Is Split Rock toxic to cats?

No — split rock 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. Pleiospilos nelii is not individually listed in the ASPCA toxic and non-toxic plant database, but its genus member Pleiospilos bolusii (Living Rock Cactus, family Aizoaceae) is listed by the ASPCA as non-toxic to dogs, cats, and horses, with no Pleiospilos species flagged as toxic. It is therefore considered pet-safe; still discourage chewing and verify with your vet if a pet ingests any.

Yes — the ASPCA lists split rock 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: Split Rock is non-toxic to dogs as well. See the full split rock pet-safety guide for both species.
