Every once in a while a couple of my furkids will begin to pass worms, but they are not tape worms. I beleive they are called "round worms", not because they are round but so named by the way of their locomotion. My furkids usually get them after eating gophers. So, when I see any of them feasting on these rodents, then I will watch for the round worms. Often they appear at sunset and sunrise, for some strange reason. There is available at most any pet shops a de-wormer specifically made for common round worms for cats and dogs.
