Cats can have a variety of intestinal worms, including hookworms, roundworms, and tapeworms.
Hookworms are a common type of worm in cats, and they can cause anemia and weight loss.
Roundworms are another type of worm that can infect cats, often through contaminated feces or soil.
Tapeworms are typically acquired through eating infected prey, such as fleas or rodents.
Cats may not show obvious signs of worm infestation, but they can still cause significant health problems.
Some cats may exhibit symptoms like diarrhea, vomiting, or lethargy due to worm infestation.
If left untreated, intestinal worms can lead to serious health issues in cats, including malnutrition and even death.
Hookworms, for example, can cause anemia in cats, which can lead to pale gums and lethargy.

Types of Cat Worms
If you've ever seen a worm coming out of your cat's rectum, you know it can be a disturbing sight. A parasite was described as being round, whitish, and small, sticking to the cat's tail.
Some cat worms are quite small, like the one described in the comment section, which was only about half an inch long.
You might be wondering how to treat a cat worm infestation. A parasite was mentioned as lingering in the cat's tail, which suggests it may be difficult to remove.
Here are some common types of cat worms you should know about:
It's always a good idea to consult with a veterinarian if you suspect your cat has a worm infestation.
Identifying Worms in Cats
Cats with parasite infections can have a range of symptoms, from none at all to life-threatening ones.

Blood in feces is another symptom that may indicate a worm infection.
Vomiting is also a potential sign of worms in your cat.
If your cat is experiencing weight loss, it could be a sign of a worm infection.

- Weight loss
- Potbellied appearance
- Poor body condition and dull coat
- Skin problems

Common Cat Worm Issues
Cats with parasite infections might have no symptoms or serious ones. The symptoms of worms displayed by your cat will vary largely depending on what type of worm they have on board.
Some common signs of worms in cats include diarrhea or changes in fecal consistency, blood in feces, vomiting, loss of appetite, weight loss, and a potbellied appearance. Cats with a heavy worm burden may also have a potbelly but little fat cover over the spine or pelvis.
A potbelly in cats is a swollen tummy, round and full, often carried down low on the cat's body. It may even look like the cat is pregnant, but the rest of the cat's body is in poor condition.
Cats with intestinal worms may also experience vomiting or diarrhea due to the physical irritation of the stomach and intestinal lining. A very high worm burden can even obstruct the bowel and cause life-threatening vomiting.
Roundworms are the most common intestinal parasite to affect cats, followed by hookworms, whipworms, and tapeworms.
Here are some common signs of worms in cats:
- Diarrhea or changes in fecal consistency
- Blood in feces
- Vomiting
- Loss of appetite
- Weight loss
- Potbellied appearance
- Poor body condition and dull coat
- Skin problems
- Weakness/collapse
- Pale mucous membranes
- Dehydration
- Seeing worms in cat's feces or vomit
Photographs and Information
The photographs taken by nature and science photographer David Maitland reveal the tapeworms, roundworms, and other creepy parasites that live in cats, magnified up to 180 times.
These grim close-up images show the parasites that are more likely to reside in cats if they are not wormed regularly. Tapeworms can grow up to 16 feet inside dogs, roughly the height of a giraffe.
The photography project was created in collaboration with pet worming treatment brands Drontal and Dronspot, who worked to raise awareness about the importance of regular worming.

