Large Roundworms in Cats; Symptoms, Treatments, and Vaccines


Large roundworms in Cats are frequently found, which are intestinal parasites. Cats are commonly infected by Toxocara cati and Toxascaris leonine, two types of roundworms. These nematode-related parasites can harm your health if you don’t treat them. Cats get infected by eating roundworm eggs or larvae, which are frequently present in the environment in places like soil or excrement.

Large Roundworms in Cats

Cat roundworms usually have a long, cylindrical shape and are white or pale. They are frequently compared in appearance to spaghetti or noodles. Roundworms that are adults can range in length from a few inches to several inches. The worms may be visible to the naked eye and appear as long, segmented strands when passed in the cat’s feces.

Symptoms of Roundworms in Cats:

Roundworms in cats can cause various symptoms, which a cat may display. These signs could consist of the following:

  • Cats with roundworms may vomit or experience recurring vomiting attacks.
  • Cats with an infection may develop diarrhea, which occasionally contains blood.
  • The cat may create a “potbellied” appearance due to the enlargement or swelling of its abdomen by roundworms.
  • Cats with roundworms may have dull, scratchy, or unmaintained coats.
  • Infected cats may lose weight or have trouble putting on weight.
  • Cats with roundworm infections may appear passive, without excitement or vitality.
  • Worms: In extreme circumstances, it’s possible to see live roundworms in the cat’s feces or vomit.

Causes of Large Roundworms in Cats

Cats can contract roundworms in many different ways:

  • Cats can contract roundworms by taking in parasite-infected prey animals like rodents or birds.
  • Roundworm eggs can contaminate soil because they are excreted in the feces of diseased animals. Cats might contract the infection by consuming these eggs while grooming or eating grass.
  • Roundworm larvae can be passed from mother to kitten by pregnant cats through the placenta or the milk while the kittens are feeding.

Diagnosis of Roundworms in Cats:

To identify roundworms in cats, a vet may carry out the following procedures:

Fecal Examination: 

A tiny sample of the cat’s waste is analyzed under a microscope. This makes it possible for the vet to find roundworm eggs or adult worms.

Physical Exam: 

The vet may physically examine the cat for symptoms like a swollen abdomen or an unclean coat.

Blood Tests: 

Blood tests may occasionally evaluate the cat’s general health and find any anomalies linked to a roundworm infestation.

Prognosis of Large Roundworms in Cats:

With the right care, cats with roundworm infestations typically have a favorable prognosis. Most cats can fully recover from their illnesses and respond well to therapy. The degree of the infestation, the cat’s general health, and any underlying disorders that could make treatment difficult can all affect the prognosis. Early discovery and rapid treatment increase the likelihood of a favorable outcome.

Treatment for Roundworms in Cats:

Treatment for Roundworms in Cats

In most cases, a combination of medicine, preventative measures, and environmental management is used to treat cats with roundworms. The available therapies include:

Deworming Medicines

A veterinarian-prescribed deworming medicine is the main treatment for cat roundworms. These drugs work well to eliminate adult worms and stop new infections. The cat’s age, weight, and health status determine the precise prescription and dosage. They are available in various formats, including pills, topical solutions, and injections.

Repeated Therapy:

Sometimes, deworming just once might not eliminate all the worms. Particularly in severe infestations, numerous treatments can be required to guarantee total eradication.

Preventive actions

Building a preventive care regimen to avoid reinfection and safeguard against future infestations is crucial. As advised by the vet, frequent deworming at the right intervals can help stop recurrence. Furthermore, reinfestation can be avoided by maintaining a clean-living space and engaging in excellent hygienic practices, including disposing of cat waste properly.

Environmental Management: 

Cleaning and disinfecting the cat’s living space, including bedding and litter boxes, can help eliminate any potential roundworm eggs. Eliminating excrement from the surroundings regularly lowers the chance of illness. Roundworm eggs can survive in the environment for extended periods. Thus, thorough cleaning and efficient waste disposal are essential.

A veterinarian must be consulted to diagnose accurately and choose the best course of action for your cat. To guarantee the best possible outcome for your cat’s health, they may advise you on the precise medications and dosage and offer suggestions for preventive measures and environmental management.

Recovery and Management of Roundworms in Cats:

Recovery from large roundworm in cats’ infections with the right care and precautions. The veterinarian’s recommended deworming treatment works well to eliminate adult worms. It’s crucial to remember that reinfection may occur if preventive actions are not taken. Therefore, it’s imperative to maintain good hygienic habits and continue frequent deworming as the veterinarian advises. For your cat’s long-term well-being, it’s also crucial to monitor their health and act quickly if there are any indications of reinfection or other health problems.

Vaccinations and Prevention for Roundworms in Cats

Vaccinations and Prevention for large Roundworms in Cats

Several precautions must be taken to prevent cat roundworm infestations:

Regular Deworming:

Following your veterinarian’s advice for a regular deworming program can help avoid roundworm infestations. Starting at a young age, kittens should be dewormed, and older cats should be regularly dewormed depending on their lifestyle and risk factors.

Environmental Hygiene:

Keeping your cat’s living space clean is important. Feces should be promptly removed from litter boxes and properly disposed of. Regularly maintain your cat’s litter box and other frequented areas clean and germ-free. Don’t expose your cat to any soil or animal feces that could be polluted.

