Discovering that your feline friend might have worms can be unsettling for any cat owner. These parasites, whether internal or external, can significantly impact your cat’s health and well-being. Understanding how to identify if your cat has worms is the first step in ensuring they receive prompt and effective treatment. This guide will walk you through the signs, symptoms, and what you need to know to protect your cat from these unwelcome guests.
Common Types of Worms in Cats and How to Spot Them
Several types of worms can affect cats, each with its own characteristics and ways of manifesting. Being familiar with these common worms can help you better understand what to look for.
-
Roundworms: As the most prevalent intestinal parasites in cats, roundworms are often visible to the naked eye. These worms can grow to be three to five inches long and resemble spaghetti. You might notice them in your cat’s vomit or feces. They live in the small intestine, consuming nutrients from your cat’s food. Keep an eye out for white, string-like objects in your cat’s stool, which could be these worms.
-
Tapeworms: Tapeworms are another common internal parasite. While inside the intestine they are flat and ribbon-like, you’re more likely to identify them by their segments. These segments look like small grains of rice or sesame seeds and can be seen in your cat’s feces or around their anus. Cats typically get tapeworms from swallowing fleas carrying tapeworm eggs, often during grooming, or by eating infected rodents or birds.
-
Hookworms: These are smaller internal parasites that are more harmful due to their feeding habits. Hookworms attach to the intestinal lining and feed on your cat’s blood using hook-like teeth. Infestation can occur through ingestion, skin penetration by larvae, or from mother to kittens. While hookworms themselves are not easily visible, they can cause anemia. Signs like pale gums and nose, and lethargy, can indicate a hookworm problem.
-
Heartworms: Heartworms are a serious concern as they can be fatal. They live in the heart, lungs, and blood vessels and are transmitted through mosquito bites. Unfortunately, there’s no cure for heartworm in cats, making prevention crucial.
-
Lungworms: Cats can contract lungworms by drinking contaminated water or eating infected prey like rodents or birds. These worms migrate to the lungs, causing respiratory issues that can mimic bronchitis or pneumonia. Symptoms are often subtle and easily mistaken for other respiratory conditions.
-
Whipworms: Though less common in cats, whipworms can cause significant issues. Cats get them by ingesting contaminated material containing whipworm eggs. Symptoms can include weight loss, digestive problems, and bloody diarrhea.
-
Stomach worms: These worms are spread through the vomit of infected cats and are more common in multi-cat households or roaming cats. Symptoms are similar to other gastrointestinal issues like vomiting, loss of appetite, and weight loss.
-
Bladder worms: Bladder worms are rare in cats and often show no noticeable symptoms. In severe cases, they might lead to signs resembling urinary tract infections.
-
Liver flukes: Liver flukes affect the liver, bile ducts, and small intestine. Cats get them through a complex cycle involving snails and secondary hosts like lizards or frogs. They are more common in subtropical regions.
It’s important to remember that ringworm is not a worm at all, but a fungal infection affecting the skin and hair.

Recognizing the Signs and Symptoms of Worms in Cats: What to Look For
Both indoor and outdoor cats of any age can get worms. Kittens can be born with worms or get them from their mother’s milk, while adult cats can contract worms from fleas, contaminated feces, or hunting. Knowing the symptoms is key to early detection.
Here are common signs that your cat might have worms:
-
Visible Worms: This is often the most direct sign. You might see whole worms or segments in your cat’s feces, vomit, or even around their anus, stuck in their fur. Roundworms look like spaghetti, while tapeworm segments resemble rice grains.
-
Changes in Coat Appearance: A dull, rough, or clumped coat can indicate a worm infestation. Worms steal essential nutrients, leading to poor coat health and potential dehydration.
-
Pale Gums: Healthy cat gums are pink. Pale or whitish gums can be a sign of anemia, which can be caused by blood-sucking worms like hookworms. Check your cat’s gums by gently lifting their lip.
-
Vomiting: While cats vomit for various reasons, increased or frequent vomiting could be a symptom of worms irritating their digestive system.
-
Changes in Stool: Diarrhea, especially if persistent, can be a sign of worms. Dark, tarry stool suggests digested blood, which is a serious indicator of hookworm infestation and internal bleeding.
-
Increased Appetite with Weight Loss: If your cat is eating more than usual but still losing weight, worms could be the reason. They are essentially stealing nutrients, leaving your cat hungry but unable to gain weight.
-
Scooting: You might notice your cat dragging their rear end across the floor. This behavior, known as scooting, can be a sign of irritation from tapeworm segments around the anus.
-
Swollen Belly: In kittens, a pot-bellied appearance can be a sign of a heavy roundworm infestation.
If you observe any of these symptoms, it’s crucial to consult your veterinarian immediately for a proper diagnosis and treatment plan.

