Amazing!
I don't usually leave reviews but I feel like I should for this. My dog was suffering really bad with fleas where nothing we tried worked. This included numerous sprays and cream to repell fleas even garlic tablets but they just wouldn't budge. I came across this on Amazon and read reviews from other people and majority said it worked well so I went for it. No word of a lie within a day the fleas disappeared and going on 10 days now still not a flea in sight which is a relief for me and my dog. No more bites on my legs and my dog is no longer scratching and red raw. Would definitely recommend this product absolute life saver

Value price
Not sure about the flea control as I cannot see fleas on the cats before or after application. A good price and easy to apply. If I was a cat I would bathe in it twice a year.
