Actually it is roundworms that they can get from their mother, but yes they can get tapeworms as well.
I have heard of that too.

I'd suggest a trip to the vets if you haven't done so already (should get tested for leuk & fiv if she's old enough too).

It may just be from too much grooming or roughhousing like mentioned before too.
