Is illinois tick trefoil safe for cats and dogs?
Yes — illinois tick trefoil is listed by the ASPCA as non-toxic to cats and dogs. It is one of the safer picks for a home where pets share the floor space. 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. Desmodium illinoense is not listed by the ASPCA as toxic to cats or dogs; like other Desmodium species the sticky barbed seed pods (loments) can adhere to pet fur, causing matting and localised skin irritation if not removed.

What happens if a pet eats illinois tick trefoil?
Because illinois tick trefoil 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 illinois tick trefoil
- Remove any plant material from your pet's mouth and move illinois tick trefoil 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 illinois tick trefoil to the appointment so it can be treated correctly.
