Cats that bite plum leaves, stems, or a crushed pit are at risk of cyanide poisoning from the plant's cyanogenic glycosides. The flesh of the ripe fruit is not the concern — cats rarely chew open a hard pit. ASPCA flags wilting plant material as especially dangerous.
Vomiting and diarrhea may come first; the cyanide signature to take seriously is difficulty breathing, panting, brick-red gums, dilated pupils, weakness, and collapse (shock).
Cyanide signs can appear within minutes to about an hour of kernel ingestion and progress within hours; mild leaf-only GI signs typically resolve in 24-48 hours with supportive care.
Call immediately if a pit was chewed open or any leaves or wilted plant material were eaten. Any labored breathing, gum-color change, or collapse is a same-minute emergency.
