Safety status
What this means for your cat
Cats: fetterbush is in the same Ericaceae family as rhododendron and mountain laurel, and it carries the same family poison — grayanotoxins. The Merck Veterinary Manual notes these compounds bind sodium channels and disturb nerve, muscle, and especially cardiac tissue, so even a small amount of chewed leaf in a cat is taken seriously.
What to watch for
Expect drooling, repeated vomiting, and diarrhoea first. Then watch for weakness or wobbly gait, a slow or irregular heartbeat, and depression. All parts of the plant are toxic — nectar, flowers, leaves, and stems are of greatest concern (Merck).
Time window
Per the Merck Veterinary Manual, clinical signs from grayanotoxin-containing plants typically develop within 1–4 hours of ingestion, occasionally as long as 12 hours.
When to call the vet
Call immediately. Any suspected ingestion of fetterbush by a cat is a vet visit, not a watch-and-wait — grayanotoxins can affect the heart, and cats are small enough that a few leaves can matter.
