What should I do if my cat ate Wisteria?

Remove your cat from the plant and any remaining seeds or pods. Pet Poison Helpline is clear that there is no safe way to induce vomiting at home in cats and that hydrogen peroxide should never be given to cats. Call Pet Poison Helpline (855-764-7661) or ASPCA Animal Poison Control (888-426-4435) before attempting any home treatment. Call immediately. Even a single seed or pod warrants a phone call to your vet or Pet Poison Helpline (855-764-7661) or ASPCA Animal Poison Control (888-426-4435). Don't wait for symptoms — by the time bloody vomiting, tremors, or depression appear, your cat needs urgent care.

What should I do if my dog ate Wisteria?

Remove any remaining seeds, pods, or plant material from your dog's mouth and reach. Pet Poison Helpline advises against giving hydrogen peroxide or attempting to induce vomiting without first speaking to a poison-control specialist — even though it's sometimes used in dogs, the dose and timing matter. Call Pet Poison Helpline (855-764-7661) or ASPCA Animal Poison Control (888-426-4435) before any home treatment. Call immediately. Even one or two seed pods can be enough to warrant veterinary care — phone your vet, Pet Poison Helpline (855-764-7661), or ASPCA Animal Poison Control (888-426-4435) before symptoms escalate. Bloody vomiting, lethargy, or persistent diarrhea require in-clinic care, not phone advice.
