Treatment
Several dewormers are effective against roundworms. The examining veterinarian usually gives kittens pyrantel pamoate or some other medication safe for use in young animals. Use caution if purchasing over-the-counter dewormers since many do not eliminate all of the types of ascarids that commonly infect cats. Cats and kittens can be sensitive to medications and only should be given ones known to be safe. The examining veterinarian will know which products are safe and most effective.
