Parsley or garden parsley is native to the central Mediterranean region and is widely cultivated as a herb, spice and a vegetable. It grows as a biennial growing a rosette of tripinnate leaves 10–25 cm long with numerous 1–3 cm leaflets, and a taproot used as a food store over the winter.
It is often used in dishes from around the world and is used as a snack or a vegetable in many soups, stews, and casseroles.
So can chinchillas eat parsley at all?
Lets take a look at its nutritional data, in particular its calcium, sugar, phosphorus, fat, and acidic content are most pertinent to chinchillas.
As you can see parsley contains a lot of phosphorus, calcium, and acidic content.
This means it is not great for chinchillas to eat. If they have a nibble at it, they will be fine but anything more than that will hurt their tummies.
