Is Goat's Horn Cactus toxic to cats?

No — goat's horn cactus is listed by the ASPCA as non-toxic to cats. It is a sensible choice for a home with a cat; a curious nibble will not poison them, though no plant is meant to be eaten. The Cactaceae genus Astrophytum is not individually named on the ASPCA list, but the ASPCA records no toxic principles for cacti, and the closely related Bishop's Cap (Astrophytum myriostigma) is documented as non-toxic to cats and dogs. The real hazard is mechanical: the long, stiff spines can injure a curious pet's mouth or paws, so site it out of reach.

Yes — the ASPCA lists goat's horn cactus as non-toxic to cats and dogs. A cat that chews a large amount of any foliage can still get a mild, brief stomach upset, so discourage grazing, but it will not be poisoned.

The ASPCA classification Growli uses applies to both cats and dogs: Goat's Horn Cactus is non-toxic to dogs as well. See the full goat's horn cactus pet-safety guide for both species.
