Kitten Worming Schedule

Last Updated on March 22, 2021 by Julia Wilson

Why do kittens need to be wormed?

Kittens become infected with hookworms and roundworms via their mother when they are young kittens. Fleas spread tapeworm, even indoor cats can become infected.

Worms are more than a nuisance, they can cause gastrointestinal obstruction, anemia and malnutrition, especially in young kittens.

Kitten worming schedule

  • Every 2 weeks from 2 weeks of age until 12 weeks of age.
  • Every month from 12 weeks of age until 6 months.
  • Every three months from 6 months.

The above schedule is a guide, once your cat has reached three months, the timing between dosages can vary depending on the brand you are using. For example, if you are combining flea control with worming (such as Revolution), the schedule will be once a month. Always follow the directions on the packaging and never administer a flea or worming treatment for dogs to cats.

Not all products treat all parasites. Always check that the product you are using is also a heartworm preventative. If it is not, it will be necessary to use a second treatment to prevent heartworm. 

Treat all cats for the following parasites:

  • Fleas
  • Heartworm preventative
  • Tapeworm
  • Roundworm
  • Hookworm
