Pet ingestion lookup
My cat ate Bog Laurel - what should I do?
Kalmia poliifolia
Potentially toxic
Contact your veterinarian or an animal poison-control resource now, especially if any amount was chewed or swallowed.
Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Drooling, vomiting, diarrhea, abdominal pain, loss of appetite, tremors, and potential cardiac arrhythmias.
Escalation note
This plant is highly toxic. Ingestion of even small amounts can cause severe systemic illness. Contact your veterinarian or an animal poison control center immediately if ingestion is suspected.
First aid at home
Remove any leaves or plant material from your cat's mouth and from their reach, then call the ASPCA Animal Poison Control Center at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661. Don't induce vomiting at home unless poison control or your veterinarian tells you to.
What to watch for
Earliest signs are GI: vomiting and diarrhea. From there watch for weakness and any sign of cardiac involvement — irregular pulse, collapse, or extreme lethargy. The toxic principle disrupts skeletal muscle, cardiac muscle, and nerve function, so cardiac failure is the worst-case progression flagged by ASPCA.
Time window
Specific onset and duration for cats are not given in the cited sources. Treat any known ingestion as time-sensitive given the cardiac risk flagged by ASPCA.
When to call the vet
Call immediately on any known ingestion — bog laurel is in the same toxin class (grayanotoxin) as mountain laurel and rhododendron and can affect the heart. Don't wait for symptoms. Reach the ASPCA Animal Poison Control Center at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661.
What this means for your cat
Bog laurel carries grayanotoxin in every part of the plant, and cats are sensitive to it — the ASPCA lists vomiting, diarrhea, weakness, and cardiac failure as clinical signs. Cats rarely chew on plants in volume, so any actual ingestion of bog laurel leaves should be taken seriously.
