Cats can get parasites through various means, including contaminated food, water, and soil. Fleas, ticks, and mosquitoes are common vectors of parasites.
Direct contact with an infected animal is another way cats can pick up parasites. This can happen at the vet's office, a park, or even a neighbor's yard.
Even a simple scratch from a contaminated surface can lead to parasite transmission. For example, if your cat scratches a flea-infested bush, they may ingest the flea's eggs or larvae.
Prevention is key to keeping your cat safe from parasites.
Common Parasites and Infections
Cats can get a variety of parasites that can cause problems for their health and well-being. Intestinal worms, such as roundworms, are a common issue in cats.
One of the most common signs of an intestinal worm infection in cats is diarrhea and vomiting. You might also notice spaghetti-like worms in your cat's stool or vomit.
Roundworm parasites are the most common type of worm that infects cats. They can enter your cat's intestinal tract when they drink their mother's milk as a kitten or through contact with contaminated soil or litter.

Coccidia are tiny, single-celled parasites that live in a cat's intestinal wall. They're not technically worms, but they're a common intestinal parasite in cats.
Kittens are more susceptible to coccidia infection, but adult cats can become infected too. Cats can get coccidia by eating contaminated feces or infected rodents.
If your cat has an intestinal worm infection, you might notice weight loss, a bloated belly, coughing, or dehydration. In severe cases, these infections can be life-threatening.
Here are some common parasites and infections that cats can get:
- Roundworms: enter the intestinal tract through contaminated milk, soil, or litter
- Coccidia: tiny, single-celled parasites that live in the intestinal wall, infect through contaminated feces or rodents
How Cats Get Infected
Cats get infected with worms through various means. One way is by being passed on through feces.
Cats can also ingest an infected host, such as a bird, rodent, reptile, or insect, while hunting or scavenging. This can happen when they groom themselves and swallow the fleas.
Kittens can become infected by drinking their mother's milk, which can contain roundworm parasites.
How to Get Infected

Cats can get infected with worms through various means, including being passed on through feces, ingesting an infected host, and grooming themselves after coming into contact with fleas.
Feces can contain parasite eggs or larvae that can infect your cat if they ingest them.
Kittens can become infected with roundworms through their mother's milk, while adult cats can become infected through contact with contaminated environments or infected animals.
Coccidia parasites can be found in contaminated feces or infected rodents, which can then be ingested by your cat.
Fleas can carry the larval form of tapeworms, and if your cat grooms themselves after coming into contact with infected fleas, they can ingest the parasites.
Rodents, rabbits, birds, and insects can eat parasite eggs, but these eggs remain dormant in their bodies until a cat consumes them, at which point they can grow into adult worms.
If your cat is dealing with a flea infestation, they're at risk of picking up an intestinal worm, especially tapeworms, through the process of grooming themselves or other cats.
Cats are especially at risk for tapeworms because they are meticulous groomers, often ingesting any fleas present during grooming.

How Coccidia Affects Pets
Coccidia can be a serious issue for cats, especially kittens. They can live in a cat's intestinal wall and cause a range of problems.
Kittens are more susceptible to serious complications because their immune systems are weak. If infected, they can experience severe infestation, leading to extreme cases of diarrhea, vomiting, dehydration, or even death.
Infected cats may show no signs or symptoms at all. This can make it difficult to detect the issue, but regular fecal testing can help catch it early.
The most common clinical sign of coccidia is diarrhea. This can be a sign that your cat needs attention, so keep an eye out for changes in their stool.
Coccidia can be passed onto other animals through contaminated feces or infected rodents. This is why it's so important to keep your pet's surroundings clean and free of contamination.

Will Hook Affect My?
Hookworms can be a serious threat to young or malnourished kittens that may not be able to survive the blood loss without a transfusion at a hospital and extensive follow-up care.
Hookworms feed on your cat's blood, resulting in blood loss and anemia.
Adult cats can also experience diarrhea and weight loss due to hookworm infestation.
Hookworms can cause anemia in cats, which can be a life-threatening condition if left untreated.
The severity of hookworm infestation can vary depending on the number of worms and the overall health of the cat.
Types of Parasites
Cats can get a variety of parasites, including worms and other types of organisms that can cause harm.
Tapeworms, for example, are a common type of parasite found in cats. They can be identified by the grains of rice-like segments that appear around a cat's anus or in their feces.
These segments are actually mature tapeworms that have been released from the cat's body. To complete their life cycle, tapeworms need an intermediate host, such as a mouse, to eat the eggs from the environment, and then the cat will become infected.
Some common types of tapeworms that infect cats include Dipylidium caninum and Taenia taeniaeformis.
Here are some common types of worms that can infect cats:
- Tapeworms
- Hookworms
- Roundworms
- Whipworms
- Heartworms
- Liver flukes
- Stomach worms
- Bladder worms
- Lungworms
The Types of Parasites
Roundworms are the most common intestinal parasites in cats of all ages around the world. They can survive for several years in the environment and are passed from mother cats to kittens through her milk. Roundworms attach to the lining of the intestinal tract and feed on the blood of their host, causing a range of symptoms including weight loss, vomiting, and diarrhea.
Tapeworms, on the other hand, are long, flat worms that can be found in a cat's stool or vomit. They have a segmented body and can be passed in the feces, or through the ingestion of infected fleas or rodents. Tapeworms need an intermediate host to complete their life cycle, and can be found in cats that hunt or have fleas.
Hookworms are another type of parasite that can infect cats, and can penetrate a cat's skin if they walk or lie down in a contaminated area. Hookworms can cause dark, tarry stool and anemia in cats.

