Can guinea pigs eat rabbit food?
Guinea pigs and rabbits eat a very similar diet, but we must remember that these are two different species with their own unique nutritional requirements.
Both rabbits and guinea pigs are natural grazers, so they like (and need) to be nibbling on food (grasses and herbs in their natural state).
At the top of the differences in nutritional requirements we need to cater to for guinea pigs in captivity, compared with rabbits, is their need for a good source of Vitamin C on a regular basis.
Guinea pig food that you buy in the form of pellets contains the required amount of vitamin C (at least, the good foods. And another reason to avoid low quality mixes).
So guinea pigs should not be fed rabbit food as it will be lacking in some required nutrients. Rabbits on the other hand can generally eat guinea pig food without these particular issues.
With the options we have for purchasing quality guinea pig commercial foods and using them as part of an overall balanced diet, there’s no need to feed rabbit food and put a guinea pig at risk of malnutrition and in particular, vitamin C deficiency.
