I just put up an auction for a sealed 4pk of K9 Advantix (10 lbs and under of course) if anyone is interested. Reason I am selling it is because it isn't safe to use around cats and we just adopted a kitten last month. Package was originally purchased from 1800petmeds.com on Aug 9. I know a few people here use Advantix so I figured I would post it here.