Reduce Hunting and Exposure:

Cats with access to the outdoors have a higher chance of meeting diseased animals or contaminated areas. The likelihood of contracting roundworms can be decreased by minimizing hunting activity and, if necessary, offering a secure, regulated outdoor environment. Furthermore, avoiding contact with stray or unknown cats can aid in limiting the spread of roundworms.


Although there is no specific vaccine to prevent roundworms in cats, following the schedule of recommended vaccinations for your cat can help shield them from other contagious infections. Routine vaccines can help you stay healthy overall and build up your immune system, which can help you fight off illnesses like roundworms.

Conclusion Regarding Large Roundworms in Cats:

Cats are frequently infected with roundworms, an intestinal parasite. They are often long, white, or pale worms that look like spaghetti and are excreted by cats or discovered in their vomit. Vomiting, diarrhea, a plump appearance, a bad coat condition, lethargy, weight loss, and worms in feces or vomit are all signs of roundworm infestation. Cats can contract roundworms by eating infected animals or polluted soil, and kittens can catch the parasite from their mothers. Fecal examination, physical examination, and occasionally blood tests are used in the diagnosis process.

Roundworms are treated with a veterinarian-prescribed dewormer, maybe more than once, and with preventive measures such as routine deworming, environmental hygiene, and limiting exposure to contaminated areas. With the right care, the prognosis for roundworm infestations is typically favorable. Roundworm infestations in cats can be avoided with preventative measures such as routine deworming, good hygiene habits, and limiting exposure to probable infection sources.

To protect your cat’s health and well-being, you should see a veterinarian for an accurate diagnosis, treatment suggestions, and advice on preventive care.

How do you get rid of roundworms in cats?

It is best to visit a veterinarian for an accurate diagnosis and treatment plan to eliminate cat roundworms. Roundworms are typically treated with deworming drugs that a veterinarian prescribes. The drug works well to kill adult worms. Particularly in severe infestations, numerous treatments can be required to guarantee total eradication. It’s crucial to adhere to the veterinarian’s medicine delivery and dosage recommendations. Additionally, it’s essential to maintain a clean living space and practice excellent hygiene, such as properly disposing of cat waste.

Are cat roundworms harmful to humans?

Cat roundworms can indeed be dangerous to people. Direct transmission from cats to humans is uncommon, as most human infections happen due to ingesting contaminated soil or coming into touch with infected animal excrement.
However, roundworm larvae can spread to different organs and harm someone if they unintentionally consume the eggs. Visceral larva migrans is the medical term for this. To reduce the danger of roundworm transmission to humans, practicing proper hygiene, such as completely washing hands after handling cat excrement and keeping one’s living space clean, is critical.

Can cats survive roundworms?

Yes, with the right care, cats can survive roundworm infestations. Particularly in cases of severe infection, roundworms can harm cats’ health and cause them discomfort. However, most cats can recover fully with prompt diagnosis and appropriate care, including deworming medicine recommended by a veterinarian. To reduce the chance of reinfection and preserve the cat’s general health, routine deworming, and preventive actions are crucial.

Can you treat roundworms in cats at home?

Treating cats at home for roundworms without visiting a veterinarian is not advised. Although there are over-the-counter deworming drugs, a veterinarian’s diagnosis and treatment plan should always be followed. The kind and intensity of the infestation may be precisely determined by veterinarians, who can also recommend the right deworming drug and dose for your cat. A veterinarian can also offer advice on preventive care, hygienic habits, and managing your cat’s general health.

Is roundworm easy to treat in cats?

Cats with roundworm infestations can be successfully treated with the right veterinarian care. Veterinarian-prescribed deworming drugs are typically successful in eliminating adult worms and curing the infection. The degree of the infestation and the cat’s general health could affect how straightforward the therapy is. Successful treatment depends on the veterinarian’s advice for medicine administration, dosage, and any additional measures. Future infestations can be avoided with regular monitoring and protective measures.

Do roundworms make cats hungry?

Cats with roundworm infestations can experience increased hunger or an insatiable appetite. The cat’s capacity to efficiently absorb nutrients may be hampered by the worms’ consumption of the cat’s intestine’s nutrients. To make up for the nutrient loss, the cat may become more hungry as a result. It’s crucial to remember that not all cats with roundworms may exhibit increased appetite. From one cat to the next, symptoms and actions can differ.

Do cats with roundworms experience pain?

The presence of roundworms does not immediately hurt cats. However, cats may experience discomfort or stomach pain in the event of severe infestations or problems brought on by the infestation. An abundance of worms in the intestines might bring blockages or inflammation, resulting in discomfort or pain. Other underlying pain or discomfort signs could include vomiting, diarrhea, or a plump appearance. Appropriate medication and prompt veterinarian care can help resolve these problems.

Can my cat be dewormed by myself?

Although there are over-the-counter deworming drugs for cats, it is typically advised to speak with a veterinarian before deworming. Veterinarians are qualified to determine the infestation’s type and extent and provide your cat with the right deworming drug and dosage. Additionally, they can offer advice on preventative care, general health management, and any underlying medical concerns. By seeking the advice of a vet, you can be sure that your cat will receive the greatest care and attention available for its unique needs.
