WHAT ARE ROUNDWORMS?
Like hookworms, roundworms are parasites that live in the intestines of their hosts. Also, like hookworms, roundworms harm your pet by depriving it of nutrients. One key difference between roundworms and hookworms is that roundworms are much larger, which can lead to additional complications. A heavy infestation of roundworms can even cause intestinal blockage. Roundworms can lay 100,000 eggs in one day. Roundworms typically do not cause symptoms, but their presence may be evident in the host's stool. In young puppies or kittens, mild vomiting or diarrhea may result. Roundworms are the most common internal parasites in cats.