Whipworms are less common, but can still cause significant health issues in cats. They attach to the lining of the intestinal tract and feed on the blood of their host, causing symptoms such as diarrhea and weight loss.
Other types of parasites that can infect cats include liver flukes, heartworms, stomach worms, bladder worms, and lungworms. These parasites can cause a range of symptoms, from mild to severe, and can be life-threatening if left untreated.
Here's a list of the most common types of parasites that can infect cats:
- Roundworms
- Tapeworms
- Hookworms
- Whipworms
- Liver flukes
- Heartworms
- Stomach worms
- Bladder worms
- Lungworms
Coccidia Infection in Pets
Coccidia are tiny, single-celled parasites that live in a cat's intestinal wall.
Kittens are more susceptible to coccidia infection, but adult cats can become infected as well. Cats become infected by eating contaminated feces or infected rodents.
Coccidia are shed in poop and then passed onto other animals, like your beloved family pet. This is why it's essential to keep your cat's surroundings clean and free of contamination.

Infected cats may show no signs or symptoms of these parasites at all. However, if infected, the most common clinical sign of coccidia is diarrhea.
Kittens are most susceptible to serious complications because their immune systems are weak. Severe infestation can result in extreme cases of diarrhea, vomiting, dehydration, or even death.
A routine fecal test is used to diagnose coccidia in cats. A sample of your pet's poop will be examined under a microscope for microscopic coccidia eggs and coccidia antigen.
Ensuring your pet's surroundings are clean and free of contamination is one step in preventing coccidia infection. Cleaning your indoor cat's litter box routinely and preventing your outdoor cat from hunting can also help.
Young kittens should have routine fecal tests performed at 6-8 and 10-12 weeks of age. Regular fecal testing is an easy and effective way to detect coccidia and other intestinal parasites early and treat or prevent infection.
Your cat can be at risk of acquiring intestinal worms, including coccidia, at any time throughout the year. Many of the eggs released into the environment are very durable and can survive environmental extremes.
Are Painful?

Worms can be painful for cats, and in particular those with heavy parasite loads or related issues may become very unwell.
Cats with gastrointestinal symptoms such as vomiting, diarrhea and cramping can experience discomfort.
Worm larvae traveling through a cat's internal organs can cause inflammation of the affected tissues and further discomfort.
The discomfort can be severe enough to cause cats to become very unwell.
Preventing Parasites
Regularly cleaning and disinfecting your cat's litter box is a crucial step in preventing worms. This should be done daily to keep the environment clean and free of contamination.
Fleas carry worms, so a strict year-round flea prevention regimen can help reduce the risk of tapeworm infection. This is especially important for cats that spend time both indoors and outdoors.
Preventative deworming every 3 months can help eliminate any intestinal worms before they become a large burden for your pet. This is particularly recommended for cats that are avid hunters.