Photographer Captures Terrifying Parasite

Photographer David Maitland captured chilling images of tapeworms, roundworms, and other creepy parasites that live in cats. These parasites can cause a variety of illnesses in animals if not treated regularly.
Tapeworms can grow up to 16 feet inside dogs, roughly the height of a giraffe. They hook into the lining of a pet's bowels and develop long ribbon-like bodies.
Hookworms live in the digestive systems of pets and can infect humans by penetrating the skin, most likely through the feet. This can potentially cause serious damage to children's eyesight.
Eight in 10 cat owners don't know how often to worm their cats, according to research by Drontal and Dronspot.
Bladder
Bladder issues can be quite concerning for cat owners. Bladder worms are relatively rare in cats, but they can cause symptoms similar to a bladder infection.
Cats with a large worm burden may show signs of a classic urinary tract infection. They can be passed out during urination.
Bladder worms are identified as Pearsonema feliscati or Capillaria plica.
Specific Worm Types
Roundworms are the most common type of intestinal worm found in cats, and unfortunately, almost all cats are either born with them or acquire them soon after birth. They can grow up to 2 or 3 inches in length and resemble short strands of cooked spaghetti.
Two common species of roundworms found in cats are Toxocara cati and Toxacaris learning, which roam freely within the intestinal tract and eat food remnants. Roundworms can cause serious infections, such as ascariasis, which can lead to symptoms like poor growth, lethargy, and weight loss.
Here are some common symptoms of roundworm infection:
- Lethargy
- Gas
- Poor growth
- Bloated abdomen
- Loss of weight
- Diarrhea
- Vomiting
- No symptoms at all
Roundworm
Roundworms are the most common intestinal worms found in cats, and unfortunately, almost all cats are either born with them or acquire them soon after birth.
Toxocara cati and Toxacaris leonina are the two common species of roundworm found in cats, growing up to 2 or 3 inches in length and resembling short strands of cooked spaghetti.
These worms roam freely within the intestinal tract, eating food remnants rather than attaching themselves to the intestinal lining to feed on blood.
Transmission of roundworms happens most often when a cat ingests worm eggs or larvae that are passed through the waste of infected animals or found in the cat's prey, such as birds, rats, and roaches.
Dormant roundworm larvae can activate after several years and grow into adults, and pregnant cats can pass the parasites to their unborn kittens or later through nursing.
Symptoms of roundworm infection in kittens include poor development, stunted growth, lethargy, excessive gas, weight loss, diarrhea, vomiting, and a pot belly.
Here are some common symptoms of roundworm infection:
- Lethargy
- Gas
- Poor growth
- Bloated abdomen
- Loss of weight
- Diarrhea
- Vomiting
- No symptoms at all
Hookworm
Hookworms are a common problem for cats, especially kittens. They can grow up to one-half to one inch in length and are typically white or pale yellow.
These parasites can be contracted through contact with infected animals or their waste, or even by eating contaminated food or soil. Kittens can also get hookworms from their mothers through the uterus or milk.
Hookworms can cause skin irritation and secondary infections, as well as anemia due to feeding on blood in the small intestines. Some cats may not show any symptoms at all.
If your cat does have hookworms, you might notice skin infections, weight loss, a poor coat, or bloody stool. Diarrhea with blood is also a possible symptom.
Here are some common symptoms of hookworm infection in cats:
- Skin infection
- Loss of weight
- Poor coat
- Bloody stool
- Diarrhea, which may also contain blood
- Anemia
Tapeworms
Tapeworms are a common issue in cats, and it's essential to know how to identify and prevent them. Tapeworms typically reside in the small intestines and attach themselves to the interior wall.
They grow in small segments that chain together and look like grains of rice when they break away from the larger chain. These segments may contain tapeworm eggs and can be shed out of the cat's butt.
Cats usually acquire tapeworms by eating the intermediate host, such as a flea or small mammal. This is why flea prevention is crucial in preventing the spread of Dipylidium tapeworms.
Kittens are more susceptible to symptoms of tapeworm infection, which can include stunted growth, digestive upset, and intestinal blockage. Adult cats may not show any symptoms at all.
Some common symptoms of tapeworms include loss of weight, poor growth, poor coat, bloating, digestive upset, diarrhea, and vomiting. Worm segments may also be seen around an infected cat's rectum or in its waste.
Here are some common symptoms of tapeworms in cats:
- Loss of weight
- Poor growth
- Poor coat
- Bloating
- Digestive upset
- Diarrhea
- Vomiting, which may include worm segments
