What are Hookworms?

Hookworms can cause anemia, small intestine inflammation, internal blood loss and bleeding at the site of the bite. Because of this, hookworms can be fatal if left untreated. Fatalities are most common in young kittens.

Ancylostoma hookworms are small, thread-like parasites that attach to the walls of the small intestine in cats, feeding on the blood of their host. Both Ancylostoma tubaeforme and Ancylostoma ceylanicum worms are known to invade cats. Hookworms are fairly common, infecting an estimated 10 to 60 percent of all cats at some point in their lives.

Symptoms of Hookworms in Cats

Symptoms are often mild in older cats and more pronounced in younger cats. These symptoms include:

  • Small lesions on the bottom of the foot pads and in-between toes
  • Pale mucous membranes in the lips, gums and nostrils
  • Poor coat
  • Diarrhea that may contain blood
  • Weight loss
  • Constipation
  • Black, tarry stools
  • Loss of appetite
  • Cough
  • Breathing difficulties
  • Wheezing

Causes of Hookworms in Cats

Hookworm eggs are passed through the stool where they hatch into larvae. Cats become infected with the larvae either through skin contact with an infected cat's stool in the dirt, sand or litter box, through the ingestion of other animals that are infected with hookworms, or by drinking water that is infested with the larvae. Kittens can become infected with hookworms by drinking their mother's milk. Once inside of the cat's body, the larvae migrate to the lungs and then into the small intestine. While in the small intestine, the larvae will attach themselves to the intestinal wall, feed on the cat's blood and mature into adult worms that can reproduce eggs that will then pass through the cat's stool. It takes approximately two to four weeks from the initial infestation for the cat to be able to pass on the hookworms to other cats, animals and humans. Outdoor cats, hunters, and cats in overcrowded shelters are most likely to become infected with hookworms.

Diagnosis of Hookworms in Cats

Because adult hookworms are typically 1/2-inch or less in size and produce small eggs and larvae, they are difficult to see in the stool with the naked eye. It's important to watch for the symptoms in cats in order to catch and treat hookworms before complications occur. 

The veterinarian will need to know the cat's complete health history, which will include a detailed list of the symptoms, an approximate date when the symptoms first began and if any other animals in the household have recently been diagnosed with hookworms. The veterinarian will suspect hookworms if other kittens in the litter have recently died. 

Hookworms are diagnosed by the veterinarian examining the cat's stool sample under a microscope. The stool specimen will be mixed with a solution that allows the eggs to float up to the top of the sample, making them easily visible under the microscope. Because hookworms typically reproduce daily, infestations are easily detected.

Cats who have been diagnosed with hookworms will have several labs drawn, which will include a complete blood count and a urinalysis. These labs will look for low hemoglobin levels that are indicative of anemia and low kidney function as a result of dehydration.

Treatment of Hookworms in Cats


A deworming medication will be prescribed to the cat. This medication will either expel the worms or kill them. Fenbendazole is a common ingredient in deworming medications and may cause vomiting. The medication will need to be given to the cat for three to five days to ensure that all of the hookworms have been expelled.

Pregnant cats should begin medication two weeks after breeding and continue until two to four weeks after giving birth in order to prevent the hookworms from being passed on to the kittens. Kittens should receive medication after they have reached three to four weeks of age and continue once a month to ensure that all of the hookworms have been expelled.


Cats who are severely anemic may need to receive iron and nutritional supplements until their iron levels are back to normal.

Fluid Therapy

If the cat is extremely dehydrated, hospitalization may be needed. Fluids will be given intravenously during hospitalization. The veterinarian will run frequent labs to ensure the cat's heart and kidneys are responding well to the fluid therapy.

Recovery of Hookworms in Cats

When caught early, the prognosis is good for cats who receive thorough treatment. The cat will need to follow up with the veterinarian as recommended to ensure that re-infestation does not occur. Though there is no vaccination available to prevent hookworms, there are medications available through prescription to prevent the parasite from infecting the cat. It's important to prevent future infestations by properly and frequently cleaning the cat's litter box and living area. Outdoor cats should be protected by paying close attention to areas where water gathers, such as small ponds, containers, and low-lying areas. 

Because hookworms can be passed to humans, it's important to take care when caring for the cat and cleaning its litter box by wearing gloves and with thorough hand washing.

Has Symptoms

Blood In Stool

My cat was diagnosed with hook worms & already took her 2nd (also last) dose a week ago today. Besides throwing up the next morning, she hasn’t had any issues & im very observant. Today I noticed she had blood in her fur & around her anus after going to the bathroom. There was a little in her stool as well but not as much as there was on the streaks up to her stomach. There wasn’t a lot of blood but it wasn’t that minimal either, she didn’t seem in pain while going to the bathroom. Unfortunately it’s the weekend & all the vets are closed unless I travel far to an emergency vet that may be costly just to find out it’s a side effect. Should I be worried? Help! Please.

Thank you for your email. If Bianca is eating and drinking well, and seems bright and happy otherwise, you shouldn't need to seek emergency care for her. She should have a recheck with your veterinarian to make sure that the hookworms are gone and determine why she is having blood around her anus, but if she is comfortable otherwise, you should be able to monitor her until Monday morning. If she becomes lethargic, inappetant, is vomiting or having more dramatic bleeding, you should make the trip to the emergency clinic. I hope that all goes well for her!

Thank you for your email. Unfortunately, without examining Nala, I'm not sure what she might have going on. It would be best to have her seen by a veterinarian. Many clinics offer a 'free first exam' that you may be able to take advantage of to have her seen and get an idea as to treatment and cost.

I found a stray cat and brought him home about a month ago. He has not shown any symptoms of being sick except he was super hungry. I figured it was Normal because he was out in the wild. He did not have worms in his poop but today he threw up and about a 3-4 inch worm was in his throw up. The worm was white in color. I was wondering if there is any medications to give him at the store because I can not afford to take him to vet at the moment thank you

There are various different worming products which may be purchased over the counter but the availability of the products would be dependent on your location and controls of medicines. Visit your local pet shop to look for products for kittens which are effective for tapeworm, hookworm and roundworm like praziquantel/pyrantel pamoate or similar (speak to the employees about which products they have available). Regards Dr Callum Turner DVM

Hi, my cat is about 12 months. Lately he always coughing. Sometimes when I play with him,I found white worm about 1-2cm in his butt. Did he infect with hookworm. If he really infected. Did Dr have any suggestions for his medicine. Thank you.

I have a 6 month old cat and recently was adopted by a stray kitten close to the same age. A stool sample for the stray showed hook and tape worms. The vet prescribed panacure for the hookworm and I forget the name of the tapeworm meds. My question is how long should I keep the stray isolated?

Two weeks after administration I would test the stray to see if there are any indications of parasites in the faeces, but I would also treat your other cat as well to be on the safe side; I would repeat the anthelmintic dose to be on the safe side and I would mix them afterwards. It is important to keep cats wormed on a regular basis to help prevent against future infections and clean the litter box immediately after each defecation to prevent reinfection. Regards Dr Callum Turner DVM

Thank you for the advice. The foul diarrhea from the stray was not getting better so the vet prescribed another 4 day dose of Panacure and now she believes he may also have Giardia. He has been put on Albon and after a few days the diarrhea was gone. Today was his last day of taking the Albon and the diarrhea has returned. His eating and drinking is fine so I'm at a loss of what it could be. Our new family member will be returning to the vet.
