What this means for your cat

Cats — toxic. ASPCA lists wahoo (Euonymus) as toxic to cats; the plant contains alkaloids and cardenolides — cardenolides being the same family of compounds in foxglove that disrupt heart rhythm. Outdoor cats roaming gardens or yards with euonymus shrubs are the most likely to encounter it, and ingestion is worth taking seriously even before symptoms appear.

What to watch for

ASPCA lists vomiting, diarrhea, abdominal pain, and weakness; with larger doses, heart-rhythm abnormalities can occur. Watch for lethargy, reluctance to move, and any pale-gum or rapid/irregular pulse changes that suggest cardiac involvement.

Time window

Exact onset and duration are not well documented in the ASPCA listing.

When to call the vet

Call your vet or ASPCA Animal Poison Control (888-426-4435) on suspicion — earlier is better with cardenolide-containing plants. Treat weakness, an unusual heart rate, or repeated vomiting as urgent.
