Can Guinea Pigs Eat Cat Food?

What Do Guinea Pigs Eat?

Most guinea pigs are herbivores, meaning that their diet consists of plants. They generally eat hay, pelleted food made specifically for guinea pigs, fresh vegetables and fruits, and occasional treats like dried herbs or root vegetables. In the wild they would also eat grasses and other greenery.

Can Guinea Pigs Eat Cat Food?

Cat food is not recommended as a regular part of a guinea pig’s diet because it is not nutritionally balanced to meet their needs. Additionally, cat foods often contain ingredients that can be harmful to guinea pigs such as too much fat or protein. If you do decide to offer your pet some cat food as an occasional treat, choose one with no artificial colors or flavors and make sure it does not contain any ingredients known to be toxic for guinea pigs like garlic or onion powder.

Some people may mistakenly think that because cats are carnivorous animals they need more protein than herbivores like guinea pigs; this is not the case! As long-term herbivores they actually require less protein than cats do in their diets but higher levels of fiber which cat foods typically lack.


It’s important to remember that most domesticated animals have different nutritional requirements depending on species – what’s good for one animal isn’t necessarily good for another! While it can occasionally be okay to give small amounts of cat food as a treat to your pet guinea pig, it should never replace the healthy plant-based diet required by these adorable critters in order to stay happy and healthy!
