This product is the only topical flea,tick Plus product that I have tried that does not cause a rash, other than the Revolution Plus ( which is the exact same product only labeled for the US). It doesn't have a oily residue that irritates cat's skin and it absorbs quickly! That means less stress trying to get it on the cat because they hardly feel it go on. It protects better than any product I have ever tried. I have outdoor cats and as long as I am consistent about treatment, they never have fleas, ticks or ear mites!
