The Ultimate Guide to the Best Guinea Pig Foods for Optimal Health and Happiness

Guinea pigs, or cavies, are quiet and small, making them ideal pets for both adults and children. As long as their needs are met, they are easy to care for. It is important to note that their diet plays a crucial role in their health and well-being. Cheri Schubert, a guinea pig breeder and former Registered Veterinary Technician, emphasizes the importance of selecting the right food for your pet. Guinea pigs are herbivores with continuously growing teeth and no ability to produce their own vitamin C, so a balanced diet must be meat-free, promote healthy teeth, and include vitamin C. Failing to provide a proper diet can lead to illness, weakness, and a shortened lifespan. Our experts have narrowed down the top guinea pig food choices to help you make the best decision for your pet.

  • What human foods can I give my guinea pig?
  • Several human foods can be offered to guinea pigs as treats. Schubert notes that Cheerios and quick plain rolled oats are popular options, along with vegetables that are high in vitamin C and some fruits. Bell peppers, kale, leafy lettuce, green beans, parsley, cilantro, strawberry tops, and cucumbers are great vegetable options. Be sure to limit starchy vegetables like sweet potatoes and carrots, and avoid gas-producing vegetables like cabbage and onions.
  • Can guinea pigs eat rabbit food?
  • “Guinea pigs can be fed rabbit food on a very limited basis,” says Schubert. Rabbit food lacks the nutritional components, primarily adequate vitamin C, that guinea pigs need, so it should never be fed to a guinea pig long term. If you absolutely cannot find guinea pig food or are running low and can only find rabbit pellets, you can temporarily mix your rabbit and guinea pig pellets or feed the rabbit pellets until you can get more guinea pig pellets. Vitamin C deficiency is a serious problem and will negatively affect guinea pigs that don’t get adequate amounts in their diet.
  • Can guinea pigs eat any other type of pet food?
  • With the exception of feeding rabbit pellets for a very temporary time, Schubert says, “I would not recommend any other pet foods for a guinea pig. Many of the other foods contain things that guinea pigs shouldn’t eat.”
