Is tansy toxic to rabbits?

Q: Is tansy toxic to rabbits?

Yes, Tansy is toxic to rabbits. All parts hold a strong oil rich in thujone, a nerve toxin that can trigger seizures, and the plant can also cause miscarriage in pregnant animals. It is bitter, so poisonings are uncommon but serious: belly pain, a weak fast pulse and violent spasms in larger amounts. Source: House Rabbit Society.
