What else to know

ASPCA’s page adds that the gel itself is considered edible. The problem is the rest of the leaf.

ASPCA also lists Barbados aloe (Aloe barbadensis) as toxic to cats and dogs.

Look-alikes

  • Haworthia: non-toxic to cats, non-toxic to dogs (ASPCA). Small rosettes of thick leaves, often striped or patterned, that stay 2 to 12 inches tall. Aloe vera grows to 2 or 3 feet.

Care basics

Light: Full sun to part shade; indoors, give it your brightest spot.

Soil and water: Let the soil dry out completely between waterings, and water less in winter. Use very well-drained succulent mix in a pot with several drainage holes; NC State says clay works best.
