Tri-Force works well. Have used it on 9 cats - no fleas or ticks! (One cat, however, did lose hair in the spot where administered so use another product for him.)

We had been using Frontline for our one indoor dog, one indoor cat, and one outdoor cat. We had used it for years. All of the sudden, it stopped working and we didn't realize it until we were inundated with fleas throughout the house and the pets. We immediately treated the house and switched to Triforce for all three pets, and WOW! Immediately we saw results. It simply took care of the entire problem. IT'S CHEAPER, TOO!

Triforce - very good price, now I know why, way too much medicine in the tube, cats tried to lick off, rubbed medicine on carpet, finally had to wipe off with baby wipe because the manufacter warned against animals ingesting. Have used Advantage for cats and will go back, just a small amount, cats barely notice and no worries. Would rather pay for more and know that they are protected from fleas.
