Is Japanese Peperomia toxic to cats?

No — japanese peperomia 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. Peperomia japonica is not individually listed by the ASPCA, but every Peperomia species reviewed by the ASPCA — including P. obtusifolia, P. argyreia, P. caperata, P. griseoargentea, and P. prostrata — is listed as non-toxic to dogs and cats, with no toxic member recorded in the genus. It is treated as pet-safe on that basis; confirm with your vet if a pet ingests any plant material.

Yes — the ASPCA lists japanese peperomia 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: Japanese Peperomia is non-toxic to dogs as well. See the full japanese peperomia pet-safety guide for both species.
