Hi Folks, If you have used the Advocate Flea Treatment on any of your pets, please could you let me know how you got on with it. My cats appear to have become immune to the Frontline products and I have been really struggling with this problem for about 18 months now. I saw an old thread which mentioned this product & brought it to my attention however there are not many reviews on t'internet and those that I can find are mixed so I would really love to hear the opinions / experiences of the nice people on PF to help me decide if it is worth purchasing & trying. I've put this thread on General Chat as I wanted the opinion of all users not just those on the Cat section. Many thanks in anticipation of your comments. PS: I would have attached a poll but couldn't figure out how to do it!! I'm such a fickie!!
