Cats that chew Autograph Tree are exposed to the plant's terpenes — the resinous oils responsible for clusia's sticky sap. ASPCA classifies it as toxic to cats; most cases are limited to digestive upset, but the fruit is the most concentrated source of the toxin and is the part most likely to push beyond a stomach ache.
Drooling and a stretch of mouth-pawing usually come first, followed by vomiting and a sluggish, off-food cat. A cat that ate fruit may show more pronounced GI signs; in heavier ingestions, wobbliness or tremors are a flag because terpenes can affect the central nervous system in larger doses.
Exact timing is not well documented; mild GI signs typically appear within a few hours and resolve within 24 hours with supportive care.
Call your vet or ASPCA Poison Control at (888) 426-4435 if vomiting doesn't stop after the first episode, your cat refuses food for more than one meal, or you saw fruit get eaten. Wobbliness, tremors, or yellow-tinged gums warrant an immediate visit.
