Why Diet Matters for Guinea Pigs

Unlike some small animals, guinea pigs cannot produce their own vitamin C, making diet management critical. A poor diet can lead to:

  • Scurvy (Vitamin C Deficiency) – causes joint pain and lethargy.

  • Obesity – from too many treats or sugary foods.

  • Digestive Issues – due to lack of fiber.

Providing the right food helps prevent these common health problems.


Core Components of a Guinea Pig Diet

1. Hay – The Foundation of Every Meal

Hay should make up 80% of your guinea pig’s daily diet.

  • Best Choice: Timothy hay or orchard grass hay.

  • Benefits:

    • High in fiber to support digestion.

    • Keeps teeth naturally worn down.

💡 Tip: Always keep unlimited fresh hay available.


2. Pellets – Concentrated Nutrition

High-quality pellets provide essential nutrients that hay alone may lack.

  • Look for pellets that are:

    • High in fiber (18% or more).

    • Fortified with vitamin C.

    • Free from added seeds, nuts, or dried fruits.

Example of High-Quality Pellets:
A guinea pig pellet with 25% fiber and stabilized vitamin C is ideal for daily feeding.


3. Fresh Vegetables – Daily Variety

Guinea pigs thrive on a variety of fresh veggies.

  • Safe Vegetables:

    • Bell peppers (high in vitamin C)

    • Romaine lettuce

    • Cucumber

    • Cilantro

    • Kale (small amounts only)

  • Avoid:

    • Iceberg lettuce (low nutrition)

    • Potatoes and onion family vegetables (toxic)

💡 Rule of Thumb:
Offer 1 cup of fresh vegetables per guinea pig each day.


4. Treats – Occasional Only

Treats should be rare and healthy.

  • Good choices: small pieces of carrot or apple.

  • Avoid processed, sugary treats — these can cause obesity and dental issues.


Foods to Avoid for Guinea Pigs

Some foods are dangerous and should never be fed to guinea pigs:

  • Chocolate or candy

  • Bread or processed grains

  • Dairy products

  • Meat or animal-based foods

  • Nuts and seeds

  • Avocado (toxic)

⚠️ Important: Always research new foods before offering them to your pet.
