“This stuff WORKS! The only trouble is if they throw it up, it's a big money waster. But if they keep it down it's a month of great protection. My cats have a terrible reaction to the back of the neck applications so this is a lifesaver for us!! The idea of the product deserves 5 stars...but since it STINKS like bug spray, the cats HATE the smell and the taste and it's a struggle to get them to keep it down...I'm giving 3. Improve the smell and taste to be trickier and it should get a nobel prize!”
“Best place on the web to get flea meds. Best prices. Fastest shipping. And Comfortis is the ONLY med that worked for my cats' fleas. N. central FL had a really bad problem with fleas this year- people who never had them got them, and they were hard to get rid of, even with dosing every 2 wks with a variety of topicals. One dose of Comfortis for every one and the fleas were 100% gone. It is now their one and only flea med!”
