I have 2 cats. Usually we use Advantage for 30 days+ with no problems, but the pet shop was out last time. We bought Frontline and applied it. For 2 weeks the cats were fine, but now the fleas are back and worse than ever. I have 1 tube of Frontline left, and I’m wondering if I should split it between the cats, for at least some relief, and wait 2 weeks to apply Advantage, or if I should just apply Advantage now. I desperately need an answer– these fleas are getting to me, too!
