The kitten I bought for my daughter for Christmas ended up with fleas and I bought this at the store to try and fix the problem. It was cheap and the flea problem was not that bad, so I thought this would work. I did not want to use the Frontline I use for my other cat on a kitten. This flea treatment is the most horrible treatment on the market right now. It definitely is the definition of cheap. This treatment did not help my kitten get rid of his fleas at all. In fact, they got worse and my other cat got them. I was so angry. Also, he got a little rash where I squeezed this product on his neck. I wished I could have returned it, but that was not even worth the money I paid. I ended up calling the vet and she told me I could give him the Frontline. This is definitely a lesson learned. Do NOT give your cat or kitten Sergeant's Gold Squeeze-On for Cats and Kittens. I regretted the decision and so will you.
