Can anyone tell me what I am doing wrong with application of Frontline Plus? I purchased a 6-pack (for our two cats) at Costco and applied yesterday. I was under the impression that the fleas would die immediately after application. I brought the kitties into the bathroom this morning and did a thorough flea combing on them. To my utter dismay, live fleas were still everywhere on them. I thought that I had applied exactly as the instructions said. Either I've done something wrong, or the product is simply very poor. I believe the Costco brand which is less than half the price of Frontline Plus (maybe even a third less), worked just as well (which really means not too well), and it left the cats very greasy for about a week after and we still had fleas with that product too. I am not recommending either product. I haven't tried this yet, but I have read that (food grade) DE (Diatomaceous Earth) which you may be able to purchase at farm type stores or online, is a natural remedy for the issue of fleas in your home. It apparently dries the eggs up. You can also you it on directly on your pets. It is entirely safe to use (it can even be eaten), except to be careful with application into your carpets as it may create a dust cloud when applying and can irritate the lungs. You just have to apply gently. I am very disgruntled at the fact that I just paid $65 for a product that doesn't even begin to work. It is way too expensive to not have resolved the problem and I really hate using all of these harsh chemicals, but I want fast results. I really think that fleas are becoming resistant to all of these chemical products, because year after year the problem seems to get worse.

Frontline plus for cats absolutely DOES NOT WORK! My cats have never had a flea problem before, but I began using Frontline recently and now we have a HUGE flea problem. I called my local cat groomer and he told me that Frontline is notorious for working only on dogs, not cats. He recommended that I try Revolution or Advantage but not to waste my money on Frontline for cats. Wish I had known that before my house became overrun!!

I will never use this product again, my cat had a sever reaction to it. I will stick to bathing her in Dawn dishwashing liquid.

I have to say that I am not very pleased with this product. I have an indoor cat that has only recently become and indoor/outdoor cat. Being the economical person that I am I started at the bottom pricewise as far as flea control when we noticed a problem. We worked our way up to Frontline Plus which is the most expensive and therefore, one would think, the best. It has not worked. We are continuing to use the frontline in the hopes that it will begin working better since we are out of options. Sadly my poor kitty has a little rash on his neck for a couple of days following treatment. This is in addition to the pesky fleas that have forced us to make him an outdoor only kitty.

Until this product comes down in price, I have a 4 pet home, there is no need to buy this over other products of the same or better caliber.

I think Frontline has changed thier formula. Because the past 2 years I have been battling fleas on and off because the Frontline is not working. I switched to Advantage and it has been working good on the fleas but it doesn't protect against ticks. I need a product that protects against both and I am having a hard to paying alot of money on Frontline when it's not working. I have three big dogs and two cats I have to treat.

This product never protects for long, and doesn't kill the fleas for very long. Now I don't have a strictly outdoor cat, my cat stays inside mostly, but comes out for walks, or when she feels like playing outside, so I feel bad for those who have outdoor cats. The only reason I even tried this product is because my vet put on a treatment during a check up, normally I use a different brand. Long story short... I changed vets after that.
