Guinea Pig Feeding Guide

Guinea Pig Feeding Guide

Your guinea pigs’ diet needs to be high in fibre and protected vitamin C. Our guinea pig feeding guide is here to help you give your guinea pigs the best diet!

The Excel Feeding Plan

Following our Excel feeding plan will ensure that your guinea pigs get the correct balance of fibre, vitamins and minerals. 85-90% of a guinea pigs’ diet should be high quality, dust extracted feeding hay, such . Supplement this with a small portion of Excel nuggets, the occasional Excel nature treat, a small handful of fresh greens and plenty of fresh water.

Guinea pigs are herbivores who live on a plant-based diet. However, we like to call them ‘fibrevores’ as fibre is by far the most important part of their diet and is essential for their gut and dental health.

The Excel Feeding Plan

Types of fibre

Guinea pigs always need to keep their digestive systems busy with a mix of two kinds of fibre moving through the gut. These two types of fibre are called digestible fibre and indigestible fibre. Guinea pigs get this fibre mainly from good quality hay. We’d recommend Burgess Excel Feeding Hay.

Guinea pigs can’t get enough nutrition from fibre when it passes through their gut the first time. To help them get all the nutrients they need, guinea pigs excrete caecotrophs. These are soft, sticky-type droppings that they then re-eat to digest the rest of the vital nutrients.

Guinea pigs can’t make their own vitamin C so they need extra in their diet. Vitamin C is important for healthy skin, joints and blood vessels. Burgess Excel has been specially formulated to have all the vitamins your guinea pigs need, including a protected form of vitamin C. Along with a handful of fresh greens a day, you can make sure they are getting enough vitamin C.

Digestible fibre is moved up an organ called the caecum, which acts like a giant appendix.

Good bacteria in the caecum ferment the fibre to make it easy for your guinea pigs to digest. This is then excreted as sticky droppings, called caecotrophs. Guinea pigs then re-eat the caecotrophs so they can absorb the rest of the essential nutrients when they pass through a second time.


Indigestible fibre is moved through their digestive system and excreted as separate, round, hard droppings. This type of fibre keeps the digestive system moving and your guinea pigs’ appetites stimulated.


Beneficial fibre

If guinea pigs don’t get the right amounts of both digestible and indigestible fibre, it can rapidly lead to serious health problems. At Excel, we call the correct ratio of these two types of fibre ‘Beneficial Fibre’.

Sticking to The Excel Feeding Plan will ensure your guinea pigs get the right amounts of fibre in their diet. The Excel Feeding Plan was developed in conjunction with one of the world’s leading small-animal vets, to provide a perfect daily balance of fibre and nutrition.
