Hookworms in Cats: Symptoms, Treatment and Human Risk

In this guide

Hookworms are small intestinal parasites that attach to the gut wall and feed on blood, and while less commonly discussed than fleas or roundworms, they are a real concern for outdoor cats, street cat colonies, and kittens in India, where warm soil provides ideal conditions for hookworm larvae to survive and infect a new host.

How cats get infected

• Ingesting larvae from contaminated soil or while grooming
• Larvae penetrating directly through the skin, particularly the paws
• Kittens becoming infected through their mother's milk
• Eating an infected rodent or other small prey

Signs of infection

• Dark, tarry stools, a sign of blood loss in the gut
• Pale gums from anaemia, especially serious and sometimes fatal in kittens with a heavy worm burden
• Weight loss and a poor coat
• Lethargy and weakness
• Diarrhoea, occasionally with visible blood

Diagnosis and treatment

A simple faecal flotation test under the microscope identifies hookworm eggs and is a routine part of a wellness check for outdoor and community cats. Treatment uses standard deworming medications such as pyrantel or fenbendazole, usually given as an initial dose followed by a repeat two to three weeks later to catch larvae that were not yet mature enough to be killed the first time. Kittens with significant anaemia may need additional supportive care, including iron supplementation or, in severe cases, a blood transfusion.

The human health angle

Hookworms are zoonotic. Humans cannot become infected with adult intestinal worms the way cats do, but hookworm larvae can penetrate human skin, most often through bare feet or hands in contact with contaminated soil or sand, causing an itchy, winding rash called cutaneous larva migrans. This is a real risk in India given how many outdoor and community cats carry the parasite, which is one more good reason to wear footwear in gardens and outdoor play areas and to deworm outdoor cats regularly.

Prevention

• Deworm kittens starting from two to three weeks of age, then on a regular schedule as advised by your vet
• Deworm outdoor and community cats every three months, or as your vet recommends based on exposure risk
• Clean up faeces from gardens and outdoor spaces promptly rather than letting it sit in soil
• Keep flea control current too, since fleas and hookworms often show up together in the same untreated cats
