Buying Guide

While the aforementioned brands of cat dewormers come highly recommended, you’ll have to choose between them in order to find the best solution for your cat. Luckily, there are a few standard factors that one should consider in order to achieve the best deworming results.

Identify Your Cat’s Needs

Before committing to a specific type of dewormer, you’ll likely first want to identify what sorts of worms your cat is facing. If your cat is experiencing tapeworms, a hookworm solution will likely be of little help.

There are a few main types of worms your cat could be experiencing: roundworms, tapeworms, lungworms, and hookworms. While there are solutions out there built for all-purpose worm relief, such as Bayer’s dewormer, they are often more expensive.

These tablets can be a godsend after every other path has failed, or for cats truly experiencing multiple types of worms. However, they may not always be completely necessary.

By first identifying the types of worms your cat is confronted with, you can take a more direct approach to curing them quickly.


These worms are more easily identified within your cat’s coat than others. Often, these worms may appear as small grains of rice stuck in your cat’s fur. Upon closer inspection, these worms appear long and flat, similar to pieces of tape.

Because these worms often become stuck in a cat’s fur, they are often carried from one animal to another by fleas. It is likely that if your cat is suffering from tapeworms they are also suffering from fleas and may require further treatment. By the way, to prevent fleas in the first place, check out our list on flea collars.


These worms can prove to be extremely harmful to cats. Cats may become infected with these worms by either ingesting them, through another animal already infected, or by having these hookworms bury themselves into the cat’s fur.

Making themselves at home within a cat’s intestinal wall, these parasites keep themselves alive by feeding off of your cat’s blood. In turn, this can cause your cat to become anemic.

Anemia in already susceptible cats such as kittens or nursing cats can lead to serious health complications for the already compromised immune systems of these cats.

If you suspect your cat may be suffering from hookworms and present themselves as more lethargic than normal, it is best to get a professional opinion as soon as possible in order to avoid further health complications for your cat.


These worms are particularly insidious, beginning by attaching themselves to your cat’s intestines, these worms quickly multiply and lay eggs that can attach themselves to other organs.

One roundworm soon leads to many, and this infection is best fought off while there are fewer worms to treat. Prolonged exposure to roundworms without adequate treatment can potentially lead to a prolonged period of treatment.

Roundworms are transmitted through other small animals which are infected with them, as well as bodily excrement from infected creatures, including a mother’s milk.

In fact, these worms are so contagious that not only do owners have to worry about their other pets catching these worms, but humans do as well. Those with cats suffering roundworms will likely want to try both internal and external treatments in order to keep their homes as safe as possible.

Cats infected with roundworms will likely experience excessive vomiting and diarrhea, and the worms will be found present in their excrement.

cat pill dewormer Lungworms

These are worms that infect a cat’s lungs directly. Rooting themselves in a cat’s lungs, these worms can cause breathing problems for otherwise healthy cats.

Lungworms are carried by contaminated animals which may be ingested by housecats, as well as carried within infected water.

If your cat is exhibiting signs of extreme difficulty breathing or wheezing, it is best to bring it in to the vet as quickly as possible. Your vet may identify excessive fluid buildup within your cat’s lungs and diagnose your cat as carrying lungworms.

Choosing Between Types of Solutions

After diagnosing the type of worms your cat is suffering from, you’ll next want to figure out what kind of solution you’ll want to give your cat. There are various types of solutions between the pill and liquid forms of worm medicine for cats.

Some variations utilize more naturally occurring ingredients than others, making them safer for kittens and nursing cats. Completely natural solutions will likely not be as aggressive towards worms as their chemical counterparts and may not get rid of worms effectively.

You’ll want to choose a solution somewhere in the middle, allowing the solution to be gentle enough for your cat to use it without harm while still being damaging enough to the infectious worms.

Tapeworm Treatments


This is an ingredient commonly found in many tapeworm medications for cats for the simple reason that it impairs the tapeworms. By keeping the tapeworms from being able to digest nutrients, the tapeworms quickly die out.

Eventually, the tapeworms will starve to death and disintegrate, riding your cat of the pests.

Roundworm Treatments


This solution is found in roundworm medication as it works to paralyze roundworms. Without the ability to reproduce and consume nutrients, no further tapeworms will be created and the existing tapeworms will die out.

Medicines with this ingredient should be dosed out appropriately as overdoses can have negative side effects for a cat’s health and digestive system. You will know if you’ve given your cat too large of a dose by an increase in your cat’s nausea.

Hookworm Treatments

Pyrantel Pamoate

This ingredient is found in both hookworm and roundworm treatments and works to paralyze both worms. Hookworm rely on attaching themselves to your cat’s intestinal walls in order to survive.

This medicine’s paralytic effects cause the hookworms to fall off of the intestinal wall and pass through your cat’s stool.

Check Side Effects and Doses

Some of these medications may potentially do extensive harm to your cat. It is best to follow the directions on the label to a tee in order to avoid this. It should tell you if it is safe for kittens, and if so, from what age it is safe for them.

Do not give medication that is not advertised as safe for kittens to young cats or cats that are pregnant or nursing, as the medication will likely be transmitted to the kittens that way.

It is also important to follow the recommended instructions for dosage. To ensure your already vulnerable cat is not exposed to further potentially harmful circumstances. Dangerous doses of these medications can exacerbate your cat’s worm symptoms, causing vomiting and diarrhea.

If you are following the medication’s given instructions and find your cat is getting worse, immediately stop dispensing the medication and take your cat to a professional.

Keeping Your Cat Worm-Free

The best way to ensure your cat does not suffer reinfection is to keep your cat indoors and away from wild carriers of worms. Keep your home clean and ensure proper steps are taken to keep fleas away, as they can also carry these worms.

Keeping your cat strong and healthy can help its immune system to fight off further infections.
