As you can see, garden cress contains a noticeable amount of phosphorus, calcium, sugar and is quite acidic.
However, the vitamin c content is fantastic and so on this basis, is really worth considering giving your guinea pig.
However, don’t feed it so regularly because of its phosphorus, calcium, sugar and acidic content.
A small amount, once a week at most, but nothing more than that.
