How Does An Indoor Cat Get Worms?

You might think that your indoor cat is immune to worms since they never leave the comfort of your home. However, this is far from the truth. Worms are a common issue for felines, even those who never set foot outside. In this blog post, we’ll delve into the surprising ways indoor cats can contract worms and what you can do to prevent it.

Firstly, it’s essential to keep in mind that certain types of worms, such as tapeworms and roundworms, can be transmitted through fleas. Even if you don’t have any outdoor pets or rarely open your windows, fleas can still make their way inside on clothing or through other means. Once inside, they can pass on tapeworms and other parasites to your indoor cat.

Another common way indoor cats get worms is by consuming raw or undercooked meat. Some pet owners may offer this as a treat or part of a homemade diet without realizing that it could contain parasites like Toxoplasma gondii that could seriously harm their cat’s health.

So how do you protect your indoor cat from these pesky parasites? Stay tuned for our next post where we’ll share tips on preventing and treating worms in indoor cats. Remember – just because your cat stays indoors doesn’t mean they’re safe from these tiny terrors.

What are Worms?

Worms, those pesky parasites, are an unfortunate reality for our feline friends. As pet parents, it’s crucial to be knowledgeable about the different types of worms that can infect cats and how to prevent and treat infestations.

Tapeworms, one of the most common worms that infect cats, are flat and segmented with a length of several inches. These worms attach themselves to the lining of the small intestine and are usually transmitted when a cat ingests an infected flea or rodent. On the other hand, roundworms are long and thin and can grow up to several inches in length. These worms live in the small intestine and are typically contracted through contaminated soil or feces.

Hookworms are tiny, thin worms that attach themselves to the lining of the small intestine and feed on blood. They’re usually transmitted through contaminated soil or feces and can also pass from mother to kitten during nursing. Meanwhile, whipworms have thin, whip-like bodies, live in the large intestine, and are typically transmitted through contaminated soil or feces.

Worm infestations in cats can lead to serious health problems such as anemia, malnutrition, and even death if left untreated. Watch out for symptoms such as diarrhea, vomiting, weight loss, and a distended belly.

But don’t fret. There are ways to prevent and treat worm infestations in cats. Regular vet check-ups and deworming treatments can help keep your cat healthy and free from parasites. Maintaining good hygiene practices such as cleaning litter boxes regularly and washing your hands after handling your cat or cleaning up after them is also crucial.

It’s important to note that even indoor cats can get worms through contact with infected feces or animals. So, make sure to take preventative measures such as keeping the environment clean to reduce the risk of infection.

How do Indoor Cats Get Worms?

Despite popular belief, indoor cats are not entirely safe from parasites. In fact, they can get worms through various means, including contact with infected feces or soil. Curious by nature, cats may sniff, lick, or ingest contaminated soil or feces, allowing worms to enter their digestive system.

Another way indoor cats can contract worms is through the ingestion of infected prey. Even if your cat is indoors, they may still catch and eat insects, mice, or other rodents that may carry parasites. If these animals are infected with worms, then your cat can easily become infected as well.

Contaminated water sources are also a risk for indoor cats. Cats who drink from contaminated water sources run the risk of ingesting worm larvae and becoming infected. It’s important to be mindful of where your cat drinks from and ensure their water source is clean and free of contamination.

Believe it or not, even humans can unknowingly transfer worm eggs onto their indoor cats. Worm eggs can be brought in on shoes or clothing and transferred onto the cat’s fur or paws when they come into contact with us. This is another reason why it’s important to regularly wash our hands and keep our living spaces clean.

Ways in Which an Indoor Cat Can Contract Worms

Here are some details that explain the various ways in which an indoor cat can contract worms.

Exposure to Other Animals

While your indoor cat may not go outside, other animals can enter your home and leave behind contaminated feces. Your cat could come into contact with soil or litter contaminated with infected feces and subsequently ingest worm eggs.

To prevent this, keep your cat away from any potentially contaminated areas or animals. Regular deworming treatments can also help eliminate any worms your cat may have contracted.

Contaminated Food or Water

If your cat’s food or water bowls are not cleaned regularly, they could ingest worm eggs or larvae unknowingly. Additionally, raw meat that may be infected with worm larvae is also a potential source of worms for indoor cats.

