Is Cassia Toxic to Cats?
Also known as: Golden Shower Tree, Senna · Cassia spp.
What makes it toxic
Anthraquinone glycosides, the same class of compounds as senna laxatives, plus saponins in the leaves, pods and seeds. They violently stimulate the gut.
Warning signs to watch for
Drooling, vomiting, prolonged watery diarrhea and lethargy within hours. Significant fluid loss can lead to dehydration and collapse in small cats.
What to do if your cat eats it
Remove plant material, offer water and watch for diarrhea. Call your vet the same day; persistent watery diarrhea is a dehydration emergency for a small cat.
Common questions
Are cassia pods dangerous to chew?
Yes, the pods and seeds are among the most concentrated sources of the laxative glycosides. Pods falling from the tree are a common exposure for pets.
Is cassia related to senna laxatives?
Exactly — the active compounds are the same class used in human laxatives, which is why eating the plant overstimulates the bowel so strongly.
