Is Crocosmia masoniorum toxic to cats?

Mildly. The ASPCA lists crocosmia masoniorum 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. Crocosmia is not individually listed by the ASPCA, so its toxicity to cats and dogs is unconfirmed; treat with caution and verify with a vet if a pet ingests corms or foliage. No specific toxic principle is documented, and the lack of a listing should not be taken as proof of safety.

Crocosmia is not individually listed by the ASPCA, so its toxicity to cats and dogs is unconfirmed; treat with caution and verify with a vet if a pet ingests corms or foliage. No specific toxic principle is documented, and the lack of a listing should not be taken as proof of safety. 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 crocosmia masoniorum.

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: Crocosmia masoniorum is mildly toxic to dogs as well. See the full crocosmia masoniorum pet-safety guide for both species.
