I just found a tapeworm segment on the cat's tail, even though he is regularly wormed and de-fleaed (although fleas haven't been a problem). After a spot of internet research, I've just ordered some Droncit spot on stuff. But, can cat tapeworms transfer to humans? And if so what are the symptoms? DD has had a tummy ache for a week or so and I'm wondering whether I need to get her wormed as well. I have no idea obviously how long the cat's been carrying worms around.