How Cats Contract Worms: Understanding the Transmission
Understanding how cats get worms can help you take preventive measures. Here are the main ways cats become infected:
-
Fecal-Oral Transmission: Contact with infected feces is a primary route. This can happen when cats walk through contaminated soil or litter boxes and then groom their paws.
-
Ingestion of Infected Hosts: Hunting and eating rodents, birds, or reptiles that carry worm larvae can lead to infection. Fleas also act as intermediate hosts for tapeworms; when a cat grooms and swallows an infected flea, they can get tapeworms.
-
Mother to Kittens: Kittens can get worms from their mothers either in utero or through nursing.
-
Skin Penetration: Hookworm larvae can penetrate the skin, especially through the paws, leading to infection.
Can Cats Get Worms from Dogs?
Yes, cats can get certain types of worms from dogs, particularly roundworms and hookworms. This usually happens when a cat ingests dog feces that are contaminated with worm eggs or larvae. It’s important to prevent cross-species fecal contact to reduce the risk.
Are Worms Painful for Cats?
Worms can indeed cause discomfort and pain for cats. The severity depends on the type of worm and the level of infestation. Symptoms like vomiting, diarrhea, and abdominal cramping are directly painful. Additionally, as worm larvae migrate through organs, they can cause inflammation and further discomfort. Heavy infestations can lead to serious health issues and significant pain.
Diagnosing Worms in Cats: What to Expect at the Vet
While some worms are visible, diagnosis often requires veterinary testing. The primary method is a fecal exam.
- Stool Sample: Your vet will ask you to bring a fresh stool sample from your cat.
- Fecal Floatation: In the lab, the sample is mixed with a special solution that causes worm eggs to float to the surface, separating them from the feces.
- Microscopic Examination: A drop from the top of the solution is placed on a slide and examined under a microscope to identify the specific type of worm eggs present.
- Physical Exam and Blood Work: Your vet may also conduct a physical examination and blood tests to assess your cat’s overall health and check for signs like anemia.
Identifying the exact type of worm is crucial as it determines the appropriate medication and treatment plan. Post-treatment fecal exams are usually necessary to confirm the worms are eradicated.

Treating Worms in Cats: Getting Rid of Parasites
Fortunately, most intestinal worms in cats are easily treated with deworming medications.
- Dewormers: These medications are designed to kill both adult worms and larvae. They come in various forms, including pills, liquids, and topical treatments.
- Dosage and Course: Your vet will prescribe the appropriate dewormer and dosage based on the type of worm and your cat’s weight. Often, multiple doses are needed to break the worm life cycle. Follow your vet’s instructions carefully.
- Follow-up: A second dose is typically given to eliminate any worms that may have hatched after the initial treatment. For more persistent worms like hookworms or lungworms, a longer treatment course might be necessary.
Can Humans Get Worms from Cats? Understanding Zoonotic Risk
Yes, some worms that affect cats can be transmitted to humans, especially roundworms and hookworms. This typically happens through accidental ingestion of infected feces or contaminated soil.
- Transmission Routes: Gardening without gloves, walking barefoot in contaminated soil, or children playing in contaminated sandboxes are common ways humans can get worms from cats.
- Prevention: Good hygiene is essential. Wash your hands thoroughly after handling cat feces or being in areas where cats defecate. Wear gloves when gardening and ensure children’s play areas are clean.
Preventing Worm Infestations in Cats: Proactive Measures
Prevention is always better than cure. Here’s how to protect your cat from worms:
- Year-Round Flea Prevention: Since fleas transmit tapeworms, consistent flea control is crucial.
- Regular Deworming: For outdoor cats or hunters, preventative deworming every 3 months can help eliminate worms before they become a problem. Consult your vet about a suitable preventative deworming schedule.
- Maintain a Clean Litter Box: Daily cleaning of the litter box minimizes the risk of fecal-oral transmission.
- Proper Hygiene: Always clean up cat feces promptly, wash your hands after handling litter or being in contact with soil where cats might defecate, and wear gloves when cleaning litter boxes.
What Happens If Worms Go Untreated in Cats?
Leaving worm infestations untreated can lead to serious and even life-threatening health problems for your cat.
- Malnutrition: Worms steal vital nutrients, causing deficiencies and overall weakness.
- Severe Anemia: Hookworms and other blood-feeding worms can cause significant blood loss, leading to severe anemia.
- Intestinal Obstructions: Heavy worm burdens can cause blockages in the intestines.
- Organ Damage: Some worms, like heartworms and lungworms, directly damage vital organs.
Prompt treatment is essential to avoid these severe complications and ensure your cat’s health and well-being.
Summary: Keeping Your Cat Worm-Free
Worms are a common issue in cats, but being informed and proactive can make a big difference. Recognizing the signs and symptoms, understanding transmission, and taking preventive measures are key to protecting your feline companion. If you suspect your cat has worms, don’t hesitate to consult your veterinarian. With prompt diagnosis and treatment, your cat can quickly return to being healthy and worm-free!
