Guinea pigs are herbivores, which means they should primarily eat a diet of fresh vegetables to ensure they get all the nutrients they need with unlimited access to hay. Hay should make up the majority of their diet, as it helps to keep their teeth trimmed and provides important nutrients.
They also need a source of vitamin C, as they are unable to synthesise it on their own. This can be provided through pellets/nuggets or by including vitamin C-rich foods in their diet, such as bell peppers, broccoli, and leafy greens. Fruit is a good source of vitamins and can be offered as an occasional treat, but it should not make up a significant portion of their diet as it is high in sugar.
It's also important to provide your guinea pig with a consistent source of clean, fresh water via bottle or a heavy, tipped-proof bowl.
All information on this site is sourced and collated from other online resources. We recommend Guinea Pig owners carry out independent research and take caution when making decisions in the interest of their pet. It's a good idea to consult with a veterinarian or a knowledgeable breeder to determine the specific dietary needs of your guinea pig. Every guinea pig is different, and the specific diet that works best for one guinea pig may not be ideal for another.
We want this food guide to be useful to all Guinea Pig owners and need the help of the community to achieve that. If you would like us to add a food item or If there is information in the database which you do not feel is correct or perhaps requires more information or further context, please contact us at firstname.lastname@example.org and we will be happy to make amends.
