Feline Worms --Hookworms

Hookworms are blood sucking parasites of the small intestine that cats can become infected with in a number of ways.

A common cause of infestation in cats is through the eating of contaminated grass or other vegetation, the eating of soil or the drinking of water that is contaminated with the hookworm larvae.

A cat can also become infested with hookworms by hunting and eating infested wildlife. Larvae boring through the cat’s skin is another way that your cat could become infested.

From the above it can be seen the cats that are allowed to roam outside are more at risk of hookworm than cats that are indoor only.

Indoor cats are not entirely free from risk however.

The kittens of an infested mother can be born with the worms; it is also believed by some that an infested mother cat can pass the worms through her milk.

It is possible for humans to be infested with hookworm larvae. People who walk barefooted are most at risk because it is the feet and legs that the larvae most often attacks.

The larvae will burrow itself into the skin causing a itchy red abrasion, which usually clears in a few weeks when the larvae die.

An infestation in a small child can be more severe however.

The treatment of these cat worms is usually fairly simple; usually two treatments of deworming medication will eradicate the worms.

You will want to take your cat to the vet in cases of heavy infestation. In extreme cases cats suffering from anemia caused by hookworms may require a blood transfusion.

Your pet can pick up these round cat worms by eating prey that is infested with them. Eating grass or other vegetation, or just by contact with the eggs of the roundworm.

Kittens can receive the Toxocara cati worm from their mother’s milk and for this reason it is assumed that it is likely a kitten will be infected with this worm.

How is roundworm in cats treated?

As roundworm is so common in kittens your veterinarian will likely administer deworming medication during the kittens vaccination visit.

Roundworm treatment for cats and kittens only kills the adult worm, the larvae survive. Several treatments are needed.

Usually an infestation of roundworm is not acutely dangerous for a cat, (but should be treated.) A severe infestation however can cause a blocked intestine or pneumonia; treatment of a severe infestation is therefore vital.

Roundworms compete with your cat or kitten for food, which could result in lack of nourishment for your pet.


It used to be thought that instances of feline heartworm are rare. Today it is realized that although felines stand less of a chance of infection than dogs, if a cat does get infected, it is usually more devastating.

This is because there is no approved treatment for cats as of yet.

Just a few adult worms can severely cripple a cat because of their small heart size. Feline Heartworm
