Cats often get worms. It’s a common problem. Worms are parasites that live inside your cat‘s body. They steal nutrients and can make your cat sick. As a cat owner, you need to know about worms. You should learn how to spot them and treat them.
There are several types of worms that affect cats. Some are more dangerous than others. All worms need treatment. Left untreated, worms can cause serious health issues. Some worms can even spread to humans. That’s why treating worms is so important.
In this guide, I’ll explain everything about cat worms. You’ll learn about different worm types, symptoms, treatments, and prevention. This information comes from years of experience and research. Let’s help keep your cat worm-free and healthy.
Common Types of Worms in Cats
Roundworms
Roundworms are the most common cat worms. They look like spaghetti. Adult roundworms can grow up to 5 inches long. Kittens often get roundworms from their mother’s milk. Cats can also get them by eating infected rodents.
Roundworms live in the cat’s intestines. They feed on digested food. A heavy roundworm infection can make a kitten very sick. The belly may look swollen. The cat might vomit worms or have diarrhea.
Tapeworms
Tapeworms are long, flat worms made of segments. These segments look like rice grains. You might see them near your cat’s rear or in the litter box. Cats get tapeworms by eating fleas or infected prey.
Tapeworms attach to the intestinal wall. They can grow very long. While not usually life-threatening, they rob nutrients. Tapeworms can make your cat’s coat look dull. The cat may scoot its bottom on the ground.
Hookworms
Hookworms are small but dangerous. They hook onto the intestinal wall and drink blood. This can cause anemia, especially in kittens. Cats get hookworms through the skin or by eating infected animals.
Hookworm infections can be serious. Symptoms include bloody diarrhea, weight loss, and weakness. The cat’s gums may look pale from blood loss. Hookworm larvae can penetrate human skin too.
Whipworms
Whipworms are less common in cats. They live in the large intestine. Whipworms cause chronic diarrhea and weight loss. Diagnosis can be tricky because they shed few eggs.
Heartworms
Heartworms live in the heart and lungs. Mosquitoes spread them. Heartworm disease is serious and can be fatal. Symptoms include coughing, difficulty breathing, and lethargy. Prevention is much easier than treatment.
Symptoms of Worms in Cats
How do you know if your cat has worms? Look for these signs:
- Visible worms in stool or vomit
- Diarrhea or bloody stool
- Weight loss despite good appetite
- Pot-bellied appearance (especially in kittens)
- Dull, rough coat
- Scooting or excessive licking of the rear
- Vomiting
- Lethargy or weakness
- Pale gums (sign of anemia)
- Coughing (possible heartworms)
Some cats show no obvious symptoms. That’s why regular fecal checks are important. Kittens with worms may fail to grow properly. Severe infections can be life-threatening.
Diagnosing Worms in Cats
If you suspect worms, see your vet. Diagnosis usually involves:
Fecal Examination
The vet will check a stool sample under a microscope. They look for worm eggs. This test finds most worm types. Sometimes multiple samples are needed.
Blood Tests
Blood tests can detect heartworms. They also show anemia from hookworms. Some tests check for antibodies to certain worms.
Physical Exam
The vet will examine your cat thoroughly. They’ll check weight, coat condition, and belly. They’ll look for signs of illness.
Imaging
In severe cases, X-rays or ultrasound may be needed. These can show large worm burdens or heartworms.
Tell your vet about any symptoms you’ve noticed. Mention if your cat goes outdoors or hunts. This information helps with diagnosis.
Treatment Options for Worms in Cats
Treatment depends on the worm type. Many safe, effective medications exist. Never use dog wormers on cats – some are toxic to felines.
Deworming Medications
Pyrantel Pamoate：
This treats roundworms and hookworms. It paralyzes the worms so they pass in stool. It’s safe for kittens and pregnant cats.
Praziquantel：
This kills tapeworms. It dissolves the worms inside the body. Often combined with other dewormers.
Fenbendazole：
A broad-spectrum dewormer for roundworms, hookworms, and some tapeworms. Given for several days.
Selamectin and Moxidectin：
Topical treatments that prevent some worms and parasites. Also kills fleas that carry tapeworms.
Milbemycin Oxime：
Prevents heartworms and treats some intestinal worms. Given monthly.
Treatment Protocols
Roundworms: Usually treated with pyrantel or fenbendazole
Tapeworms: Praziquantel is most effective
Hookworms: Pyrantel or fenbendazole work well
Whipworms: Fenbendazole for several days
Heartworms: Complex treatment requiring vet supervision
Most treatments need repeating. This kills newly hatched worms. Follow your vet’s instructions exactly. Some worms require multiple doses weeks apart.
