I have tried Dawn, some shampoo from the vet, and some flea and tick stuff for the back of her neck. None of which has helped. I feel so badly for her, because all she can do is scratch. I have read your flea section, and I've tried a lot of things, but all I can see is a lot of stuff that has helped for some, and hasn't for others. I just wish there was something that helped everyone, lol.
My husband is going to fog our home and then during that time I am going to clean my kitty and Lexi with the Dawn detergent. Hopefully that will work.
