FAQ
My dog chewed a haworthia — should I worry?
No toxin is on record. The ASPCA's Haworthia entry covers the genus (Haworthia species, "Many cultivars") and reads "Non-Toxic to Dogs, Non-Toxic to Cats," with toxic principles "Non-toxic." Pet Poison Helpline names Haworthia among succulent varieties that "are non-toxic to pets." If your dog seems unwell afterwards, call your vet and mention what was eaten.
Does this cover zebra haworthia, pearl plant and other haworthias?
Yes, as the ASPCA grades them. Its genus entry lists Haworthia species as non-toxic, and its separate species entries agree: Zebra Haworthia (Haworthia fasciata), Little Zebra Plant (Haworthia subfasciata), and Pearl Plant and Pearly Dots (both Haworthia margaritifera) each read "Non-Toxic to Dogs, Non-Toxic to Cats." So a plant sold under any of those names, with Haworthia on the tag, falls under this S0 verdict. If the tag names a different genus, look that plant up separately — a lookalike rosette is not automatically a haworthia.
Is zebra haworthia the same as the "zebra plant"?
No — several different plants share the nickname, and every ASPCA entry that uses it is non-toxic. Zebra haworthia is a Haworthia, the striped rosette succulent on this page: the ASPCA lists Haworthia species ("Many cultivars") as non-toxic to dogs and cats, and Pet Poison Helpline names Haworthia among succulents that are non-toxic to pets — S0 Safe. The plant sold as zebra plant is usually Aphelandra squarrosa, a leafy houseplant with white-veined leaves, which has its own record: S0 Safe on our zebra plant page, where the ASPCA lists it as non-toxic to cats, dogs, and horses. A calathea can also be sold as zebra plant (our calathea page, also S0 Safe), and the ASPCA's Pheasant Plant entry (Cryptanthus zonatus), which lists Zebra Plant as another name, reads "Non-Toxic to Dogs, Non-Toxic to Cats, Non-Toxic to Horses"; we have not graded that plant ourselves. Same nickname, different plants — check the scientific name on the tag.
Haworthia is in the lily family — isn't lily deadly to cats?
Different plants entirely, despite the old family label. The kidney-failure danger belongs to true lilies (Lilium and Hemerocallis) — cut-flower lilies, not this little striped rosette. The ASPCA lists Haworthia ("Many cultivars") as "Non-Toxic to Cats," and Pet Poison Helpline names Haworthia among succulent varieties that "are non-toxic to pets." No kidney risk, no toxin on record. If what you have is a bouquet lily rather than a potted rosette, that's a genuine emergency — see our lily page. A chewed haworthia needs nothing but sympathy for the plant.
