Mountain Laurel vs. Sheep Laurel: which is safe for cats and dogs?

Mountain Laurel and Sheep Laurel are frequently compared because both belong to the Kalmia genus and share similar evergreen characteristics and showy, cup-shaped flowers. It is vital for pet owners to understand that both plants are highly toxic to cats and dogs. They contain grayanotoxins, which can cause severe systemic poisoning and potentially fatal reactions if ingested. Because both Mountain Laurel and Sheep Laurel pose significant risks to your pets, neither plant is considered safe to keep in a home or garden accessible to animals. If you suspect your cat or dog has consumed any part of either shrub, you must seek emergency veterinary care immediately.
