Cats, like many animals, are susceptible to parasitic infections. Among the most common and concerning are worms, which can significantly impact a cat’s health if not detected and treated in a timely manner.
In this article, we’ll explore the different types of worms that can affect cats, how they get infected, the symptoms to watch for, and how to protect your feline friend from these parasites.
What Are Worms?
Worms are parasitic organisms that can live inside your cat’s body, feeding off its nutrients and causing damage to its organs. The most common types of worms that affect cats are roundworms, tapeworms, hookworms, and whipworms. These worms can cause a variety of health issues, from digestive disturbances to more severe conditions such as anemia or organ damage.
Roundworms
Roundworms (Toxocara cati) are among the most common parasitic worms found in cats. These long, spaghetti-like worms are usually found in the small intestine. Kittens are particularly vulnerable to roundworm infections, but adult cats can also contract them. Roundworms can be transmitted through contaminated soil, feces, or infected prey.
Tapeworms
Tapeworms (Dipylidium caninum) are flat, segmented worms that can grow quite long. These worms usually inhabit the small intestine of cats. Tapeworms are typically transmitted when a cat swallows an infected flea or other intermediate host. The segments of the worm, which contain eggs, can be seen in the cat’s feces or around the anus, often moving like little grains of rice.
Hookworms
Hookworms (Ancylostoma tubaeforme) are less common in cats than roundworms or tapeworms but can still pose a significant health risk. Hookworms latch onto the walls of the cat’s small intestine and feed on its blood, which can lead to anemia. These worms are transmitted through contaminated soil or feces and can even enter a cat’s body through its skin.
Whipworms
Whipworms (Trichuris vulpis) are rare in cats but can be found in certain areas. They are thin, thread-like worms that live in the colon and rectum. Whipworms can cause diarrhea and weight loss. These worms are usually contracted through ingestion of contaminated soil, water, or feces.
How Do Cats Get Worms?
There are several ways in which a cat can become infected with worms. Some of the most common methods of transmission include:
1. Ingestion of Infected Prey
Cats are natural hunters, and they may consume infected rodents, birds, or other small animals that carry worm larvae. For example, a cat may ingest a flea-infested rodent, thus contracting tapeworms.
2. Contaminated Feces or Soil
Cats can pick up worm eggs from contaminated environments, including feces or soil. This is particularly common in outdoor cats that come into contact with infected animals’ droppings. Kittens can also be infected by licking or grooming their mother, who may harbor roundworm larvae.
3. Fleas
Fleas are the primary carriers of tapeworms. If a cat ingests a flea while grooming, it may end up with a tapeworm infection. This is one of the reasons why flea control is important in preventing worm infestations.
4. Mother to Kitten Transmission
Kittens are often born with roundworms because the larvae can be passed from the mother during pregnancy or through her milk. This is why young kittens need to be dewormed early in life.
5. Contact with Infected Soil or Water
In areas with poor sanitation, cats may ingest worm larvae present in contaminated water or soil. This is a common route for hookworms and whipworms.

Symptoms of Worms in Cats
The symptoms of worm infestations can vary depending on the type of worm, the severity of the infection, and the overall health of the cat. However, some common signs to look out for include:
1. Vomiting
Vomiting, particularly when the cat is bringing up worms or segments of worms, is a common sign of an intestinal worm infection. You may notice worms in the vomit or around the cat’s mouth.
2. Diarrhea
Infections like roundworms and hookworms can cause diarrhea, sometimes with blood. If your cat’s stool is unusually runny or has a foul odor, it may be a sign of a worm infestation.
3. Weight Loss and Poor Coat Condition
Worms, especially roundworms and tapeworms, can deprive your cat of essential nutrients, leading to weight loss, lethargy, and a dull, rough coat. Your cat may appear unkempt, even though they are eating normally.
4. Scooting
If your cat is scooting on its bottom, it could be a sign that it is irritated by worms, particularly tapeworms. The segments of the tapeworm can cause itching around the anus, prompting the cat to drag its rear on the ground in an attempt to relieve the discomfort.
5. Visible Worm Segments or Eggs
Sometimes, you can actually see worms or their segments in your cat’s stool or around its anus. Tapeworm segments may look like small grains of rice, while roundworms may appear as long, thin, and white threads.
6. Coughing
In severe cases of roundworm or hookworm infestations, a cat may cough or exhibit respiratory symptoms. This occurs when the larvae migrate through the lungs, causing irritation.
7. Anemia
Hookworms feed on blood and can cause anemia in your cat. Symptoms of anemia include pale gums, weakness, and lethargy.
How to Diagnose Worms in Cats
If you suspect your cat has worms, it’s essential to visit a veterinarian. The vet will perform a thorough physical examination and may recommend one or more of the following diagnostic tests:
- Fecal examination: This is the most common method for diagnosing worms. The vet will examine a stool sample for the presence of worm eggs or larvae.
- Blood tests: If your cat has severe symptoms, a blood test may be conducted to check for anemia or other complications caused by worm infestations.
- Fecal floatation: This test helps detect worm eggs that may not be visible in a normal fecal examination.
Treatment Options for Worms in Cats
If your cat is diagnosed with worms, don’t panic—worm infestations are treatable with medication. The treatment plan will depend on the type of worm your cat is infected with:
- Deworming medication: Your vet may prescribe oral or injectable dewormers. These medications are designed to kill worms in your cat’s intestines. Some medications target specific types of worms, while others are broad-spectrum and can treat multiple types of parasites.
- Topical treatments: For tapeworms, a flea control regimen may be required to prevent re-infection. In some cases, vets will recommend topical dewormers that target tapeworms.
- Follow-up treatment: Some cats may need a second round of deworming after two to three weeks, especially if they were heavily infested.
Preventing Worms in Cats
Prevention is the best approach to protecting your cat from worms. Here are some strategies to reduce the risk of infection:
1. Regular Deworming
Kittens should start deworming treatments as early as 2 weeks of age, with follow-up treatments every few weeks. Adult cats should also be dewormed regularly, typically every 3 to 6 months, as recommended by your vet.
2. Flea Control
Since fleas are the primary carriers of tapeworms, it’s crucial to keep your cat on a consistent flea prevention program. This includes both topical treatments and oral medications.
3. Limit Outdoor Exposure
While outdoor cats are at a higher risk for worm infections, indoor cats can also become infected. However, keeping your cat indoors minimizes their exposure to contaminated soil, feces, and other animals. If your cat does go outside, try to limit their exposure to areas where other animals frequent.
4. Good Hygiene
Maintaining a clean environment is essential in preventing worm infestations. Regularly clean your cat’s litter box and remove any feces promptly to avoid contamination. Also, keep your home and yard free from animal waste.
5. Regular Vet Checkups
Routine veterinary checkups allow your vet to catch any early signs of worm infestations and provide the necessary treatment before the problem worsens.
