Guinea Pig Feeding Guide

Introducing the Guinea Pig Feeding Guide! Choosing your guinea pig’s food each day can often seem rather complicated! We frequently get asked how to plan out guinea pig’s meals to ensure they are eating healthy without being bored. The internet often offers a variety of conflicting information.

This is why we have decided to put together our “Guinea Pig Feeding Guide” Before reading this guide it’s useful to read our other articles on What can I feed my guinea pig along with What is a guinea pigs diet?

Our guinea pig feeding guide is our version of “The Eatwell guide” which is a document produced in the UK that shows how much we should eat every day. It also includes the different food groups humans should be eating from.

The Wheekwell Guide shows what your guinea pig should be eating every day and which vitamins they require.  It’s a simple, easy-to-use guide for new owners and a reference point for guinea pig veteran owners!

The Guide Overview

This chart shows your guinea pig’s general daily requirements. These quantities are what you should aim for daily.

As you can see 80% of your guinea pig’s diet should come from [amazon link=”B08FR72CQV” title=”hay” /]. [amazon link=”B08FR72CQV” title=”Grass hay” /], in particular, is the best for wearing down teeth and aids a healthy digestive system. We prefer to give our guinea pigs a mix of both so they can nibble on one and play on the other.

10% Should come from [amazon link=”B0030UF96W” title=”dried guinea pig pellets” /]. Not all pellets are equal so aim to buy the ones that are not too high in calcium as this can lead to kidney and bladder stones. An easy way to check if your guinea pig has too much calcium in their diet is to watch out for milky white deposits in their urine.

Choose pellets that also have vitamin C added since guinea pigs are unable to make their own like us!

It’s important to remember that fresh water should also be included for your guinea pig! 

The remaining 10% of their diet comes from vegetables and herbs which we will cover in greater detail below:

What A Guinea Pig Eats In A Day

We have created the Daily Plate to show how to choose your meals for your guinea pig friends. There are also suggestions included as to what to choose for each category.

Below is the recommended amount each day for one guinea pig. We feed our guinea pigs vegetables and herbs twice a day.

One Vegetable High In Vitamin C

Guinea pigs need to be fed Vitamin C rich foods daily in order to keep healthy and ward off disease. If your vet has advised you that your guinea pig has a Vitamin C deficiency then it’s especially important to provide them with foods rich in Vitamin C. One portion is one chunk, slice or several leaves for the leafy vegetables.

  • Celery Leaves – Chop into small chunks and remove “vein” to avoid chocking
  • Collard Greens
  • Swiss and Red chard – Can cause diarrhoea
  • Spinach – Use caution as too much can cause kidney and bladder stones
  • Kale (curly or plain)
  • Brussels Sprouts – Introduce slowly as may cause bloating
  • Peppers – sweet or bell. Any colour
    Introduce slowly as may cause bloating

One Herb Rich In Minerals

Minerals are essential for healthy guinea pigs and the best way to provide these for your piggy is using herbs. Never feed your guinea pig dried herbs or frozen. Fresh is best and they are very easy to grow. One portion is a sprig or two.

  • Parsley (curly or plain) – It is high in calcium though
  • Coriander
  • Dandelion Greens – Ensure these are free from animal urine if collected from the wild.
  • Mint
  • Thyme

One Portion Of Mineral And Vitamin C Rich Vegetables

Cabbage-type vegetables are great for this requirement! They contain both magnesium and Vitamins however they can cause bloating. Below are a selection of vegetables for this category. One portion is one slice, chunk or a few leaves.

  • Broccoli  – Stems best to feed as opposed to florets. It can cause bloating.
  • Cabbage – Can cause bloating.
  • Cauliflower – Can cause bloating.
  • Corn on the cob
  • Radishes
  • Spring Green – the mildest of the group and able to be eaten almost daily. 

Other Green Stuff

The last guinea pig requirement is just some plain old greens to keep it interesting! It’s vital to get your guinea pigs used to a wide range of foods when they’re young as they tend to get rather fussy when they are older! 

  • Cucumber
  • Courgette
  • Lettuces – Red, green, butter, romaine but NEVER iceberg as it has no nutritional value.
  • Carrots – contain high amounts of Vitamin A which can cause liver problems
  • Turnip
  • Parsnip

We have also created a printable version of our guinea pig feeding guide. It’s great to have on the fridge or somewhere else that you will see it. Simply click to download!

    My guinea pigs will only eat carrots, romaine lettuce, timothy hay, and their pellets, bell peppers, parsley, cilantro and occasionally celery and apple. I have tried introducing other fruits and vegetables but they ignore it. They seem healthy (urine and feces looks fine). Am I a bad piggle mom?

      Hi Bobbie,

      Thanks for your comment. NO! You are most definitely NOT a bad piggie mama. Some guinea pigs just eat what they know. Since you’ve already tried to introduce new foods and they have rejected them, they are telling you they are perfectly happy with what you are feeding them.

      I’m curious, do they like dandelion leaves and petals? We are yet to find a piggie who can resist them!
