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

Bog Laurel and Sheep Laurel are frequently compared because both belong to the Kalmia genus and share similar growth habits and toxic properties. It is crucial for pet owners to understand that both plants are highly toxic to cats and dogs. They contain potent grayanotoxins, which can cause severe systemic illness and life-threatening complications if ingested by your animals. Because there is no safe variety between these two, both Bog Laurel and Sheep Laurel should be kept entirely out of reach of your pets. If you suspect your cat or dog has consumed any part of either shrub, you must seek emergency veterinary care immediately.
