Rabbit in buttercups

Buttercups are on many lists of poisonous plants because they can contain an irritant that can cause dermatitis in humans that handle buttercups and salivation, oral ulceration and gastrointestinal irritation in animals that eat them. Rabbits can eat small, young leaves that are growing in pastureland without ill effects. The mature leaves, tall plants and flowers are unpalatable, so they do not eat them. There are no reports of buttercup toxicity in rabbits.
