The Ultimate Guide to Feeding Your Guinea Pig:
A Gourmet Approach to Their Diet
My dear reader,
Can you hear that soft rustling?
The gentle munching? That’s the sound of a content guinea pig, enjoying a delightful feast. Their tiny noses twitch with joy at the sight of fresh hay, crunchy vegetables, and the occasional sweet berry. Feeding a guinea pig isn’t merely about filling a bowl, it’s about creating a menu worthy of a small, furry connoisseur.

The Gourmet's Foundation: Hay, Glorious Hay
Imagine a world where your favourite food is also the healthiest option available. This is the reality for guinea pigs, whose diet should consist of 80-90% fresh, aromatic hay. It helps maintain their dental health, supports smooth digestion, and keeps their little bellies satisfied.
Here are some excellent hay options for your guinea pig:
- Timothy hay – the reliable classic, essential for adult guinea pigs.
- Orchard grass – a sweeter, softer choice.
- Meadow hay – a delightful mix of various textures and flavours.
- Alfalfa hay – ideal for young and pregnant guinea pigs (only for babies and expectant mothers!).
Always ensure their hay is fresh, golden, and free from dust or mould, only the finest for your little gourmet.
Vegetables: A Daily Delight
A guinea pig’s diet would not be complete without a daily serving of fresh, vibrant vegetables. Each bite should be both nutritious and tasty:
- Bell peppers – a colourful, Vitamin C-packed delight.
- Romaine lettuce – crisp and hydrating (but avoid iceberg lettuce; it’s all water, no nutrients!).
- Cucumbers and courgettes – refreshing, low-calorie treats.
- Fresh herbs – coriander, parsley, and basil add a touch of green luxury.
- Carrot tops – tasty, but limit actual carrots due to their high sugar content.
Variety is essential, and for guinea pigs, it’s also crucial for balanced nutrition. Mix up these choices to keep their meals interesting and their health in top shape.

Pellets: A Pinch of Perfection
Pellets, similar to a refined side dish, are an important part of a guinea pig’s diet. Only 5% of their daily food intake should consist of high-quality, plain pellets, avoid those with colorful bits, nuts, or seeds.
Serving size: Just 1/8 cup per day, a light sprinkle, not a mound
Fruits: The Occasional Sweet Symphony
The pleasure of enjoying a ripe strawberry, a slice of apple, or a handful of blueberries is undeniable! However, for guinea pigs, these treats should be reserved for special occasions. Their natural sugars make them a rare treat, just once or twice a week at most.
Safe fruits include:
- Strawberries, blueberries, and raspberries – tiny yet mighty in flavour.
- Apple slices – crisp and refreshing (always remove the seeds!).
- Oranges and kiwi – a zesty Vitamin C boost, but their acidity means moderation is key.
- Watermelon – hydrating, but oh so sugary, so keep it minimal.

Hydration: A Simple Sip
Your guinea pig should always have access to clean, fresh water. Provide it in a durable water bottle or a shallow dish, and be sure to change it every day. While they may not enjoy wine, they certainly deserve the best when it comes to staying hydrated.
Forbidden Feasts: What NOT to Serve
Not all foods are guinea pig-friendly. Steer clear of the following:
- Chocolate, dairy, or processed foods – just as bad as they sound.
- Onions, garlic, and leeks – toxic and dangerous.
- Potatoes or tomato leaves – harmful compounds lurk within.
- Iceberg lettuce – a watery waste of space.
- Avocado – too rich and unsafe.
The Art of Chewing: A Guinea Pig's Pastime
Their teeth never stop growing, so chewing isn’t just fun, it’s necessary.
Ensure they have:
- An endless supply of hay (the best dental care in the world!).
- Safe wooden chew toys.
- Untreated wooden sticks for extra gnawing enjoyment.
Keeping a Watchful Eye
Your guinea pig may not write restaurant reviews, but they will show you how they feel about their meals.
If you spot anything unusual, a visit to the vet is in order.
Keep an eye out for:
- Weight changes (too much or too little is a red flag!).
- Soft stools or signs of stomach troubles.
- Loss of appetite, never a good sign.
- Overgrown teeth, proof they need more hay.

Feeding your guinea pig well is a labour of love, a delightful blend of hay, fresh veggies, occasional treats, and endless care. With the right diet, your tiny gourmand will be healthy, happy, and ready to greet you with eager squeaks at every mealtime.
