Tarragon is toxic to cats. The ASPCA lists it on its toxic-plant list with essential oils as the toxic principle, and reactions in cats are typically limited to mild stomach upset rather than systemic poisoning. A curious nibble is rarely an emergency, but the herb is not safe to leave within reach.
Watch for mild vomiting, soft stool or diarrhea, drooling/hypersalivation, and reduced appetite. Effects are usually mild; anything beyond one or two transient bouts of vomiting, or persistent disinterest in food, is the threshold for concern.
Exact onset and duration are not specified in the ASPCA entry. For comparable essential-oil herb ingestions, mild GI signs typically appear within a few hours and resolve in 24–48 hours with supportive care.
Call your vet if vomiting or diarrhea continues past a few hours, if your cat refuses food or water for more than 12 hours, or if you see lethargy, weakness, or any sign beyond a transient stomach upset. ASPCA Poison Control: (888) 426-4435.
