

  • Hay: Unlimited timothy or orchard grass hay (80-90% of diet)
  • Pellets: 1-2 tablespoons of chinchilla-specific pellets daily
  • Water: Fresh, clean water available at all times
  • Treats: Limited to 1-2 small treats weekly (rose hips, oat sprays)
  • Chews: Apple wood, pumice stones, or hay cubes for dental health

Special Note

Chinchillas cannot properly digest sugars or fats. Never feed fruits, vegetables, nuts, or seeds to chinchillas. These can cause serious digestive issues including bloat and hepatic lipidosis (fatty liver disease). Stick to hay-based treats only.

Ferret Nutritional Requirements

Ferrets are obligate carnivores with unique nutritional needs. According to the American Veterinary Medical Association, ferrets require high-protein, high-fat diets with minimal carbohydrates.

High Protein Needs

Ferrets require 30-40% protein in their diet, primarily from animal sources. Plant-based proteins are poorly utilized and can cause health issues.

Fat Requirements

15-20% fat content is ideal for energy and coat health. Look for foods with named animal fats (chicken fat, fish oil) rather than plant oils.

Carbohydrate Limitations

Ferrets cannot properly digest carbohydrates. Foods should contain less than 20% carbohydrates, with fiber under 3%.

Common Feeding Mistakes

Overfeeding

Obesity is common in small pets. Follow recommended portion sizes and monitor body condition monthly.

Wrong Food Type

Feeding rabbit food to guinea pigs (no Vitamin C) or dog food to ferrets can cause serious deficiencies.

Sudden Diet Changes

Always transition foods gradually over 7-14 days to avoid digestive upset.

Too Many Treats

Treats should never exceed 5% of daily intake. Sugary treats cause obesity and dental issues.

Vitamins and Supplements

Most small pets don't need supplements if fed a balanced diet, with two key exceptions:

  • Guinea Pigs: Require daily Vitamin C supplementation if not getting enough from fresh vegetables (30-50mg daily)
  • Ferrets: May benefit from salmon oil or ferret-specific supplements during shedding season
  • All Species: Probiotics can be beneficial during stress, illness, or antibiotic treatment

Final Thoughts

Proper nutrition is the single most important factor in your small pet's health and longevity. Each species has unique requirements, so never assume one pet's food is appropriate for another. Always consult with an exotic veterinarian for personalized dietary advice, especially if your pet has health issues. Monitor your pet's weight, droppings, and behavior regularly, as changes can indicate dietary problems.

Frequently Asked Questions

Can rabbits eat carrots every day?

No, carrots should be fed as an occasional treat, not a daily vegetable. While carrots are not toxic to rabbits, they are high in sugar and carbohydrates. Feeding carrots daily can lead to obesity, dental issues, and digestive problems. Instead, focus on leafy greens like romaine lettuce, kale, and herbs for daily vegetables. Carrots should be limited to 1-2 tablespoons per 2kg of body weight, 1-2 times weekly at most.

How do I know if my guinea pig is getting enough Vitamin C?

Signs of Vitamin C deficiency (scurvy) in guinea pigs include: lethargy, poor appetite, rough hair coat, swollen joints, difficulty walking, bleeding gums, and slow wound healing. To ensure adequate Vitamin C, feed daily servings of Vitamin C-rich vegetables (bell peppers, kale, broccoli) and use fresh guinea pig pellets (less than 90 days old). You can also supplement with 30-50mg of Vitamin C daily, either in liquid form added to water or as chewable tablets designed for guinea pigs.

What's the best protein source for hamsters?

The best protein sources for hamsters are: mealworms (dried or live), plain cooked chicken or turkey, hard-boiled egg (tiny piece), plain tofu, or cooked plain fish. Offer protein 2-3 times weekly. Syrian hamsters need more protein than dwarf varieties. Always cook meats thoroughly and avoid seasoning. For dwarf hamsters prone to diabetes, focus on lean protein sources and avoid high-fat options. Never feed raw meat or eggs due to salmonella risk.

Why can't chinchillas eat fruits and vegetables?

Chinchillas have evolved to digest very low-moisture, high-fiber diets in their native Andean mountain habitat. Their digestive systems cannot properly process the sugars and high moisture content in fruits and vegetables. Feeding these can cause: bloat, diarrhea, gastrointestinal stasis, and hepatic lipidosis (fatty liver disease). Even small amounts can be dangerous. Stick to hay, chinchilla pellets, and hay-based treats only.

Can ferrets eat cat food?

Some high-quality kitten foods can be used temporarily, but they're not ideal long-term. Ferrets need higher protein (30-40%) and fat (15-20%) than most cat foods provide. Look for ferret-specific foods or high-protein, grain-free cat foods as a better alternative. Avoid foods with: grains, vegetables, fruits, or plant-based proteins. The first ingredients should always be named animal proteins (chicken, turkey, lamb). Transition any food changes gradually over 10-14 days.

How often should I change my small pet's water?

Fresh water should be provided daily, and water bottles/dishes should be cleaned thoroughly every 1-2 days to prevent bacterial growth. Use a bottle brush for water bottles to clean the tube and valve. For bowls, wash with mild soap and rinse thoroughly. Always use filtered or bottled water if your tap water is heavily treated. In hot weather, check water more frequently as small pets drink more when warm. Dehydration can occur quickly in small animals.

What are signs of poor nutrition in small pets?

Common signs include: weight loss or gain, dull or patchy fur, overgrown teeth, soft or irregular droppings, lethargy, decreased appetite, changes in drinking habits, and behavioral changes. Specific signs by species: rabbits may stop eating cecotropes, guinea pigs may develop scurvy symptoms, hamsters may develop wet tail (diarrhea), chinchillas may have tooth problems, ferrets may develop insulinoma. Regular veterinary checkups (every 6-12 months) can catch nutritional issues early.
