What will happen if you don’t deworm a cat?

Failure to take preventive measures or administer deworming treatments to your cat can have severe consequences, potentially leading to their demise. This concern is particularly critical for kittens, as their weaker immune systems make it more challenging for them to combat worm infestations. The parasites of primary concern are usually roundworms and hookworms, both of which are intestinal parasites. These worms reside in the intestines and can cause a range of health issues for your cat, including vomiting, diarrhea, and loss of appetite.

The presence of worms interferes with the cat’s ability to absorb vital nutrients and stay adequately hydrated, compromising their overall health. Furthermore, these parasites can cause blood loss, potentially leading to anemia. If left untreated for an extended period, the anemia can become severe, leaving your cat too weak to recover. In some cases, the infestation can even lead to a prolapse, further worsening the cat’s condition.

To ensure the well-being of your feline companion, it is crucial to implement preventive measures and promptly administer deworming treatments as recommended by your veterinarian. Regular deworming helps protect your cat from the harmful effects of these parasites, preserving their overall health and vitality.

What types of worms are most common in cats?

  • Roundworms (Toxocara cati and Toxascaris leonina): Roundworms are the most prevalent intestinal parasites in cats. They are long, cylindrical worms that live in the small intestine. Kittens can become infected with roundworms through their mother’s milk, while adult cats can acquire them by ingesting contaminated soil, water, or prey. Symptoms of roundworm infestation include a potbellied appearance, poor growth, vomiting, diarrhea, and a dull coat.
  • Tapeworms (Dipylidium caninum and Taenia species): Tapeworms are flat, segmented worms that live in the intestines. Cats can become infected by ingesting fleas or rodents that are carrying tapeworm larvae. The presence of tapeworms is often indicated by the appearance of small white rice-like segments in the cat’s feces or around the anal area. Affected cats may also experience weight loss, irritability, and itching around the anus.
  • Hookworms (Ancylostoma species and Uncinaria stenocephala): Hookworms are small, thread-like worms that attach to the intestinal wall and feed on blood. Cats can acquire hookworms through ingestion, skin penetration, or from their mother’s milk. Symptoms of hookworm infestation include anemia, poor appetite, weight loss, diarrhea (which may be bloody), and weakness. Hookworm larvae can also penetrate the skin, causing skin lesions and inflammation.
  • Whipworms (Trichuris vulpis): Although less common in cats compared to dogs, whipworms can still affect felines. These worms inhabit the large intestine and can cause chronic diarrhea, weight loss, and overall poor condition. Infections usually occur through ingestion of contaminated soil or feces.

What are the symptoms of a cat infected with worms?

Cats infected with worms can exhibit a range of symptoms, although some infected cats may not show any signs at all. The symptoms can vary depending on the type of worms and the severity of the infestation. Here are common symptoms that may indicate a cat is infected with worms:

Vomiting: Worm infestations, especially heavy ones, can irritate the cat’s digestive system, leading to vomiting.

Diarrhea or bloody stool: Worms in the intestinal tract can cause diarrhea, which may sometimes contain blood or mucus.

Weight loss: Worms compete with the cat for nutrients, leading to malnutrition and weight loss despite a normal or increased appetite.

Poor coat condition: A cat with worms may have a dull, dry, or scruffy coat due to nutrient deficiencies and overall poor health.

Potbellied appearance: In some cases, particularly with roundworms, an infested cat may develop a swollen or potbellied abdomen.

Anemia: Certain types of worms, such as hookworms, can cause blood loss, leading to anemia. An anemic cat may appear weak, lethargic, or have pale gums.

Increased appetite: Some cats infected with worms may experience an increased appetite as their body tries to compensate for nutrient loss.

Lethargy and weakness: Cats with worm infestations may appear lethargic, have reduced energy levels, and exhibit general weakness.

Visible worms or segments: In the case of tapeworms, small white rice-like segments may be visible in the cat’s feces or around the anal area.

Itching and irritation: External parasites, such as fleas or mites that transmit certain types of worms, can cause skin irritation, itching, or excessive grooming.
