Best Cat Wormer Medicine
Last updated on February 24th, 2023 at 09:08 pm
All cats are likely to have worms at some point or another as intestinal parasites are very common, in fact, Cornell University states that as many as 45% of cats have gastrointestinal parasites.
Fortunately, worms can be prevented and treated with relative ease. You can actually treat worms using over-the-counter wormer medicine but it is important to know there are different types of worms which mean there are also different types of dewormer available.
Using this guide, you should be able to treat your cat quickly, easily and effectively at home.
Best over-the-counter cat wormer
Choosing the best dewormer for your cat starts with knowing which type of intestinal parasite your cat has.
In cats, there are three common types of worms:
- Roundworms – these are the most common type of worm and are usually spread by your cat ingesting the eggs. Kittens can be infected with roundworms by suckling on a mother who has roundworms. Signs of roundworms include loss of appetite, weakness and a bloated stomach.
- Tapeworms – these are common, particularly in cats who have had fleas as tapeworms can be spread by ingesting an infected flea. If your cat has a tapeworm it will lose weight as well as its appetite, you may also see worm segments in your cat’s feces. Tapeworms are flat, long worms that look like a piece of tape, as they are segmented they may also appear similar to grains of rice.
- Hookworms – these worms are generally spread by ingesting eggs or walking on contaminated soil, this means hookworms can be spread from one cat to another via a shared litterbox. Your cat may get lesions on their feet, loss of appetite and diarrhea or constipation and may develop a cough. Hookworms feed off cats’ blood so can cause anemia and can be fatal if left untreated.
Deworming medicine is usually available as tablets, spot-on or drops. There are broad-spectrum wormers available but these often come with more side effects than a specific dewormer, it is best to take your cat to the vet to identify which type of worm they have so you can more accurately treat the issue.
As dewormers are available as prescriptions and over the counter, you will find a selection of wormers in pet stores and even in supermarkets.

This liquid dewormer is designed to treat roundworms. It contains piperazine which will paralyze roundworms, allowing your cat to get rid of them via their feces.

How Do You Kill Worms in Cats?
Worm treatments are usually enough to kill worms in cats. After worming, the dead worms will be passed out of your cat via their feces so after a worming treatment you will likely see a higher number of worms being passed by your cat than you have seen previously. This is just a sign that the treatment has been effective.
You can keep on top of the issue by treating for worms regularly. You can also actively prevent worms by insuring food bowls, water bowls and litter trays are cleaned and disinfected regularly.
You may want to consider keeping your cat indoors as this will greatly reduce the chances of them contracting worms as infected cats, rodents, birds and fleas can carry and pass on worms.
Keeping your home flea free will also help to reduce the likelihood of your cat contracting tapeworms.
How Often Should You Worm a Cat?
Treatment for worms should be a regular occurrence. Here is a general guide based on your cat’s age and the type of worming treatment being used:
| Age | Frequency of Roundworm Treatment |
| 2-8 WEEKS | Every 2 weeks |
| 2-6 MONTHS | Monthly |
| 6 MONTHS + | Every 1 – 3 months |
|
| |
| Adult Cats | Every 1 – 3 months with a product that is designed to work against both roundworms and tapeworms |
| If your cat hunts a lot your vet will likely advise monthly deworming as they are at a higher risk of being infected with worms. If your cat is pregnant or nursing seek veterinary advice before worming. |
| Age | Frequency of Tapeworm Treatment |
| 6 WEEKS – 6 MONTHS | Monthly |
| 6 MONTHS + | Every 3 months |