Make sure to clean your cat’s food and water bowls daily and avoid feeding them raw meat. Instead, opt for cooked meat that has been properly prepared.

Environmental Factors

Indoor cats can come into contact with contaminated surfaces like carpets, rugs, or even soil from potted plants. Some species of worms can survive for extended periods in the environment and can infect your cat if they come in contact with them.

To prevent this, regularly clean your cat’s environment and consider using a pet-safe disinfectant to kill any potential worm larvae.

Mother-To-Kitten Transmission

Some types of worms can be passed down from mother cats to their kittens during pregnancy or through nursing. This means that even if a cat has never been exposed to other animals or contaminated food and water, they can still develop worms.

If you have a pregnant or nursing cat, make sure to take them to the vet for regular check-ups and deworming treatments.


Fleas can carry tapeworm larvae which can develop into adult tapeworms inside your cat’s intestine. Indoor cats can get fleas if they come into contact with other animals or if their environment is not kept clean.

To prevent flea infestations, regularly groom your cat and use flea preventative measures such as topical treatments or flea collars.

Contact with Infected Feces

One way indoor cats can become infected is through contact with contaminated feces. It’s important to note that even if your cat never goes outside, they can still get worms from exposure to contaminated areas, animals, food or water, environmental factors, mother-to-kitten transmission, and even fleas that carry tapeworm larvae.

Litter boxes are a common source of infection for indoor cats. If their litter box has been contaminated with worm eggs or if they come into contact with feces from other animals in the household, such as dogs or other cats, they can become infected with worms. Worm eggs can survive for months in the environment and are extremely resilient. They can be found in soil, on grass, and on surfaces that have been contaminated with feces. If an indoor cat comes into contact with any of these surfaces and then ingests the eggs while grooming themselves, they can become infected with worms.

Fleas are another way indoor cats can come into contact with infected feces. Fleas often carry tapeworm eggs and when a cat ingests a flea during grooming, they ingest the tapeworm eggs as well. Once inside the cat’s digestive system, tapeworms can grow to be several inches long and cause a variety of health problems.

To prevent your indoor cat from becoming infected by contaminated feces, there are several measures you can take. Firstly, keep litter boxes clean and practice good hygiene by washing your hands regularly after handling animals or cleaning litter boxes. Additionally, regularly deworming your cat and keeping them up to date on their vaccinations can help prevent other health issues that may arise from worm infections.

It’s important to note that not all worms are created equal. Some worms, like roundworms and hookworms, are more commonly found in cats than others. These worms can cause a range of symptoms such as vomiting, diarrhea, and weight loss. In severe cases, they can lead to anemia and even death. By taking preventative measures and keeping your indoor cat healthy, you can help ensure they live a long and happy life.

Contact With Infected Animals

Contact with infected animals is one of the most common ways that indoor cats can contract worms. Even if your cat never ventures outside, they may still come into contact with other animals that carry various types of parasites. Here are some tips to help reduce the risk of worm transmission from infected animals.

Rodents, birds, and other small animals can carry worms that can be transmitted to your cat through contact. If your cat catches and eats an infected animal, they can become infected as well. Indoor cats may also come into contact with contaminated surfaces or infected animals that find their way into your home.

Regularly cleaning and disinfecting areas where your cat spends time can help reduce the risk of worm transmission. This includes litter boxes, bedding, and any other areas where your cat may come into contact with contaminated surfaces.

Keep your cat up-to-date on their vaccinations and deworming medications. This will help protect them against a variety of infections, including those caused by contact with infected animals.

If you have multiple pets in your home, ensure all pets are treated for parasites simultaneously to prevent re-infection and reduce the spread of parasites between pets.

Mother Cats Transmitting Worms to Kittens

Unfortunately, mother cats can transmit worms to their kittens even before they are born. This is because worms can be passed through the placenta or mother’s milk. Kittens can also accidentally ingest worm eggs by coming into contact with contaminated feces from their mother or other infected animals.

Not all mother cats have worms, but it’s always better to be safe than sorry. Regular deworming of the mother cat and her kittens is crucial in ensuring their health and happiness. This is especially important if there are other pets in the household or if the kittens will be adopted to other families.

