Anyone got any help and advice for the flea infestation my cats have gifted me? I've never had a real flea problem before - couple of doses of frontline and a few sprays of the house and job done (kind of every 2 years), but this time it is going ON and ON and ON and I am covered in bites (never had that before either!) and itching like crazy! We are about 6/7 weeks in of treating with frontline and now advantage, bombs and spray. Arrgh!
