Safety status
What this means for your cat
Cats nibbling hosta leaves are exposed to saponins, which mainly irritate the GI tract. The ASPCA classifies it as toxic, but a large amount needs to be eaten for severe effects, and fatalities in cats are essentially unheard of — most cats recover fully after the initial illness.
What to watch for
Vomiting and diarrhea are most common, followed by depression, lethargy, and loss of appetite. More severe cases involve bloody stools or vomiting that lasts more than a day; the severity tends to track how much was eaten.
Time window
ASPCA does not publish exact onset; GI signs typically appear within hours of ingestion and resolve in 24 hours or so with supportive care, though more severe ingestions can persist longer.
When to call the vet
Call your vet or ASPCA Poison Control (888-426-4435) if vomiting is bloody or persists past 24 hours, your cat refuses food for more than a day, or your cat seems markedly lethargic. A single chewed leaf with mild signs usually does not require a visit.
