Is Haussknecht's Rosularia toxic to cats?

No — haussknecht's rosularia 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. Rosularia is not individually listed by the ASPCA. The genus belongs to Crassulaceae but is closely allied to Sempervivum, which is widely cited as non-toxic to cats and dogs. No toxic compounds are documented for Rosularia. The genus does not share the bufadienolide cardiac toxins found in Cotyledon, Tylecodon, or Kalanchoe. Classified as pet-safe based on absence of known toxic principles and taxonomic proximity to Sempervivum, though individual ASPCA listing is absent.

Yes — the ASPCA lists haussknecht's rosularia 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: Haussknecht's Rosularia is non-toxic to dogs as well. See the full haussknecht's rosularia pet-safety guide for both species.
