This is the best flea treatment that I have ever used on my cats!! I do use others such as Effipro/Frontline when I haven't got around to getting a prescription but always come back to this as it works so much better due to it sterilizing the flea eggs so completely breaks the flea life cycle. It also kills earmites, lice and worms (apart from tapeworm) which is great if you find it very difficult giving tablets to cats(another spot on product Droncit is for tapeworm).
easier to apply that frontline as there is less volume and it doesn't smell quite so chemically. in theory covers ear mites also which is the reason i use it. good value but prescription required