Natural Remedies (With Caution)
Some people try natural worm treatments. These may include:
- Pumpkin seeds (contain cucurbitacin)
- Diatomaceous earth (food grade)
- Certain herbs like wormwood
These methods lack scientific proof. They may help prevent worms but often can’t treat active infections. Always consult your vet before trying natural remedies. Severe worm infections need proven medications.
Home Care During Treatment
While treating worms, provide good care:
- Keep the litter box very clean
- Wash bedding in hot water
- Give all medication as directed
- Monitor for side effects like vomiting
- Offer high-quality food to help recovery
- Keep treated cats indoors to prevent reinfection
- Separate infected cats from others if possible
Most cats feel better quickly after deworming. Kittens may need nutritional support. Watch for ongoing symptoms and report them to your vet.
Preventing Worms in Cats
Prevention is easier than treatment. Follow these tips:
Regular Deworming
Kittens should be dewormed every 2-3 weeks until 12 weeks old. Adult cats need regular deworming based on risk. Outdoor cats need more frequent treatment.
Flea Control
Fleas spread tapeworms. Use vet-approved flea prevention monthly. Treat the home environment too.
Clean Environment
Scoop litter boxes daily. Disinfect them regularly. Keep yards free of feces where worms can spread.
Prevent Hunting
Hunting rodents and birds exposes cats to worms. Keep cats indoors or supervise outdoor time. Bell collars may help reduce hunting success.
Heartworm Prevention
Give monthly heartworm prevention in mosquito areas. This is crucial in warm climates.
Proper Hygiene
Wash hands after handling cats or cleaning litter boxes. Wear gloves when gardening where cats may defecate.
Regular Vet Checks
Annual fecal exams catch worms early. Wellness visits help maintain overall health.
Special Considerations
Kittens
Kittens are especially vulnerable to worms. They can get roundworms from their mother before birth or through milk. Heavy worm loads can stunt growth or even kill kittens. Start deworming at 2-3 weeks old and repeat every 2-3 weeks until 12 weeks. Then continue monthly until 6 months old.
Pregnant Cats
Pregnant cats should be dewormed carefully. Some medications are safe during pregnancy. This reduces worms passed to kittens. Consult your vet for proper protocols.
Multi-Cat Homes
In homes with many cats, worms spread easily. Treat all cats simultaneously. Clean the environment thoroughly. Isolate new cats until dewormed.
Outdoor Cats
Outdoor cats have higher worm risks. They hunt and encounter other animals’ feces. Monthly broad-spectrum deworming is often recommended. Regular fecal checks help monitor worm status.
When to See the Vet
Most worm treatments are available over-the-counter. But see your vet if:
- Symptoms persist after treatment
- The cat is very young, old, or sick
- You see blood in stool or vomit
- The cat becomes weak or stops eating
- You suspect heartworms
- Over-the-counter treatments fail
- You’re unsure what type of worms are present
Severe worm infections need professional care. The vet may give injectable medications or supportive care like fluids. Some cases require hospitalization.
Human Health Risks
Some cat worms can infect humans:
- Roundworm larvae can migrate in people, causing organ damage
- Hookworm larvae can burrow under human skin
- Tapeworms can rarely infect people, especially children
Good hygiene prevents most risks:
- Wash hands after handling cats or litter
- Keep children’s sandboxes covered
- Wear shoes outdoors
- Clean litter boxes daily (pregnant women should avoid this)
- Treat cat worms promptly
Healthy adults have low risk, but children and immunocompromised people are more vulnerable. Regular deworming protects both cats and humans.
Myths About Cat Worms
Let’s clear up some common misconceptions:
Myth: Indoor cats can’t get worms.
Truth: They can get worms from fleas, contaminated soil, or infected prey that gets inside.
Myth: Garlic kills worms in cats.
Truth: Garlic is toxic to cats and ineffective against worms.
Myth: You only need to deworm when you see worms.
Truth: Many worms aren’t visible. Regular prevention is better.
Myth: Over-the-counter dewormers are always enough.
Truth: Some worms need prescription medications.

Cost of Worm Treatment
Worm treatment costs vary:
Fecal exam: 25−50
Basic dewormer: 10−20
Prescription medications: 20−100
Heartworm treatment: 500−1500
Prevention costs much less than treatment. Many monthly flea/heartworm preventatives also control some intestinal worms. Ask your vet about cost-effective options.
Long-Term Health Effects
Chronic worm infections can cause:
- Poor growth in kittens
- Chronic diarrhea
- Malnutrition
- Anemia
- Intestinal blockages (rare)
- Lowered immunity
