Is Monstrose Apple Cactus toxic to cats?

No — monstrose apple 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 species Cereus repandus is listed by the ASPCA framework among non-toxic cacti (Cactaceae), aligning with its non-toxic 'Tree Cactus' and 'Night Blooming Cereus' entries for cats, dogs, and horses. Spines, where present, are a mechanical hazard, and eating plant tissue may cause mild GI upset, so site it away from curious pets.

Yes — the ASPCA lists monstrose apple 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: Monstrose Apple Cactus is non-toxic to dogs as well. See the full monstrose apple cactus pet-safety guide for both species.
