Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Drooling, vomiting, diarrhea, and potential lethargy.
Escalation note
Ingestion can cause gastrointestinal distress. Please contact your veterinarian or a pet poison control center immediately if you suspect your cat has consumed this plant.
What to watch for
ASPCA reports photosensitization presenting as sunburn and dermatitis. Watch lightly pigmented or thinly furred areas (nose, ear tips, eyelids) for redness, swelling, blistering, or peeling after possible exposure.
Time window
Specific onset and recovery timing are not documented in the ASPCA listing.
When to call the vet
Call when you see any sunburn-like reaction, blistering, eye irritation, or progressive skin damage following suspected exposure to the plant.
What this means for your cat
Cats: the danger is sun damage, not the GI tract. ASPCA lists furanocoumarins as the toxic principle, and the resulting injury is photosensitization — sunburn-like skin and eye damage triggered when an exposed cat goes outdoors after ingestion or contact.
