Frontline is a wonderful flea and tick prevention tool! Once a month I administer Frontline to my two cats, Cassie and PJ.
Cassie is an indoor as well as outdoor feline and is constantly crawling around in tall grasses where fleas and ticks hide out, and wait for someone to brush up against them so they can hitch a ride and feed. PJ is an indoor cat but is at just as much risk for a flea infestation as our outdoor cat is. Cassie and PJ are actively playing with each other continuously throughout the day. A flea could quickly find PJ if Cassie was to bring in a flea from outside.
If we didn't use Frontline monthly we definitely would have a flea infestation. At that time we would have to purchase Advantix to get rid of those fleas. When you do a comparison of Advantix vs Frontline you are going to see that Advantix will eliminate the fleas and that Frontline will protect against them from ever latching onto your feline. After the Advantix application to get rid of the fleas we will need to start using Frontline regularly to continue to keep the fleas from coming back.
Fleas hide out in concealed balls of fur throughout the house just waiting for cats to come close so that they can have a meal. The Advantix will not eliminate the fleas that aren't on your feline. After the application of Advantix wears off, your cat will have fleas all over again.
By giving your cat Frontline monthly during the warm weather months you will not have to be concerned about fleas on your feline or about fleas hiding out in the dark recesses of your home, waiting for a host to come along.
