Is Aloe Barbadensis Toxic to Cats?

Yes — Aloe Barbadensis is mildly toxic to cats

Aloe barbadensis is the same species as Aloe vera. The clear gel is minimally toxic, but the yellow latex layer beneath the skin contains anthraquinones that act as a strong laxative in pets.

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

Vomiting
Diarrhea
Lethargy
