Haworthia
Haworthiopsis attenuata
Haworthia (Haworthiopsis attenuata) is considered non-toxic to cats. This assessment uses the published Haworthia group listing and the documented older name Haworthia attenuata. Check the botanical label before buying: other plants sold as zebra plants may be different species.
Non-toxic does not mean edible. Eating plant material can still upset your cat’s stomach.
What this guide covers: This guide covers Haworthiopsis attenuata, formerly named Haworthia attenuata. The safety evidence is a genus-level assessment applied to this documented member, not a cat-specific experiment on this species. It does not identify Haworthiopsis fasciata, unrelated zebra plants or unidentified hybrids.

Sources & review
- Haworthia — published group assessment ↗ASPCA Poison Control · Accessed
Listed by the source as Haworthia species. ASPCA explicitly assesses Haworthia species as non-toxic to cats. Kew treats Haworthia attenuata as a synonym of Haworthiopsis attenuata. The former is a documented historical member of the assessed source genus. This narrows the published group assessment to the master species; it does not claim a species-specific experiment, genus/species equivalence, coverage of unidentified hybrids, or synonymy with fasciata.
