Is grassy arrowhead safe for cats and dogs?
Yes — grassy arrowhead 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. Sagittaria species are not listed as toxic by the ASPCA. The genus belongs to Alismataceae and has no known toxic principle reported for dogs or cats. The tubers are traditionally eaten by humans. Exercise routine caution with any water plant around pets near open water.
| Pet | Toxic? | Per ASPCA |

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