Catlover, foodgrade diatomaceous earth will rid your cats of tapeworms. 1/2 tsp for kittens and 1 tsp for cats in wet food. Not sure how many days you would have to feed though. I just do for a few extra days when I no longer see the worms. Of course, you would first of all need to treat your cats for fleas, or they will just groom themselves and get tapeworms again.
