In answer to Risa's question about finding inexpensive Revolution: Prices for Revolution vary quite a bit. The three sites below are places that I've found it the cheapest in the past. I have NOT ordered from any of these three places, but I HAVE ordered regularly from 1800petmeds.com. If you call them and provide the competitor's website, they will match any online price, and they also have free shipping. The Revoiution that I have gotten from 1800petmeds.com has always been dated far in the future (much more than a year) and has arrived quickly. I'm posting this in hopes that it might save some of us some money on what I believe is very valuable protection for our ferrets. http://www.petcarechoice.com/index.cfm/fuseaction/site.home http://www.petshed.com/revolution.asp <http://www.valleyvet.com/ct_detail.html?pgguid=2E87C515-7B6A-11D5-A192-00B0D0204AE5%26ccd=ILS005> Jeff In Memory of Neo Caring for Trinny, Morphy, Baby Girl, Luna, and Dozer [Posted in FML 6144]
