any suggestions on which med to use to treat 3 cats with tapeworms? Where can I buy the med, on-line or locally?

I already use Revolution for fleas/ticks/mites/etc but now have seen evidence of tapeworms in 3 of my cats.

Thanks much. >^.,.^<

Found all kinds of sites when I googled "tapeworm meds for cats" , here's one of them.

PetCareRx - Discount pet meds, pet medications and pet medicines available at our pet pharmacy (http://www.petcarerx.com/pcrx/Default.aspx?upi=0&id=1447&gclid=CLHY_6XLs5wCFdZM5Qod2Sf-oA)

This has good reviews. I'm getting to where I don't want to use any chemical on my pets.
