Worms in Cats: Symptoms, Treatment, and Prevention Every Pet Parent Should Know

Worm infestations in cats are more common than many pet owners realize. These internal parasites can affect cats of all ages, from playful kittens to adult indoor cats. While some cats may show no symptoms, worm infections can lead to severe health issues if left untreated. In this guide, we’ll explain the types of worms in cats, how to identify symptoms, treatment options, and effective ways to prevent them.

Types of Worms That Affect Cats

Several types of intestinal and parasitic worms can infect cats. The most common ones include:

  • Roundworms – The most widespread in kittens and adult cats. These worms look like long strands of spaghetti and can reach a length of several inches.
  • Tapeworms – Flat, segmented worms that often appear in the cat’s feces or around the anus, resembling grains of rice.
  • Hookworms – These are smaller but more dangerous. They latch onto the walls of the intestines and consume blood, which can lead to anemia in severe cases.
  • Whipworms – Though less common, they can still affect some cats and cause digestive issues.
  • Heartworms—Unlike intestinal worms, heartworms live in the heart and lungs and are transmitted through mosquito bites. They’re more common in dogs but can affect cats as well.

How Cats Get Worms

Cats can become infected with worms in several ways:

  • Ingesting infected fleas or rodentsTapeworms often come from swallowing fleas during grooming.
  • Eating contaminated food or water – Outdoor cats are especially vulnerable.
  • Mother-to-kitten transmissionRoundworms can be passed from an infected mother to her kittens during nursing.
  • Through the skinHookworm larvae can penetrate the skin if your cat walks on contaminated soil.

Even indoor cats are not entirely safe, as humans can unintentionally bring parasite eggs into the home on their shoes or clothing.

Common Symptoms of Worms in Cats

Some cats may not show obvious signs of a worm infestation, but here are some symptoms to look out for:

If you notice any of these signs, you should consult your veterinarian immediately for a diagnosis.

Diagnosing Worms in Cats

Your vet requests a stool sample under a microscope to check for worm eggs. Sometimes, blood tests may be required to detect heartworms or severe infections. Proper diagnosis helps determine the best deworming treatment and rule out other possible health issues.

Treatment Options

The good news is that most worm infections in cats are easily treatable. Deworming medications come in various forms:

  • Oral tablets or liquids – These are commonly used and can be prescribed by your vet.
  • Topical treatments – Easy to apply to the skin, often used for flea and worm control together.
  • Injections – Sometimes used for severe or specific types of worms.

Never use over-the-counter or dog-specific worm treatments without consulting a vet. Cats have different tolerances, and the wrong medication can be harmful.

Preventing Worms in Cats

Prevention is the key to keeping your cat healthy and worm-free. Here are some effective preventive measures:

  • Use a monthly parasite preventive – Many products protect against fleas, ticks, and worms.
  • Keep litter boxes clean – Scoop daily and wash the box regularly.
  • Avoid feeding raw meat – This can contain parasite eggs or larvae.
  • Practice flea control – Use flea prevention year-round, as fleas are a common source of tapeworms.
  • Regular vet checkups – Annual or biannual vet visits can help catch early signs of infestation.

If your cat goes outdoors or lives in a multi-pet household, more frequent worm testing and deworming may be recommended.

Can Humans Get Worms from Cats?

Yes, some cat worms are zoonotic, meaning they can infect humans. Roundworms and hookworms are the most common. Young children and those with weakened immune systems face a greater risk. Maintaining proper hygiene—like washing hands after cleaning the litter box or touching cats—can significantly reduce transmission chances.

Final Thoughts

Worms in cats may be common, but they don’t have to become a serious health issue. With the right knowledge, proper treatment, and regular prevention, you can ensure your feline friend stays healthy, happy, and worm-free.

If you think that your cat has worms, don’t wait. Speak to your vet and start treatment right away. And for affordable and effective parasite treatments, visit www.79pets.com.

Two sweet girlies decided to make our deck their home. Mosquitoes are a big problem where we live and we had to get them protected. This was the best bang for the buck. I’ve ordered from 79Pets several times and while delivery is not fast it is very consistent.

After Seresto collars failed to get rid of fleas, I didn't know where to turn. I saw a post on a page I follow (Kentucky Kitty Cats) saying that they use Nexgard Combo for the cats they shelter. I decided to try it and IT WORKS!

Customer photo review of Revolution Plus For Medium Cats 5.6-11 lbs (2.6-5kg)

Last year, I made a visit to the vet. I told them that Kattie/cat had ear mites. They gave me an ointment costing $80canadian. I used it up and purchased another bottle. $160. total not including the cost of the vet visit. No results. The ear mites have been there for a long time. Canadian vets have control of what is sold in Pet stores and you cannot purchase off the shelf products not recognized by them. I jumped at the chance to purchase your produce with a recommended 100% effectivity. I was willing to try, but was suspicions. After a month there was still a little scratching but after 6 weeks, the mites are gone and the scratching is gone. Thank you very much for this mite solution. I recommend it heartily. Harry P.S. Do not tell the Canadian vets as they will outlaw your product.
