Rabbits can eat parsley (curly or flat) as a delicious addition to their varied diet, as it is high in vitamin C and can contribute to their minimum of 5 leafy greens. However, it should be given in moderation as it contains oxalic acid, which may contribute to the formation of bladder stones, although most of the oxalate found in urine is produced by the body, rather than absorbed from food.
