Is Green Milkweed toxic to cats?

Yes — green milkweed is toxic to cats according to the ASPCA. Keep it well away from any cat that chews plants; reactions can be significant. As an Asclepias species, Green Milkweed contains cardenolide cardiac glycosides and milky latex resinoids, consistent with the ASPCA's classification of Asclepias (milkweeds) as toxic to dogs and cats. All plant parts should be considered toxic. Symptoms of ingestion include vomiting, drooling, weakness, and cardiac effects. Seek veterinary attention if a pet ingests any part.

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 green milkweed.

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: Green Milkweed is toxic to dogs as well. See the full green milkweed pet-safety guide for both species.
