What should I do if my cat ate Shamrock Plant?

Do not induce vomiting at home — Pet Poison Helpline specifically warns against that for cats. Remove any remaining plant material and rinse fragments from the mouth and paws. Then contact your vet or Pet Poison Helpline before doing anything else. Call right away if you saw your cat eat more than a leaf or two, or if you see weakness, tremors, repeated vomiting, or any blood in vomit or stool. For a small nibble with no symptoms, call for guidance — it's usually mild but worth a check, especially in kittens or older cats.

What should I do if my dog ate Shamrock Plant?

Do not induce vomiting unless your vet or Pet Poison Helpline tells you to. Clear any remaining plant from the mouth and rinse fragments off the paws and muzzle. Then call for guidance before any further home treatment. Call immediately if your dog ate more than a couple of leaves, if you see tremors, weakness, or repeated vomiting, or if there's blood in vomit or stool. For a small nibble in an otherwise healthy adult dog, call for advice; small breeds and puppies should be seen sooner.