Diagnosing and Managing Parasites
Diagnosing parasites in cats is a straightforward process. Your veterinarian will ask you to bring in a stool sample, which will be examined under a microscope to determine the exact type of parasite infesting your cat.
A routine fecal test is an effective way to detect intestinal parasites early, and it's recommended to have your cat's poop examined annually for parasites. This is especially important for kittens, who are at high risk of roundworm infection.
To diagnose worms in cats, your veterinarian may also perform a physical exam, blood work, and examine the stool sample for visible signs of worms or eggs. This can be done at home by finding segments of tapeworms on the rear end of the cat, in the cat's poop, or where the cat lives and sleeps.
Here's a list of common symptoms of worms in cats:
- Visible presence: whole worms, parts of worms, or worm eggs in your pet's stool or vomit
- Change in coat: dull, rumpled, or clumped fur due to lack of nutrients or dehydration
- Change in color of gums: pale or white gums indicating anemia
- Vomiting: frequent vomiting, especially if accompanied by other symptoms
- Change in stool / bowel movements: dark, tarry stool or diarrhea
- Increased appetite despite weight loss: worms depriving your cat of vital nutrients
If you notice any of these symptoms, it's essential to have your cat examined by your vet immediately.
Diagnosing
Diagnosing parasites in cats can be a straightforward process, but it requires a bit of detective work. Your veterinarian will likely ask you to bring in a stool sample, which will be examined for parasite eggs or other signs of infection.
A fecal test is a common method used to diagnose worms in cats. The test involves placing a stool sample in a solution that allows the parasite eggs to separate from the feces and float to the top. This makes it easier to identify the type of worm infesting your cat.
Some worms, like tapeworms, can be seen by the naked eye. Your veterinarian may be able to diagnose tapeworms simply by examining your cat's stool or rear end for segments of the worm.
A microscopic examination of a stool sample can also reveal the presence of coccidia, a type of parasite that can cause diarrhea and other symptoms in cats. Coccidia eggs can be identified under a microscope, and a positive diagnosis can be made if the eggs are present.
Here are some common methods used to diagnose parasites in cats:
- Fecal test: a stool sample is examined for parasite eggs or other signs of infection
- Microscopic examination: a stool sample is examined under a microscope for parasite eggs or other signs of infection
- Physical exam: your veterinarian will perform a physical exam to look for signs of illness or infection
It's worth noting that some parasites can be difficult to diagnose, and multiple tests may be needed to confirm the presence of an infection. If you suspect that your cat has a parasite infection, it's always best to consult with your veterinarian for proper diagnosis and treatment.
Diagnosing and Managing Parasites
Diagnosing parasites in cats is crucial for their health and well-being.
A fecal test is a simple and effective way to detect parasites like coccidia in your cat's intestine. This test can be performed by your veterinarian and is usually done once or twice a year, even if your cat is not showing any clinical signs.
Young kittens are more susceptible to serious complications from parasites, so it's essential to have their fecal sample tested at 6-8 and 10-12 weeks of age.
Your veterinarian will use a broad-spectrum antiparasitic called Albendazole (Sulfadimethoxine) to treat coccidia in cats.
Deworming products can help kill every type of intestinal worm commonly found in cats, and your vet can help you determine how often worming treatments should be administered for your pet.
In many cases, dewormers may be given in multiple doses to interrupt the life cycle of the intestinal parasite, and it's essential to follow your vet's instructions for dosage amounts and when to administer them.
Gastrointestinal parasites are often easily treatable, and routine fecal testing can help prevent infection and detect parasites early.
When Should I?
When you're dealing with parasites in your cat, it's essential to know when to take action. You should start treating your kitten for roundworms at a young age, as they can be infected from their mother's milk.
Kittens are at high risk of roundworm infection, so it's best to deworm them at 6-8 and 10-12 weeks of age. This will help prevent any potential health issues.
If your kitten is hunting or eating wild animals, you should keep an eye on them to ensure they're not bringing parasites back home. Regularly removing poop from the litter box or outdoor area where your cat goes to the bathroom can also help prevent contamination.
Roundworms are extremely common in kittens, and they can be treated with deworming products. Your vet can help you determine how often worming treatments should be administered for your pet.
Here's a quick rundown of when to treat your cat for worms:
- Treating kittens for roundworms fortnightly from 3 weeks of age until 8 weeks of age, then monthly to 6 months of age
- Treating adult cats every 1-3 months depending on risk (influenced by hunting behaviour and outdoor access)
- Treating adult cats every 1-3 months with a product that is effective against both tapeworms and roundworms (depending on risk - influenced by hunting behaviour and outdoor access)
- Treating kittens that have fleas with a product active against Dipylidium caninum
Regular fecal tests can also help detect intestinal parasites early and prevent infection. It's essential to have your cat's poop examined annually, even if they're not showing any clinical signs.
Parasites from Animals
Cats can get tapeworms from infected fleas, which can be found on their fur or in their bedding. This usually happens when your cat grooms itself and accidentally swallows an infected flea.
Tapeworms are long, flat parasitic worms that attach themselves to your cat's intestines, recognizable by their multiple segments (proglottids).
Cats become infected by ingesting an intermediate host, usually another mammal infected with the tapeworm parasite. This can be a small rodent, rabbit, or even a large animal like a deer or sheep.
You can prevent tapeworm infestations in your cat and your home by administering a monthly flea preventative. This is one of the easiest ways to keep tapeworms out of your cat's stomach and your home.
Humans can also get worms from cats if they come in direct contact with infected feces or soil. This tends to happen when people are gardening without gloves or walking barefoot through infected soil.
The most common signs of human tapeworm infestation include visible eggs, larvae, or segments from the tapeworm in stools, abdominal pain, and vomiting.
