Is Aloe toxic to cats?
Aloe (Aloe vera) is toxic to cats. The agent is saponins, anthraquinones.
ASPCA Animal Poison Control, 24 hours: (888) 426-4435 (a consultation fee may apply), or call your own vet. Take a piece of the plant with you.
Signs that need a vet the same day whatever the plant: repeated vomiting, drooling that will not stop, swelling of the mouth or face, trouble breathing or swallowing, collapse, or a seizure.
What it does, and why
Aloe contains saponins, anthraquinones. Saponins are soap-like compounds that irritate the gut lining. The result is stomach upset rather than organ damage, and it usually resolves once the plant material is out.
Signs to watch for
Vomiting, lethargy, diarrhea.
The clear inner gel is considered edible; the latex just under the skin is the toxic part.
How likely is it, really
Most cases are a chewed leaf rather than a meal. The dose matters: a nibble and a swallowed stem are different events. Volume, and how long ago, are the two things the vet will ask.
Keeping the plant anyway
Height alone does not work with a cat — a cat treats a high shelf as a destination. What actually helps: a room the cat does not have unsupervised access to, a hanging position with no adjacent launch point, and clearing fallen leaves the same day, since a dropped leaf on the floor is the usual culprit. A pot of cat grass elsewhere in the room redirects the urge to chew far better than deterrent sprays do.
Is it toxic to people?
No meaningful hazard to people from handling Aloe. Ordinary care with small children still applies — anything chewed in quantity can cause a stomach ache.
