Types of Worms in Cats

Cats can get hit with all sorts of worms, and each brings its bag of troubles. Knowing what it is like having a secret weapon against catworm chaos. Check out these wormy troublemakers:

1. Tapeworm

Tapeworms are intestinal parasites that are typically acquired through the absorption of infected fleas while grooming.

Scooting, little rice-like fragments around the anus or in feces, weight loss, and fatigue are all possible symptoms. If you suspect your cat has tapeworms, see your veterinarian for a complete diagnosis and treatment. Regular veterinary check-ups and preventive treatments are vital for keeping your cat healthy.

2. Roundworms

Roundworms may be observed in the cat’s vomit or feces, resembling spaghetti. A distended or swollen belly, particularly in kittens, could indicate a substantial infestation of worms.

3. Hookworm

Hookworms are small parasites that live in a cat’s small intestine and feed on its blood. Cats can get them from polluted settings or when lactating. The symptoms include diarrhea, weight loss, and anemia.

A veterinarian does a fecal examination to determine the diagnosis. Treatment with deworming drugs is critical. Maintaining a clean environment and scheduling frequent veterinary check-ups are both preventative measures.

4. Heartworm

While heartworm is typically associated with dogs, cats can also become infected by this parasite transmitted by mosquitoes. However, in cats the immature worms don’t reach adulthood but can still wreak havoc as they migrate, causing respiratory issues like coughing and wheezing.

In severe cases, the larvae can lead to fluid buildup around the lungs and heart failure. Diagnosis requires special blood tests. Unfortunately, there’s no approved treatment to eliminate the immature worms from cats.

Prevention through year-round monthly medication is critical, especially for outdoor cats or those in mosquito-heavy areas, though indoor exposure is still possible. Vets strongly recommend keeping all cats on preventatives to avoid this dangerous parasite.

5. Stomach Worms

Stomach worms are among the most prevalent intestinal parasites in cats. The scientific name is Toxocara cati. Kittens can become infected through their mother’s milk, whereas adult cats can contract the disease by eating rats or other small animals that contain roundworm larvae.

6. Bladder Worms 

Bladder worms affect a cat’s urinary tract when ingesting contaminated water or soil. Diagnosis involves veterinary tests like urine analysis, imaging, or cystoscopy.

Treatment includes prescribed deworming medications, and in severe cases, supportive care such as fluids and pain management may be necessary. Preventive measures include regular deworming and also minimizing exposure to contaminated environments, and providing clean water.

7. lungworm

A widespread parasite resides in the bronchi and alveoli of infected cats’ lungs. Infected cats often exhibit minimal or no symptoms, making the infection asymptomatic. Unfortunately, this lack of apparent signs can contribute to shorter lifespans in cats affected by the parasite.

8. Whipworms

Whipworms are intestinal parasites that affect cats. Infection occurs through ingesting whipworm eggs found in contaminated soil or feces. Symptoms include chronic diarrhea with mucus or blood, weight loss, or potential dehydration. Veterinary diagnosis involves fecal testing and treatment with possible supportive care for severe cases.

How do cats get worms?

Cats can acquire worms through various means, including:

  1. Ingestion of Infected Prey: Cats may contract worms by hunting and consuming infected rodents, birds, or other small animals.
  2. Contaminated Environment: Worm eggs or larvae present in contaminated soil, water, or feces can be ingested by cats, leading to worm infestation.
  3. Mother to Offspring Transmission: Kittens can inherit worms from their mother through infected milk or during the birthing process.
  4. Fleas and Parasites: Cats can get worms from ingesting fleas or other parasites that carry worm larvae.
  5. Eating Infected Feces: Cats may get worms by coming into contact with and ingesting the feces of infected animals, either directly or indirectly.

Regular veterinary check-ups, proper hygiene, and preventive measures such as deworming can help reduce the risk of worm infestations in cats.
