Is many-leaved monanthes safe for cats and dogs?
Yes — the ASPCA lists many-leaved monanthes on the non-toxic side of its cat-and-dog reference. A chewed leaf still isn't dinner, but it won't trigger a poisoning. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. Monanthes is a member of Crassulaceae native to Macaronesia. It is not individually listed by the ASPCA. Unlike toxic Crassulaceae genera (Crassula, Kalanchoe), no toxic compounds have been identified for Monanthes. Considered low-risk, though as with any plant, ingestion in large quantity by a pet may cause mild stomach upset.
| Pet | Toxic? | Per ASPCA |

| Cats | No | Pet-safe |
| Dogs | No | Pet-safe |
What happens if a pet eats many-leaved monanthes?
Because many-leaved monanthes is non-toxic, a curious nibble will not poison a cat or dog. That said, no plant is meant to be eaten: a large quantity of any foliage can still cause mild, short-lived stomach upset or vomiting simply through fibre and volume. Persistent vomiting, diarrhoea, or lethargy after eating any plant is always worth a call to your vet, because the reaction may be to soil, fertiliser, or a pesticide rather than the plant itself.
What to do if your pet ate many-leaved monanthes
- Remove any plant material from your pet's mouth and move many-leaved monanthes out of reach.
- Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
- Do not induce vomiting unless a vet or poison-control specialist instructs you to.
- Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
- Bring a leaf or photo of many-leaved monanthes to the appointment so it can be treated correctly.
