Provide Proper Nutrition

Proper nutrition is essential for the health of your guinea pigs. Here’s what you should include in their diet:

  • Fresh Hay: Hay aids digestion, wears down their teeth, and provides essential fiber. Offer them Timothy hay or orchard grass.

  • High-Quality Pellets: Provide specially formulated pellets that meet their nutritional requirements. Look for pellets rich in vitamin C and low in fat. Remember, pellets should only make up a small portion of their overall diet.

  • Avoid Toxic Foods: Keep guinea pig-friendly options and avoid toxic foods like chocolate, caffeine, onions, and garlic.

  • Hydration Station: Ensure your guinea pigs have access to fresh water daily in a clean water bottle or shallow bowl.

Regular Vet Visits

Regular check-ups with a knowledgeable veterinarian are essential for monitoring their health. Consider the following:

  • Routine Check-ups: Schedule annual or bi-annual check-ups to assess their general health, provide necessary vaccinations, and address any concerns.

  • Special Considerations: Older or sick guinea pigs may require more frequent veterinary visits. Keep a close eye on their behavior and physical condition.

  • Prompt Attention: Seek veterinary care promptly if you notice any unusual symptoms or behaviors.

Clean and Safe Cage

A clean and safe living environment is vital for the well-being of your guinea pigs. Follow these guidelines:

  • Regular Cleaning: Remove waste, soiled bedding, and uneaten food daily. Give the cage a thorough cleaning at least once a week.

  • Bedding Matters: Choose a suitable bedding material like paper-based bedding or aspen shavings. Avoid cedar or pine bedding.

  • Spacious Digs: Provide a spacious cage that allows them to move around freely and includes bedding, food and water dishes, toys, and a cozy hiding spot.

Appropriate Temperature

  • Stay Cool: On hot days, provide ways to beat the heat, like a ceramic tile or chilled water bottle wrapped in a towel. Ensure they have access to fresh water and a well-ventilated area.

Proper Handling

Ensure the safety and well-being of your guinea pigs through proper handling:

  • Gentle and Calm: Approach them with a gentle touch and a calm demeanor to avoid stress.

  • Supportive Hold: Provide support to their body when picking them up. Avoid squeezing or gripping them too tightly.
