What to do if your cat eats it

No action needed. A cat that bites one open may get nothing worse than a mouthful of gel-like leaf pulp.

Common questions

Can my cat eat the whole living stone?

There is no toxicity, but Lithops are small and slow-growing — one cat incident can end the plant. Keep them in a closed terrarium or on a high shelf if your cat digs in pots.

Do living stones look like anything toxic?

Not really — their mimicry targets are stones, not plants. The succulent look-alikes to verify are aloe (toxic latex) and Euphorbias (irritating sap); Lithops itself is safe.
