You all are so interested...all kittens are born with round worms. those are the ones that you have to watch out for in the litter box cuz all cats walking through the same litter box or washing the kittens bum will get them- they are so common. And they are not round. They are spagetti. And to see a live one is truely disgusting. And to see a cat INFESTED is the worst! they can be either pooped out in a big blob of moving spagetti (friend of mine witnessed at shelter) or puked up- which is a bad sign. I have seen single live round worms and many dead. The dead look like dried spagetti in the litter box.
