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

Bog Laurel and Mountain Laurel are frequently compared because they both belong to the Kalmia genus, sharing similar physical characteristics and the same dangerous chemical profile. It is vital for pet owners to understand that both plants are highly toxic to cats and dogs. Both shrubs contain potent grayanotoxins, which can cause severe, life-threatening systemic illness if any part of the plant is ingested. Because the risk of poisoning is extreme for both species, these plants should be kept entirely out of reach of your pets. If you suspect your cat or dog has consumed any portion of either plant, you must seek immediate veterinary care.
