Is Sagittaria subulata toxic to cats?

Mildly. The ASPCA lists sagittaria subulata as mildly toxic to cats — a chewing cat typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. Sagittaria subulata is not individually listed on the ASPCA Toxic and Non-Toxic Plants database, and the genus Sagittaria has no established ASPCA classification; hobbyist sources call it pet-safe but this lacks authoritative grounding. Treat with caution and verify with a vet before relying on it as non-toxic around cats, dogs, or fish-tank-grazing pets.

Treat with caution and verify with a vet before relying on it as non-toxic around cats, dogs, or fish-tank-grazing pets. Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your cat has had access to sagittaria subulata.

Stay calm. Remove any plant from your cat's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.

The ASPCA classification Growli uses applies to both cats and dogs: Sagittaria subulata is mildly toxic to dogs as well. See the full sagittaria subulata pet-safety guide for both species.
