Hello I received an e-mail asking me to respond a while ago but I held back because I had doubts about the product. To break the feedback down into 2 parts - product and service. The serviceyou offered was great, I spoke to someone on the phone as I was concerned that the product wasn't working and she was really helpful, offered lots of advice but suggested that the product probably wouldn't have worked for the problem (cat lice) so this was a bit disappointing ads I had spent £36 for nothing. Anyway excellent service would definately shop here again Product, frontline. Didn't work. I ordered enough to treat my 3 cats 3 times, which would equate to monthly as suggested (I don't do this so regularly with any of my animals as I think this is over-medicating them). However, while the product said it treated lice biting insects and they would be dead within 24 hours, there were still living ones on one of my cats after 24 hours from treatment. I then made the decision to treat the cat again with another frontline a day or two later and there were still one or two living lice after 24 hours. I was annoyed as the product was advertised for killing lice. It has been suggested that advocate would have been better but the product is on prescription and it doesn't actually say that it will kill lice. I considered asking for my money back on this product either with yourselves or frontline directly.
