Worms In Cats! Are They Deadly?

What Are The Symptoms Of Worms In Cats?

The Symptoms of worms in a cat range from entirely asymptomatic to severe and life-threatening. It depends on the type of worm and the severity of the infection. 

Some of the most common signs of worms in cats include: –

  • Weight Loss
  • Tarry Poop
  • Diarrhea
  • Difficulty in breathing
  • Wheezing
  • Dull coat
  • Weakness
  • Dehydration
  • Low blood pressure
  • Pale lips and gums

5 Types Of Worms And Their Symptoms

Now let us dive into more specific types of worms and the symptoms they cause.

5 Types Of Worms And Their Symptoms

1. Roundworms

The most prevalent intestinal parasite in cats is intestinal roundworms, which can be found in cats of all ages worldwide. Toxocara cati and Toxascaris leonina are the two most frequent roundworms found in cats.

These worms’ eggs are excreted in the feces and can survive for several years in the environment. These eggs have two means of infecting other cats. First, a polluted environment may cause a cat to eat (ingest) eggs.

Second, if another animal consumes the eggs (for example, a mouse or rat), the illness can be passed on to a cat if it preys on (and eats) the infected intermediary host.

Toxocara cati is also handed on through the mother cat’s milk to her offspring. When a cat is infected with roundworms, some juvenile forms (larvae) can be found hibernating in the body’s tissues.

When a female cat becomes pregnant, the larvae migrate to the mammary glands and are expelled in the milk she provides for the kittens. Because this is such a prevalent mode of infection, we should expect every kitten to be infected with Toxocara cati.

In most circumstances, roundworm treatment should be done regularly throughout a cat’s life.


  • Diarrhea
  • Distended abdomen
  • Weight loss
  • Coughing
  • Pneumonia
  • Vomiting
  • Intestinal Obstruction

2. Hookworms

Hookworms are a form of tiny intestine roundworm that can be found in almost every country, but they are more frequent in some than others.

When these worms stick to the intestine’s surface, they can cause damage to the lining, resulting in weight loss, bleeding, and anemia.

Cats can become infected by ingesting (eating) eggs from the environment, eating an infected intermediate host (as in the case of Toxocara cati), or by larvae burrowing through the cat’s skin.

Ancylostoma tubaeforme and Uncinaria stenocephala are the most common cat hookworms, but other species are seen in different areas.


  • Skin lesions
  • Coughing
  • Lack of appetite
  • Pale lips and gums
  • Weight Loss
  • A dark or tarry stool
  • Diahrrea

3. Tapeworms

Tapeworms are long, flat worms with a large number of segments. The tapeworm’s mature segments, which contain eggs, are discharged and passed in the feces.

These segments, which resemble rice grains, can be found in the cat’s hair near the anus, in the feces, and on the cat’s bed.

All tapeworms require an intermediate host to complete their life cycle. The intermediate host must first ingest the eggs from the environment, and then the cat must eat the intermediate host to become infected.

Depending on the tapeworm type, different animals serve as intermediary hosts. Dipylidium caninum and Taenia taeniaeformis are the most frequent tapeworms found in cats around the world.

Cats get infected with Dipylidium caninum, which is spread by fleas. Immature flea larvae consume the worm’s eggs, but illness is passed on to a cat when it eats an infected flea during grooming.

It should be assumed that any cat infected with fleas also has Dipylidium caninum and vice versa.

When they eat small rodents (rats and mice), Taenia taeniaeformis is passed on, with the rodents having eaten eggs from the environment. This illness is pretty frequent in hunting cats.


  • Worm segments present on and around the anus
  • Worm segments around the anal area and under the tail, attached to the fur
  • Worm segments present in or on the poop of the cat

4. Whipworms

Whipworms, also known as Trichuris Serrata, are named because they are shaped like a small, 45-75mm whip.

Whipworm infections are more common in dogs than in cats, although cats and kittens should still be treated cautiously.

Ingesting anything contaminated with whipworm eggs or larva can cause infection in cats. Whipworms can live anywhere from a few months to a few years in soil, food, and water. Their eggs could be discovered in feces and animal flesh.

The eggs are swallowed and go to the cat’s intestine, where they hatch after three months. Whipworms take on nutrients from your cat’s already digested food in the soft tissue.

Your cat’s immune system will quickly deteriorate, and its bowels will become irritated. Your cat will begin to lose weight, get listless, and become unwell as the whipworm absorbs so much of its nutrients.


  • Large bowel diarrhea accompanied by blood
  • Dehydration
  • Anemia
  • Weight Loss

5. Lungworm

Lungworm infection in the lower respiratory tract can be caused by various parasitic nematodes (roundworms), including Aelurostrongylus abstrusus and Eucoleus aerophilous in cats resulting in bronchitis or pneumonia.

Aelurostrongylus abstrusus is usually transmitted to cats through the consumption of a bird or rat that has eaten a slug or snail harboring the worms.

In cats, Eucoleus aerophilous has a natural cycle in which infective eggs are ingested with food or water.

Lungworm infections can be challenging to cure, but there is evidence that using the proper antiparasitic medication can help. Antiparasitic therapy may be required for up to two months.


  • Coughing
  • Pneumonia as the infestation worsens and symptoms progress
  • Difficulty in breathing
