DO your research! This IS safe to use. It's used in human food supplies as well as cattle feed. You can find tons of info on it online and in books. I am NOT the only one who has used this to deworm their pets.

She could easily take the cat to a deworming clinic to get them dewormed by a vet who knows what they are doing, and Petsmart sells Tapeworm Tabs over the counter that work very well, Praziquantal...or however it is spelled. It's the equivalent of Drontal or Droncit and will kill not only tapes, but roundworms and hookworms. Just because you used this remedy (which sounds very sketchy to me) doesn't mean it is safe to use!

And not to jump on the bandwagon here but I wholeheartedly agree with Shais_mom and Kay!
