How To Know If Cat Has Parasites

Cats with parasites may exhibit a variety of symptoms and these can include a dull coat, coughing, vomiting, diarrhea, mucousy or bloody feces, loss of appetite, pale mucous membranes, or a potbellied appearance.

Other signs of parasites in cats can include vomiting (sometimes with worms in the vomit), diarrhea (with or without blood), tarry feces, weight loss, distended abdomen, skin lesions, and generally poor body condition and a dull coat.

Additionally, cats with parasites may experience weakness, dehydration, pale lips and gums due to anemia, low blood pressure, shock, and even death in severe cases.

If you suspect your cat has parasites, it is important to take them to a veterinarian for diagnosis and treatment.

Types of cat parasites

There are several types of parasites that can affect cats, including:

  1. Roundworms: such as Toxocara cati and Toxascaris leonina.
  2. Hookworms: such as Ancylostoma tubaeforme and Ancylostoma braziliense.
  3. Tapeworms: such as Dipylidium caninum and Taenia taeniaeformis.
  4. Heartworms: such as Dirofilaria immitis.
  5. Fleas: These can cause flea allergy dermatitis and transmit diseases such as bartonellosis.
  6. Ticks: These can transmit diseases such as Lyme disease and anaplasmosis.
  7. Ear mites: These can cause inflammation and infection of the ear canal.
  8. Intestinal protozoa: such as Giardia and coccidia.

Signs and symptoms of cat parasites

Here are some common signs and symptoms of cat parasites:

1. Itching and Scratching

Common external parasites like fleas and mites can make cats extremely itchy.

While mites are microscopic parasites that burrow into your cat’s skin, fleas are small, wingless insects that feed on the blood of your cat.

The frequent scratching can cause skin infections, scabs, and hair loss, these are clear signs of parasites in cats.

Fleas can also result in flea allergy dermatitis, an allergic response to the saliva of the flea.

2. Persistent Diarrhea

In cats, diarrhea is a typical symptom of several different parasites kinds.

Diarrhea can be brought on by parasites such as roundworms, hookworms, and coccidia that harm the lining of the intestines.

Dehydration and electrolyte imbalances brought on by diarrhea can be fatal if left untreated.

3. Visible Parasites

In a cat’s feces or vomit, several parasites can be found, including roundworms and tapeworms.

While tapeworms may resemble little grains of rice, roundworms may resemble spaghetti.

It’s crucial to take your cat to the clinic for treatment if you find these worms in their feces or vomit.

If you see fleas or ticks on your cat, it’s important to remove them promptly to prevent further infestation.

4. Poor coat condition

External parasites like fleas and mites can give cats’ coats a dull or unkempt appearance.

Small, wingless insects known as fleas live exclusively on the blood of cats.

They might make you itch and scratch, which might harm your coat.

Small arachnids called mites can penetrate a cat’s skin and cause baldness, scabs, and skin irritation.

5. Persistent weight loss

Cats can lose weight as a result of a particular form of parasite called tapeworms.

These worms, which can reach lengths of several feet, are found in the intestines of cats.

When tapeworm eggs are consumed by a cat, the eggs may hatch, and the larvae may cling to the intestinal lining.

Despite having a healthy appetite, the worms deplete the cat’s nutrients, which results in weight loss.

6. Persistent Vomiting

Cats who have roundworms, a common form of the parasite, may vomit persistently.

These worms, which can reach lengths of several inches, are found in cats’ intestines.

Roundworm larvae can spread to many sections of the body after being consumed by cats, which might result in vomiting.

The vomit caused by these parasites in cats could be frothy or have worms in it.

7. Lethargy

Cats who have parasites may feel weak and exhausted. They can be less active and sleep more than normal.

This is due to anemia, a disease in which there are not enough red blood cells to deliver oxygen throughout the body, which is brought on by the parasites eating away at the cat’s food supply.

8. Changes in appetite

Cats’ appetites can also be impacted by parasites.

While some cats may suffer from decreased appetite and lose interest in food, others may feel more hungry and overeat.

If left unaddressed, these fluctuations in appetite might result in weight loss or gain, respectively, and other health issues.

9. Respiratory Issues

A cat’s respiratory system can become infected by parasites, which can cause coughing, wheezing, or other respiratory symptoms.

For instance, lungworms are a particular kind of parasite that affects the lungs and respiratory system, resulting in coughing, breathing difficulties, and other respiratory symptoms.

Diagnosis of cat parasites

To diagnose cat parasites, a veterinarian can examine the blood, feces, or urine of the cat.

Diagnosis is confirmed by finding parasite eggs in the stool during a microscopic examination.

A veterinarian can perform these diagnostic tests and identify the specific type of parasite that is affecting the cat.

Treatment of cat parasites

The treatment of cat parasites depends on the type of parasites present.

Some common types of parasites that infect cats include roundworms, tapeworms, hookworms, and heartworms.

Treatment often involves medication prescribed by a veterinarian.

The specific medication used will depend on the type of parasite present.

For example, dewormers are typically used to treat intestinal parasites such as roundworms and tapeworms.

Other medications may be used to treat heartworms, although it can take a few days for a worm to leave cats after medications.

It’s important to follow the treatment regimen prescribed by your veterinarian and to provide follow-up care as needed to ensure that the parasites are completely eradicated.

Additionally, preventing parasites is important for the health of your cat.
