The Best Small Animal Food for Guinea Pigs: A Complete Feeding Guide
Guinea pigs are adorable, social pets that require a balanced diet to stay healthy and active. Choosing the best small animal food for guinea pigs can be overwhelming, especially for new pet owners.
In this guide, we’ll explore what guinea pigs should eat daily, which foods to avoid, and how to create a proper meal plan to support their growth and wellbeing.
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

Nuts and seeds
Avocado (toxic)
⚠️ Important: Always research new foods before offering them to your pet.