Symptoms of worm infestation in kittens include diarrhea, vomiting, weight loss, and a bloated belly. These symptoms can lead to serious health issues if left untreated, especially in young and immunocompromised animals. So, if you suspect that your kitten has worms, it’s best to consult a veterinarian immediately for proper diagnosis and treatment.

Here are some quick tips to protect your feline friend from worms:

  • Regularly clean your cat’s litter box to prevent contamination.
  • Keep your cat indoors as much as possible to reduce exposure to contaminated soil or surfaces.
  • Deworm your cat and her kittens regularly as recommended by your veterinarian.
  • Consult with your veterinarian about vaccinations and preventive measures.

By taking these preventive measures, you can reduce the risk of your kitten contracting worms from its mother or other infected animals.

Preventative Measures to Reduce Risk of Infection

Fortunately, there are several effective preventative measures you can take to reduce the risk of infection in your beloved pet.

One of the best ways to prevent your cat from getting infected with parasites is by keeping them indoors and away from other animals. This is especially crucial if you live in an area where outdoor cats are common. By keeping your cat indoors, you can significantly reduce their exposure to parasites and other diseases.

Another essential preventative measure is to keep the litter box clean. Maintaining a clean litter box not only promotes good hygiene for your cat but also helps prevent the spread of parasites. Be sure to regularly clean and change the litter box to minimize the risk of infection.

Feeding your cat a healthy and balanced diet is another critical factor in preventing infections. A diet rich in protein and fiber can help keep your cat’s digestive system healthy and less susceptible to infection. Choose high-quality cat food that meets all of your cat’s nutritional needs to ensure their well-being.

Additionally, maintaining good hygiene practices when handling your cat is vital. Washing your hands before and after handling your furry friend can help prevent the spread of parasites. Regular grooming of your cat can also help detect any signs of infection early on.

Finally, regular vet checkups and deworming treatments are crucial in preventing infections in cats. Your veterinarian can identify any potential health issues during checkups and recommend deworming treatments if necessary.

Symptoms of Worm Infestation in Cats

Even the most well-cared-for cats can fall victim to worm infestations. These pesky parasites can cause a range of symptoms in your cat, from mild to severe. So, what are the signs of worm infestation in cats that you need to look out for?

Firstly, it’s essential to understand the types of worms that can infect your cat. Cats are at risk of several types of worms, such as roundworms, tapeworms, hookworms, and whipworms. Each type of worm can cause different symptoms, making it crucial to identify the specific type of worm affecting your cat.

One of the most noticeable signs of a worm infestation is weight loss. If you’ve noticed that your cat has lost weight despite eating the same amount of food, it could be due to worms consuming the nutrients your cat needs to stay healthy.

Another symptom to be aware of is diarrhea. If your cat’s stool is loose and has a foul odor, it could be a sign that they have worms. In severe cases, your cat may also vomit or struggle when defecating.

Cats with worm infestations may also have a bloated or distended abdomen. This can occur due to the worms themselves or fluid buildup in the abdomen caused by the infection.

Other symptoms include a dull coat, lethargy, and a lack of appetite. Your cat may also scratch or lick their anus more than usual due to irritation from the worms.

It’s worth noting that not all cats with worm infestations will display these symptoms. Some cats may not show any signs at all, while others may only have one or two mild symptoms.


In conclusion, don’t let the misconception fool you – indoor cats are not immune to worms. These pesky parasites can find their way into your feline friend’s body through various means. Fleas, contaminated food or water, environmental factors, contact with infected feces, and exposure to infected animals are all potential sources of worm infestations in indoor cats.

The consequences of a worm infestation can be severe, leading to anemia and malnutrition if left untreated. Therefore, it’s crucial to take preventative measures such as regular vet checkups, deworming treatments, and maintaining good hygiene practices.

To minimize the risk of infection in your cat, keep them indoors as much as possible and ensure that their litter box is always clean. Feeding them a healthy diet is also essential for their overall health. When handling your cat, practice good hygiene practices such as washing your hands before and after petting them.

It’s also important to be aware of the symptoms of worm infestations in cats such as weight loss, diarrhea, bloated abdomen, dull coat, lethargy and lack of appetite. By knowing these signs and taking prompt action when necessary, you can help ensure that your cat receives the care they need.
