Are lithops safe for cats and dogs?
Lithops · Succulent
Non-toxic to cats and dogs
Confirmed at genus level for Lithops, so the strangest thing on the windowsill is also among the safest things on it.
Source: ASPCA Toxic and Non-Toxic Plants, at genus level.
Nothing to worry about here. Lithops, the succulents sold as living stones, appear on the ASPCA's non-toxic list for cats and dogs, and the catalogue records that at the level of the genus rather than one named species. They are also the least interesting plant in the house to an animal, being the size of a pebble, hard to the touch and hidden in gravel. The reason to read on is not the pets, it is that the usual way a lithops dies is being watered like a normal plant.
Worth knowing anyway
A plant can be free of poison and still make a dog sick if enough of it goes down, so volume is the only real risk from the lithops itself. The pot is the more sensible thing to think about. They are grown in coarse grit and they look like the stones packed around them, so a puppy that hoovers up gravel should not be left alone with one.
Living with one
A lithops needs the brightest windowsill you own and very little else, which puts it in direct competition with the cat for the sunny end of the desk. It is the small desert succulent to buy instead of a panda plant or a Flaming Katy, both of which the ASPCA list records as toxic at moderate severity. The catalogue schedules water around every 21 days and stretches that further in winter. When you cannot decide whether it needs watering, it does not.

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
Are all living stones safe, or just some species?
The catalogue confirms the genus Lithops rather than a single species, so the answer covers the pebble-shaped plants sold under that name. Anything else in the same tray is a separate question. Elephant bush, often labelled dwarf jade, sits outside the ASPCA list altogether and is recorded as unlisted, which means nobody has confirmed it either way and it should not be read as a quiet yes.
How often do lithops actually need watering?
Less than you think. The catalogue works to around every 21 days and pulls back further in the cold months, in a mix that is mostly grit and a spot with full sun. Humidity of 20 to 40 per cent suits them, which is close to what a centrally heated room already is. A wrinkled lithops recovers from a drink. A soft, split one that has been watered on a weekly rota does not.
My dog nosed the pot over and ate one. What should I do?
There is no poison in the plant to act on. Watch for vomiting, which comes from the quantity of plant material rather than anything in the species, and ring your vet or an animal poison line if it repeats or the dog seems unwell. Think about the grit as well, since a mouthful of top dressing is the part of that pot most likely to cause trouble.
Is the app any use for a plant watered this rarely?
That is where a reminder earns its keep, because a 21 day gap is exactly the sort of thing that gets forgotten or done twice. Schedules start from the catalogue interval, then adapt to the daylight where you live and to what you actually log, so a lithops in Lisbon and one in a Scottish winter do not get the same rota.
