Intestinal Parasites Intestinal parasites are a common problem with puppies and kittens but most can be easily treated once they are diagnosed. Roundworms, tapeworms, hookworms, and whipworms are the most common intestinal parasites in puppies and kittens. Other intestinal parasites include microorganisms such as coccidia and Giardia. We recommend having at least two stool samples checked during your puppy / kitten’s first year followed by annual fecal exams as an adult. Your dog or your cat will be constantly exposed to parasites, many of which are transmissible to people.
All kittens and puppies should be routinely dewormed. A negative fecal sample does not necessarily indicate absence of parasites; eggs are shed intermittently.
