My cats had flea's when I first brought them home, I treated with Frontline and blitzed the home with this http://www.medicanimal.com/product/~product_id=514?gclid=CJTlidjM26sCFcYPfAodjE5UPQ this spray is brilliant stuff I will swear by it, I haven't had a flea on my cats since or had any at all in the home. This spray was killing them instantly in my cats beds, so I'd see if you can purchase some online from somewhere :) Hope this helps.
