Understanding De-worming Regimes for Pregnant Queens and Newborn Kittens

Pregnant Queens

It is best to deworm your female cat prior to breeding. However, if the queen becomes pregnant unexpectedly, she can be treated with a fenbendazole wormer. You should not use any other wormer types unless it is recommended or prescribed by your vet.

Do not forget to regularly treat your queen for fleas pre- and post-pregnancy, as the flea is the intermediate host of the common tapeworm (Dipylidium). In addition, if there are fleas in the environment, they can cause life-threatening anaemia in the new born kittens. Not all flea products are safe to use during pregnancy, however, so make sure you check with your vet which product they recommend.

Not all products are suitable for use in pregnancy; always consult your veterinary surgeon for advice regarding suitable products to use during the pregnancy.

Worming kittens

In young kittens worming is essential from 2 weeks of age as the kittens can ingest worm larvae in the mother’s milk. Wormers are available for kittens (containing fenbendazole) covering the following worms:

  • Tapeworms (Taenia sp)
  • Roundworms (Toxocara cati)
  • Hookworms (Ancylostoma sp)
  • Giardia infections (Giardia sp)

Kittens should be wormed every two weeks from 2 weeks of age until 12 weeks of age, and then every month until the kitten is 6 months of age when they can be treated as adults (de-wormed every 3 months).
