Review title: Didn't Work
Product review: My veterinarian said I was wasting my money on Frontline. I had used it in the past with good results, so I bought it anyway. It came fast and in regular packaging, but it didn't work, period. We ended up with a full-blown flea infestation. Our vet used Advantage on my cat while he was getting neutered (wearing Frontline) because he had fleas. The fleas started dying off immediately and were gone in 24 hours. I used it on all 4 cats with excellent results. I didn't have to treat my house or yard. A month later, still no fleas.
