Are haworthias safe for cats and dogs?

Haworthia fasciata · Succulents

Non-toxic to cats and dogs

Cats: Non-toxic Dogs: Non-toxic

Haworthia fasciata is confirmed by species. It is the small striped succulent that is not an aloe, and aloe is the one on the toxic list.

It is safe. Haworthia fasciata, the zebra haworthia, appears on the ASPCA's non-toxic list for cats and dogs, which is the whole reason it is worth knowing apart from aloe. Aloe vera is on the toxic list at moderate severity for both, and the two sit side by side in the same shops in the same size pot. Haworthia stays small and firm with raised white bands across the leaves. Aloe keeps growing, and its leaves are thicker, softer inside and toothed along the edge.

Worth knowing anyway

Non-toxic is a statement about poison and nothing else. A dog that gets through a rosette of water-filled leaves may be sick from the sheer volume, and repeated vomiting means a call to your vet or an animal poison line. One more thing worth knowing: zebra plant is also a common name for a calathea that the ASPCA list does not cover, recorded as unlisted rather than safe, so buy on the botanical name.

Living with one

A haworthia is a desk plant. It wants bright light without the direct midday sun aloe enjoys, so it works on a shelf near the window rather than on the sill, which also keeps it out of the way of a cat that patrols glass. Watering is the easy part, scheduled around every 16 days in the catalogue and less again in winter. Killing one takes effort, and that effort is almost always a watering can.

Let the app remember this for you

Kounts Care holds your plants and your pets in one household, so it checks every new plant against the cats and dogs you actually own, names them in the warning, and runs the check again over your existing plants the day a new animal arrives. Toxicity warnings are free at every tier.

Questions people actually ask

How do I tell a haworthia from an aloe?

Size and texture do most of it. A haworthia stays in a small pot and its leaves are hard and marked with raised white ridges on the outside. An aloe grows on, with longer leaves that give slightly when squeezed and small teeth along the edges. If the label says Aloe, take it seriously: the ASPCA list records aloe as toxic at moderate severity for cats and dogs.

How often should a haworthia be watered?

Around every 16 days on the catalogue schedule, and less than that in winter. The plant stores its own water, so the failure mode is a generous owner rather than a forgetful one. It wants bright light without direct scorching sun, sitting in a mix that drains and a pot with a hole in the bottom. A haworthia that has sat in wet compost tends to come apart at the base with no warning.

Are all haworthias non-toxic or only the zebra one?

The confirmed entry is Haworthia fasciata, the zebra haworthia, which also turns up labelled Haworthiopsis or zebra cactus. Those are names for one plant rather than three different ones. Close relatives are a separate question: gasteria, sold as ox tongue, is not covered by the ASPCA list, so it is recorded as unlisted, and that is an absence of information rather than a clean bill of health.

We are getting a kitten. Does the app recheck the plants we own?

Yes. Adding a cat or a dog to the household re-runs the check across every plant already on your profile, rather than only applying to what you add next. Anything toxic to the new animal is flagged there and then, and a severe result comes up as a full-screen warning. The toxicity check is free at every tier, so nothing about it depends on what you are paying.
