Bests & Worsts Reviews from Amazon

First let me state that this is NOT a cure-all or a preventative treatment!! It simply kills ADULT fleas that are ON the cat for a few hours/up to a day. My cat was suddenly infested and I was desperate!! II just gave the pill to my cat, and 20 mins later she was howling and jumping all over the place, and I see that there are already fleas on top of her fur and just falling off! I found her in the bathtub less than an hour later, frantically grooming herself, surrounded by dead fleas (see photos!!). I couldn't believe it. People who say it doesn't work are crazy! Lol. It works, but if you have fleas OFF your pet (outside, or carpet, or other untreated pets)....they will jump back on the next day!! So this must be used as part of a regimen. I took one star off because it's so dang expensive, over $4/pill! P.S. She calmed down after about an hour and a half. :)
