  1. 5.0 out of 5 stars

    "Works Great"

    I wouldnt use anything else on my cats. Jeffers' prices are very reasonable and shipping is fast. Advantage kills fleas reliably and lasts.

  2. 5.0 out of 5 stars

    "Reliably Consistant To Kill Fleas"

    I wouldnt use anything else to treat my flea problem. Where I live, fleas are tough to kill and a year-round problem, but Advantage works and is easy to spply.

  3. 4.0 out of 5 stars

    "Great Product"

    Advantage works wonders on my cat to keep fleas dead for a month. Even in the hard late summer months. HOWEVER, if you decide to order this DO NOT USE THE FREE SHIPPING I had to wait for over a week for a small package to travel all over the country just to go from Dothan to Ebro. Worst shipping plan ever! Pay for regular UPS Ground. 5 Stars for the product Minus 1 for poor shipping and Customer Service.

    "Works Great"

    Frontline does not work on my cats to kill and repel fleas, and this is the cheapest flea treatment that I can find that works. Period. I have multiple cats and price is important, and this stuff works.

    "Advantage For Me!"

    Got a severe flea infestation, tried Frontline on my 4 cats for 8 months straight, and I was at my wit's end. I resorted to giving my cats baths, and it is so difficult to do! <g> Switched to Advantage and within 2 wks, all fleas have disappeared.

    "just the best...."

    On a farm with 5 dogs and lots of cats, Advantage works within hours and remains working well past a month for me, for years now. I was disappointed with Frontline in comparison, which took a few days and lasted only about 2 1/2 weeks...went right back to Advantage!

  7. 5.0 out of 5 stars

    "No Fleas"

    Have used for 5 years on cats/dogs and has cured my flea problem. Like the other viewer said, unlike Frontline which worked for a couple of years and then quit working.

  8. 5.0 out of 5 stars

    "Works great"

    This product has kept our animals free of ticks and fleas for as long as we used it, unlike frontline
