Is Aloe Vera Toxic to Cats?

Yes — Aloe Vera is mildly toxic to cats

While Aloe Vera is wonderful for human skin, it's mildly toxic to pets. The saponins and latex cause gastrointestinal upset. Most pets recover without treatment, but the bitter taste usually limits how much they eat.

Symptoms in Cats

If your cat eats Aloe Vera, watch for these symptoms (onset: 6-12 hours):

Vomiting
Diarrhea
Lethargy
Tremors (rare, large ingestion)

What To Do

Monitor at home for mild cases. Offer water. See vet if vomiting persists or lethargy develops.
