The species involved
The feline hookworm is Ancylostoma tubaeforme. Cats can also carry Ancylostoma braziliense and the northern hookworm Uncinaria stenocephala.
How cats get infected
- Swallowing larvae from soil, prey or while grooming
- Larvae penetrating the skin
- Hunting and eating infected rodents (a common route for outdoor cats)
Signs to watch for
Weight loss, a poor coat, pale gums and dark stool. Cats are fastidious groomers, so owners often notice subtle condition changes before obvious gut signs. Kittens are most vulnerable to anemia.
Treatment & control
Fenbendazole (used off-label in cats under veterinary guidance) and pyrantel are effective; several monthly feline preventives also cover hookworms. Repeat dosing and a clean litter and outdoor area prevent reinfection.
*Fenbendazole is used off-label in cats under veterinary direction.
Confirm with your vet. Species, age and weight all change the right product and dose. Use this guide to understand the problem, then let your veterinarian tailor the plan.
