Is Sempervivum heuffelii toxic to cats?

No — sempervivum heuffelii 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 ASPCA lists 'Hens and Chickens' as non-toxic to cats and dogs, and houseleeks (Sempervivum) are widely regarded as non-toxic; note the ASPCA's 'Hens and Chickens' entry is botanically Echeveria elegans, and Sempervivum heuffelii is not individually listed under its own name. Considered pet-safe, with at most mild stomach upset if eaten.

Yes — the ASPCA lists sempervivum heuffelii 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: Sempervivum heuffelii is non-toxic to dogs as well. See the full sempervivum heuffelii pet-safety guide for both species.
