Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Small mammals (rabbits, guinea pigs, hamsters): No confirmed toxic effects; large ingestion may cause mild temporary digestive upset

Caged birds: No identified toxic risk from small accidental ingestion; monitor for unusual behavior after consumption of large quantities

Confusion Risk

The following plants look similar and may be confused:

Zebra Haworthia Haworthiopsis fasciata

Visually nearly identical with characteristic white striped leaf markings; key difference is H. subfasciata has raised bumps on both leaf surfaces, while H. fasciata only has bumps on the outer leaf surface. Both species are non-toxic.

Dwarf Aloe Aloe juvenna

Small rosette-forming succulent with pointed green leaves frequently mistaken for small Haworthia species; most Aloe species are mildly toxic to pets, unlike H. subfasciata.
