Types of worm that can infest your cat

Worms are one of the most frequent illnesses that a kitten or cat may acquire. Worms can affect both cats and kittens. Cats may have worms at some point in their lives, and the severity of the infection varies from one cat to the next. It is necessary to do a worming examination on all kittens, regardless of whether they are adopted from a cattery or bought elsewhere.

If you observe any of the signs mentioned below, you should act quickly since your cat most likely need worming and the severity of the infestation may be life-threatening. Worming is usually entirely effective, particularly when combined with frequent stool tests, and your cat will recover to perfect health in a very short amount of time.

Worms may manifest themselves in a variety of ways. If you observe any of these symptoms, do not attempt to deworm your cat yourself unless you are unable to get your cat to a veterinarian. Certain worms are more hazardous than others, and a vet’s diagnosis is required in order to treat the patient properly.

Different types of worms need different approaches to treatment. The patent medications that are offered at your local pharmacy are usually targeted towards particular kinds of cats. As a result, the patent medication you select may be for a kind of cat that your cat is not and will thus be ineffective.

What are the indications and symptoms of a worm invasion?

Of course, a great deal is dependent on the severity of the infestation.

  • Your cat will usually seem sluggish, devoid of energy and enthusiasm. It is possible to look ill without really being sick. Because the worms are parasite that live off of the host’s body and physically eat it up, it is really very sick in a silent manner.
  • Your cat’s appetite will almost certainly be impacted; it may experience either a loss of hunger or a huge increase in appetite, leading to it stuffing itself.
  • You may notice that your stomach seems swollen, as if air has been pushed into it.
  • There may sometimes be diarrhea, as well as a watery and thin bowel movement; you may even detect blood in the stool at times.


Heartworms in dogs have gotten more attention than heartworms in cats, although they may be found in cats as well, albeit in a less common form. I’ve never heard of or seen a situation like this. Heartworms (also known as filariae) are transferred to cats by mosquitoes that have bitten a dog or cat that has been afflicted with the disease. Once restricted to forested and rural areas, the heartworm has now expanded to many parts of the United States, including the northeastern part of the country. The adult worm lodges in the heart and disrupts with the circulation of blood, resulting in breathing problems, weight loss, a cough, and even convulsions, depending on the situation

Intestinal Worms (Coccidia).

These are intestinal parasites that are persistent and cause symptoms that are similar to those of many other feline illnesses, particularly diarrhea, in their victims. They have the potential to deplete your cat’s strength nearly entirely and, as a result of the diarrhea, induce dehydration. NOTE: You may have heard of this parasite since Toxoplasma gondii, one of its strains, has lately received a great lot of attention. This strain has the potential to be infectious to pregnant women and to negatively impact the fetus. Despite the fact that Toxoplasmosis-related abnormalities are very uncommon, such women should be cautious to get their cat tested if they detect any signs of general ill health, including diarrhea, weight loss, coughing or other breathing problems, fever, and a lack of appetite in their cat. Keep your cat inside so that it does not come into contact with vermin, and do not give it raw meat. (In cats, stool and blood tests may be performed.)


Although uncommon in certain areas of the nation, these may also be caused by the consumption of raw fish or meat, as well as the ingestion of fleas and lice from infected mice and rats. They are difficult to eradicate because the head, which attaches itself to the intestinal wall and the worm itself may grow to be more than a foot in length, must be removed, and the worm itself can be more than a foot in length. It’s possible that there are multiple worms. When you observe what seem to be rice kernels surrounding the cat’s anus, it’s possible that you’re looking at a worm or worms. Even if they are tapeworm fragments, their existence does not always imply that the infection has been cleansed or eradicated. It is still necessary to remove the head itself, else the worms will stay.


Whipworms may be found in the cat’s colon and digestive system, but they are very uncommon (the cecum). Your cat will have the same symptoms as other kinds of worms, including diarrhea (both chronic and acute), blood loss, and severe intestinal irritation, which will make him feel uncomfortable and anxious.


Ascarids or roundworms are a kind of worm. Cats are particularly susceptible to these worms, which are the most prevalent kind. They are a white, slender worm that ranges in length from 1 to 4 inches in length. They develop in the gut and are detected in the feces of cats. They survive by ingesting nutrients from the digestive secretions of the domestic cat. They are often seen in kittens because the queen may transmit them to her litter via the blood of her offspring. A illness that is nearly entirely caused by the consumption of raw fish, this is emaciation. Infections with flukes are caused by parasitic worms that carry a virus-like organism that affects the lungs, liver, and small intestine of the cat. If the worms settle in the lungs, some of the problems are related to those of a respiratory disease, and if the worms settle in the intestines, some of the symptoms are identical to those of an intestinal infection.


Hookworms are blood-feeding parasites that may be especially deadly if they infest a kitten. They hook itself to the gastrointestinal tract of the cat, where they ingest the cat’s blood and energy as a result of the process. Ignoring the problem will result in diarrheal symptoms as well as weakness and weight loss, as well as severe anemia. Kittens are particularly vulnerable to anemia due to their small size.


This kind of worm affects the lungs and produces symptoms that are similar to those seen in respiratory illnesses such as asthma and allergies. Because you will not be able to see these worms in the feces, your cat’s cough and lack of thriftiness will be the most noticeable symptoms; other indications may include nasal discharge, fever, and lack of appetite. It is possible for a cat to get infected after consuming crayfish.


These parasites prey on the organ after which they were named. Although they are very uncommon, they may produce similar symptoms to those of the other kinds mentioned above.


  1. One of the most common errors cat owners make is attempting to worm their cats without expert assistance. All worming must be performed by a veterinarian or under the supervision of a veterinarian. You may only provide a patent medication to your cat if you are aware of the kind of worm that is involved.
  2. If no veterinarian is accessible and will not be available for an extended period of time, you may be forced to administer a patent medication. Follow the instructions to the letter, but don’t give up trying to locate a veterinarian.
  3. If you detect worms or suspect worms in your cat and are unable to take him to the veterinarian immediately away, feed him a bland diet consisting mostly of starch.  Avoid consuming large quantities of items that cause loose stools (such as raw meat, raw vegetables, or uncooked grains).
