      Will my cat or dog experience any side effects from using topical flea and tick products?
      Some reaction may occur after using any pesticide product. Generally, if a pet is going to have any sensitivity, it would be a skin irritation at the site of product application. This should not persist for long, but if it lasts for more than a couple of days, or becomes more severe, we recommend you consult your veterinarian as soon as possible.
