A brand called Bio Spot can kill cats too. There was an adopter from my prior organization that used that on a cat and it was the cause of death because of some ingrediant that was in the flea control.
I advise to stay away from normal store brands that are in stores like Wal-Mart, Target, Big K, etc and stick with Revolution, Advantage, and Frontline.
Also, dog and cat Advantage is the same stuff! They just sell it differently, but you can use it on either, just pay attention to the dosage with the weight of your cat. They tell vets this, but vets don't tell the public, they do tell rescues.
