She's on frontline. we bathe her in flea shampoo a few days before her application. we rub lavender shampoo on her neck. We've given her dawn soap washes, vinegar baths. we have a carpet spray that we use in the bedroom before we vaccuum (we also use it on the couch. I put borax powder in the vacuum canister before vacuuming. It's awful.
When she sit on my lap for long enough I brush her with the flea comb and toss any I catch into a cup of water and dawn.
