Our Top 3 Best Cat Dewormer Picks

In most cases, the best dewormers work best when you know exactly what kind of parasite you’re dealing with. However, there are dewormers that can tackle a wide range of infestations quickly and effectively. Here are our top picks for all kinds of worms:

1. Elanco Tapeworm Dewormer (praziquantel tablets) for Cats (Best Overall Pick)

Simple and effective, the Elanco Tapeworm dewormer is a top-selling product and an excellent way to quickly remove tapeworms from cats. The product comes in a pack of three tablets, which you can crumble or mash to mix with your cat’s food if they have a hard time taking pills directly. 

The Elanco Tapeworm dewormer works on all common kinds of tapeworm, including Taenia Taeniaeformis, and Dipylidium Caninum. However, this medication is only recommended for cats and kittens over six weeks of age. Make sure you check the instructions before giving these pills to your furry friend. There’s plenty of guidance on exactly how much of a pill your cat needs depending on their weight.

Types of Worms: Common Worm Issues for Cats

As mentioned above, worming formulas are often most effective when you know exactly what you’re dealing with. Not all worming solutions will be suitable for every infestation, so it’s best to take your cat to the vet initially when you recognize symptoms of a potential parasite in your cat. 

One point to keep in mind is that all forms of worm infestation can be extremely problematic for cats, and the problem only gets worse over time if you don’t apply treatment rapidly. Getting the right solution quickly can make treatment a lot simpler and faster. 

Some of the most common forms of worms cats encounter include:

  • Roundworms: The most common form of parasitic worm in any cat, roundworms cause a range of significant problems including gastrointestinal upset, diarrhea and issues within a cat's stool. These worms live in soil and can easily make their way into your cat’s digestion system, particularly if your cat spends time outside. These worms can often be seen in your cats’ feces as they become mature. As soon as you know you’re dealing with roundworms, you can find a range of different treatment options online, including gels and liquids, which are great if your cat hates tablets. Be careful when handling the litter tray, as roundworms can pass from cat feces into humans too.
  • Tapeworms: Not often a problem in kittens, but a frequent issue in adult cats, tapeworms are contracted from the stomach of fleas, after your cat eats a flea. These worms are therefore commonly accompanied by a flea infestation, which you may need to address separately. There are a number of products designed to treat tapeworms which can also kill flea larvae. During their initial stages, tapeworms usually look like small grains of rice. If you swallow one accidentally, you may end up contracting a tapeworm yourself.
  • Hookworms: Hookworms are more common in dogs than cats – but if you live in a household with multiple pets, you could find the infestation travels between animals. The most common way for a cat to get hookworm is by interacting with an infected dog. The hookworm lives in the small intestine of your cat, and actually consumes blood, which means your cat is at risk of suffering from various issues, including anemia.
  • Lungworms: As the name might indicate, the lungworm attacks the lungs of the cat, and are carried on slugs and snails, meaning your cat is more likely to get them when in wet locations, and during wet seasons. Interestingly, your cat doesn’t necessarily need to eat any slugs or snails directly to be infected by a lungworm. If another animal eats a slug and your cat eats that animal, it’s possible for the infestation to pass from one species to another.
  • Heartworms: Although heartworm was originally only an issue in dogs, it has also become an increasingly prevalent issue in many felines too. This problem is passed into cats through bites from mosquitos. At this time, there is no proven treatment available for heartworm, but your cat’s immune system should help to fight off the infestation over time. It’s still best to speak to your vet if you have any concerns, of course.

What about Other Infestations?

Notably, many of the products you can get for treating common worm infestations in your cat can also be used for the treatment of various other bugs and infestations. It’s common to see a single treatment capable of taking on various kinds of ear mites, worms, ticks, and fleas in and around a cat's body. If you’re concerned your cat might be exposed to other infestations at the same time as a worm, the best thing you can do is look into a comprehensive form of treatment capable of tackling everything at once.

Worming Kittens: What You Need to Know

If you’ve recently adopted a kitten, or your cat has kittens, then you’ll need to worm them as soon as possible. The majority of kittens will be carrying worms transmitted from their mother’s milk, so it’s important to tackle the issue as quickly as possible.

Symptoms of Worms in Kittens

Ideally, worming your kitten immediately, as soon as they are old enough to receive treatment, should help you to avoid having to deal with any symptoms. However, there’s a chance you may be a little too late with your treatment, in which case you might begin to notice symptoms. 

Symptoms of worms can vary from one cat to the next, and they often differ depending on the kind of infestation in question. In many circumstances, you might notice your cat begins to suffer from weight loss, even though they might look a little bloated around the midsection. If your cat seems to be losing weight unexpectedly, you should always take them to the vet as quickly as possible. 

The sudden loss of weight in a cat can indicate a range of serious health problems, beyond a basic worm infestation. It’s also worth looking out for symptoms like:

  • Changes in your cat’s behavior: It’s common for your cat to change its behavior when its not feel like itself. If your cat seems to be withdrawn or acting strangely, you may want to consider taking them to the veterinarian. It’s also worth looking for signs your cat is uncomfortable around the bottom area. If your cat is dragging its butt along the floor, this is a common sign of worms and infestations.
  • Signs of worms: Many species of worms can show up in your cat’s litter tray. You might notice flecks of white rice-like substance in your cats’ feces, or even entire pieces of a worm in bowel movements. Be careful to wash your hands thoroughly after dealing with infected bodily movements from your cat, as some can pass to humans.
  • Diarrhea:Another common symptom of fleas and worms alike, diarrhea is a sign something isn’t right with your cat’s intestinal system. Keep an eye out for any unusual bathroom habits, as this can also indicate a range of other health conditions.

Another common symptom might be a change in your cat’s appearance. Some cats suffering from parasites have rougher, patchy fur.

How to Apply Cat Dewormers

If you need to provide your cat with a treatment for worms or fleas, there are usually multiple options available. Tablets are the most common option, specifically for more complex kinds of worms. However, you might be able to access liquids and gels too. Some of the most typical options for application include:

  • Topical: Topical treatments are medications you can apply directly to your cat’s skin. In the case of flea treatments and dewormers, you can usually find “spot-on” applications which you apply to the back of the cat’s neck, between the shoulder blades. The skin soaks in the substance, which moves through your cat’s bloodstream to get rid of infection. This is a good option if you struggle to give your cats tablets and pills.
  • Tablets: The tablet is the most common form of treatment for deworming. Usually, you’ll be able to feed a tablet to your cat whole, or you can crush the pill and mix it with your cat’s food. Many tablets intended for kittens will be easy enough to break in half.
  • Chewable: Chewable capsules can be chewed before swallowing. Many cats won’t like this option, because tablets don’t typically taste like something your kitty will want to eat. You’ll need to make sure the substance has an appealing flavor or scent.
  • Liquid: One of the most versatile medication options, liquids can be mixed with wet foods, treats, and water to deliver to your cat with very little stress. You can even give liquid directly according to the instructions on the packaging.

If you are struggling to get your cat to take their medicine don't panic, that is perfectly normal. You may want to check out these two articles below which are crammed full of helpful tips when it comes to medicating your cat:
