What should I do if my cat ate Mayweed?

If your cat brushed against the plant, rinse the affected fur with cool water and mild pet shampoo to remove residue. For ingestion, remove plant material from the mouth and call your vet. Do not induce vomiting at home. Call your vet or ASPCA APCC (1-888-426-4435) if your cat shows persistent vomiting, refuses food for more than a meal or two, or develops a skin reaction that's spreading or oozing. Get in immediately for any allergic-type swelling.

What should I do if my dog ate Mayweed?

Call your vet or the ASPCA Animal Poison Control Center (888-426-4435) if your dog has eaten more than a nibble, is vomiting repeatedly, has visible skin irritation that isn't improving, or stops eating. Routine brush-by contact with mild itching can usually be managed at home, but escalate if symptoms worsen.
