Safety status
What this means for your cat
Sudan grass is listed by the ASPCA as non-toxic to cats — its cyanogenic glycosides and nitrates pose serious risk to horses and livestock, but cats don't typically graze in volumes that cause poisoning. Cats that chew on a few blades may vomit or pass loose stool from the rough fiber.

If a pet has chewed or swallowed plant material and is showing symptoms, contact a veterinarian or poison resource immediately. This product is for structured reference, not diagnosis.
