I was really disappointed in the effectiveness of this product. I bought it for a litter of kittens that were five months old. I put it on all of the kittens and the next day they had fleas. I could not recommend this product.

The product seems to do its job. I have 3 cats and have had no problems with fleas or ticks. I only ask that the applicator would be shaped more "cat friendly" because the sharp edges might scratch the cat's skin.

easy to open, easy to apply. cats tolerate it well, but cats are itching before the 4 week reapplication. I'm going to apply at three weeks. I will repurchase tho.

I decided to try this drop since it was cheaper than what I had bought previously. My cats now have fleas. We have never had a problem with fleas until I switched to this product.

This product does not work!! I tried it for two months and washed my cat in dawn dish soap and he had over 200 fleas on him. Would highly not recommend!

Used for several months on our cats, and have a huge flea outbreak on our hands. Please do not rely on this flea treatment. We are switching to Credelio and now spending money on Capstar medicine to try to keep the population at bay.

I purchased this for my 16 week old kittens and it did not work at all. 3 days later the kittens still had fleas. Do not waste your money on this product

We have used this for a couple of years and it has worked well; however, the last batch bought does not kill fleas. We have four cats, three barn cats and one in and out. Watching them scratching so much and seeing fleas is awful. Will go back to advantage next month.

Excelente

Could work better
