My cats have fleas and diareha both. I picked up some tape worm medicine in hopes that this would cure the problem. Can you give me some other alternatives to this problem. I have several cats.:confused: :confused: :confused:

When was the last time they were at the vet's office?
Tapeworms are caused by ingesting a flea, but have they been dewormed for rounds, hooks, or whipworms?
What food do they eat, how old, are they altered?
