Worms in cats

Tapeworms and roundworms are the most common intestinal parasites of cats.

Tapeworms are long flat worms composed of many individual segments which look like wriggling grains of rice in cat faeces.

Round worms are much shorter and rounder and produce microscopic eggs. Hookworm and whipworm are rarer but cause anæmia, loss of protein and gastrointestinal upsets.

Cats are infested with the flea tapeworm Dipylidium caninum by eating fleas carrying the tapeworm during grooming.  The tapeworm mature in cats and pass segments in the faeces which flea larvae ingest.

Cats are infested with the tapeworm Taenia taeniaformis when they eat infected rodents. Infestation with this worm is more common in hunting cats.

Roundworms, Toxocara cati and Toxascaris leonine, are common in young cats and kittens. Cats are infested with roundworm by ingesting worm eggs passed in cat faeces or by eating animals such as mice, which are infested with roundworm.

Most kittens are infested with Toxocara cati through their mother’s milk.

Toxocara cati can infest children if they ingest eggs attached to kitten hair or dirty litter trains.  The eggs hatch to larvae which migrate through the body and may cause damage. To prevent ingestion deworm kittens and cats as advised below, and dispose of litter and disinfect the tray with boiling water at least weekly.

Good quality broad spectrum wormers like Milbemax, Profender spot on and Drontal for cats are effective against all gastrointestinal worms.

Our recommended deworming protocol:

  • Kittens from 4 to 12 weeks of age
    • Treat every two weeks with Milbemax, Profender or Drontal for cats
  • Young cats 3-6 months
    • Treat monthly with Milbemax, Profender or Drontal for cats
  • Cats 6 months of age and older
    • Treat every three months with Milbemax, Profender or Drontal for cats

Hookworm

Hookworms attach to the intestinal wall with hook-like mouthparts. They are hard to see because they are only about 3 mm long and very thin.

Dogs are infested with hookworms in one of three ways:

1. Hookworm larvae pass from the dam to the pups through the placenta before birth

2. Pups ingest larvae in the mother’s milk

3. Larvae penetrate the skin

 

What problems do hookworms cause?

Hookworms suck blood from the tiny vessels in the intestinal wall and cause anaemia especially in puppies.  Pale gums, lethargy and weakness are signs of anaemia.

Hookworm also cause bloody diarrhoea, weight loss and failure to grow.

Hookworm larvae burrow into the skin and cause itching and discomfort in a heavily infested environment such as kennels.

 

How do we diagnose hookworm infestation?

Hookworms produce a lot of eggs which are easily found in faeces under a microscope. Faecal examination is less reliable in very young puppies.

 

How is hookworm treated?

Most broad spectrum wormers, like Milbemax and Drontal, kill adult hookworms. We repeat the treatment 2-4 weeks later to kill the next wave of larvae maturing into adult worms.

 

Are canine hookworms infectious to people?

Adult hookworms do not infect humans. However, hookworm larvae can burrow into human skin and cause itching. They do not mature into adults. Wear shoes to avoid skin contact with hookworm infested soil especially in wet weather.

 

How do we prevent hookworm infection?

1. Deworm pups at six weeks of age

2. Deworm pets at high risk of reinfestation

3. Pick up and dispose of dog faeces, especially in yards, playgrounds, and public parks.

4. Do not allow children to play in potentially contaminated environments.

5. Treat nursing bitches concurrently with their pups.

6. Use broad spectrum worm treatments that are effective against hookworms.
