Safety information
Calming Care is a supplement, not a sedative, and does not cause drowsiness. For animal use only; keep out of reach of children and store in a cool, dry place. If your cat's anxiety is severe or behavior changes suddenly, consult your veterinarian so medical causes can be ruled out.
