Cats become infested with worms by eating fleas or eating small animals that contain fleas or worms, such as mosquitoes. A stool sample should be taken to a vet to find out which type of worms your cat has, with the most common being tapeworms, roundworms and hookworms. According to CreatureLover.com, you should never give a cat an over-the-counter (OTC) medication for worms without consulting with your vet first. Many of these OTC treatments are toxic and have caused cat fatalities.
Tape Worm Tabs
Tape Worm Tabs is an OTC medicine that is FDA approved. It removes tapeworms from cats over six weeks of age. It can be crumbled into food or orally administered. According to FleaSmart.com, because Tape Worm Tabs is the only OTC treatment that contains Praziquantel, which is the most recommended ingredient for removing worms from cats, this product is the best OTC treatment available.
