[ATTACH=full]186[/ATTACH] Little Ann was still getting fleas after I gave her advantix. So I sprayed her with this stuff last night. She went nuts at first, ( she was so mad she wouldn't even let me look at her), but you can always tell when the spray is working because they they do go nuts. Well, as of today there are no fleas on her at all!! I don't know how often I'll have to use it, but if it works? I'll use it however often I need to!
