you can’t know if your cat is allergic to any other product without applying the
product. Advantage is a good product with good results but it can cause a few
very rare occasions skin reactions such as hair loss, redness, itching and skin
lesions may occur. Agitation has also been reported. Excessive salivation and
nervous signs such as in-coordination, disorientation, agitation, tremors and
depression have been reported exceptionally in cats and dogs.
dogs no adverse clinical signs were produced by either individual doses of up to
200 mg/kg body weight (five to eight times the therapeutic dose), daily
treatments at 100 mg/kg body weight for five consecutive days or weekly
treatments at five times the maximum dose rate for eight consecutive weeks.
cats, no adverse clinical signs
were produced using doses of five times the therapeutic level for eight
My advice is to
not change the product if you have good result with Frontline because it may
cause side effects.
