  • The best dewormer for cats will be determined by the type of intestinal parasite your cat has, but it should be made with powerful active ingredients in an easy-to-administer formulation.
  • Recommended by veterinarians for being both safe and reliable, Bayer Drontal Broad Spectrum Dewormer is the best cat dewormer on the market - if you can afford it.

You may not be able to tell just by looking at your cat whether he has worms, but Cornell University veterinarians claim that as many as 45% of cats have intestinal parasites at any given time.

In most cases, parasite infestations cause nothing more than mild to moderate digestive symptoms, but a heavy infestation can lead to weight loss, difficulty breathing, and even malnutrition - especially in kittens.

Fortunately, treating your cat for worms is easy and shouldn't require much more than an over-the-counter dewormer. Dewormers for cats come in a variety of different formulas for cats of different ages and to treat different types of parasites.

Why you'll love them: HomeoPet Feline Wrm Clear Drops are safe for kittens because of the homeopathic formula that targets many kinds of worms.

Intestinal parasites in kittens are very common. They can get worms by nursing from an infected mother cat and could even be born with worms. Because kittens are more likely to be sensitive to chemical ingredients, you may want to consider a more natural option. Our top pick for the best dewormer for kittens is HomeoPet Feline Wrm Clear Drops.

HomeoPet's Drops use a homeopathic liquid formula to treat and prevent infestations of hookworms, roundworms, tapeworms, and whipworms. This dewormer works by boosting your kitten’s immune system and digestive system to naturally expel the worms from his body.

Why you'll love them: Bayer's Tapeworm Dewormer Tablets for Cats are proven to kill tapeworms in a single, easy-to-administer dose.

If you notice small white pellets in your cat’s feces or you notice him licking or biting the area under his tail, he could have a tapeworm infestation.

Tapeworms are often passed to cats when they ingest adult fleas that have been infected, though they can also be transmitted through wild animals. As the tapeworm grows, segments break off and pass through the intestines in your cat’s stool. The best treatment available to remove tapeworms is Bayer Tapeworm Dewormer Tablets for Cats.

Bayer's Tablets are the top choice for both cat owners and veterinarians to tackle tapeworm infestations quickly and safely. These tablets come in a three-pack with each tablet containing 23mg of the powerful active ingredient praziquantel. This ingredient is effective against the most common species of tapeworm, Dipylidium caninum and Taenia pisiformis, eliminating them in a single dose.

Entirely Pets comments on how well the active ingredient praziquantel works to paralyze and eliminate tapeworms. Kitty Catter also notes that it is a very safe and effective formula that can be fed whole or crushed and mixed with food.

In addition to having more than 1,200 reviews on Amazon, the Bayer Tapeworm Dewormer Tablets for Cats also carry an Amazon’s Choice award and a 4.5-star rating.

The most common intestinal parasites seen in cats are roundworms, accounting for between 25% and 75% of the infestations that occur in the United States each year. In many cases, cats become infected by eating rodents, feces, or other substances containing roundworm eggs.

Roundworms feed on the food your cat eats, which, over time, can contribute to malnutrition so it is important to treat roundworm infections right away. For this purpose, we recommend ProSense Liquid Dewormer for Roundworms.
