Is Onzuka Bishop's Cap toxic to cats?

Astrophytum myriostigma 'Onzuka'

Non-toxic to cats

No — onzuka bishop's cap 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. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Astrophytum is not on the ASPCA toxic plant list, and cacti (Cactaceae) are not considered systemically poisonous to cats or dogs. Not individually listed by the ASPCA, so this is a family-level safe rating. Notably this species is spineless, so it carries even less mechanical risk than typical cacti, but it is still not a food plant.
