Parsley, curly parsley or garden parsley is a species native to the central Mediterranean region and has been naturalised elsewhere in Europe. It is a widely cultivated herb, spice and vegetable.
It is widely used as a garnish and is also widely used I. European, Middle Eastern and american cuisine.
So can rabbits eat parsley at all?
Lets take a look at their nutritional data in particular their calcium, sugar, phosphorus, acidic, fibre, fat and sodium content is most pertinent as far as piggies are concerned.
As you can see parsley contains a lot of phosphorus, calcium, is very acidic, and contains a hint of sugar, fat and fibre.
This means that rabbits cannot eat parsley. There is too much acidic, calcium and phosphorus content which is bad for them and it will make them ill if they eat it.
If they nibble at it they should be fine but anything more that that is not good.
