My cat ate Green Milkweed — what to do
Step by step
- Take green milkweed away and remove any plant material from your cat's mouth so they cannot eat more.
- Note roughly how much was eaten and when — this helps the vet judge the risk.
- Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
- Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
- Watch for drooling, pawing at the mouth, vomiting, loss of appetite, or lethargy, and bring a leaf or photo to the appointment.
This is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide as well as the plant. When in doubt, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435.
My cat ate green milkweed — FAQ
Is green milkweed poisonous to cats?
Yes — the ASPCA lists Green Milkweed (Asclepias viridis) as toxic to cats. 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.
How serious is it if my cat ate green milkweed?
Green Milkweed is toxic to cats and reactions can be significant, so treat any ingestion as urgent. Call your vet or poison control on (888) 426-4435 straight away rather than waiting to see if symptoms develop.
What symptoms should I watch for?
Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. 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. Any worsening or persistent symptoms warrant an immediate vet visit.
