It’s generally safe for guinea pigs to eat parsley if it’s fed to them in moderation. Parsley contains a high amount of calcium and oxalic acid.

Cavies need a lot of calcium for growth and development. However, for baby cavies, it can become an issue.

At this age, they don’t require high amounts of calcium. The high calcium content will lead to kidney problems, bladder stones, and issues with the digestive system.

As for oxalic acid, too much can be fatal for cavies. Oxalic acid leads to kidney stone formation. As a guideline, an adult cavy should not eat more than 50 mg per day of oxalic acid.

To keep the cavies from having health issues, only feed parsley as occasional treats.
