Is spreading spike moss safe for cats and dogs?
Yes — the ASPCA lists spreading spike moss 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. Not individually listed by the ASPCA. Selaginella (spike mosses) are not true ferns or flowering plants, but are broadly considered non-toxic to cats and dogs and do not belong to any toxic plant family.

| Dogs | No | Pet-safe |
What happens if a pet eats spreading spike moss?
Because spreading spike moss 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 spreading spike moss
- Remove any plant material from your pet's mouth and move spreading spike moss 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 spreading spike moss to the appointment so it can be treated correctly.
