Worming Your Cat

Worming your pet every month or 3 months is essential to maintain your pet’s health and eliminate public health dangers.

We are worming against three main types of worms:

Cats become infected with Aelurostrongylus abstrusus by ingesting intermediate hosts such as snails or paratenic (paratenic describes an intermediate host which is not needed for the development of the parasite, but nonetheless serves to maintain the life cycle of the parasite) hosts (birds, rodents etc).

After ingestion, the larvae pass into the intestine. The larvae penetrate intestine wall and migrate to the lungs in the blood, once they have matured to adult worms (approx 40 days) they lay eggs, these hatch into microscopic larvae which are coughed up, swallowed & passed in the faeces.

These can be transferred to your cat in three ways:

  • In the womb
  • Via the mother’s milk
  • Contact with eggs in the environment

Signs of a roundworm infestation include weight loss, anaemia and vomiting. In extreme cases death, due to heart failure, may occur.

These are transferred to your cat when an infected flea or louse is swallowed; therefore regular flea control is also necessary. The tapeworm can also infect your pet if a contaminated bird or rodent is eaten.

A tapeworm infestation can cause vomiting and diahorrea.

Tapeworm segments are usually visible around the anus or passed in faeces.


On collection of your kitten, check with the breeder if they have administered any worming or flea preparations prior to you taking the kitten home. This enables us to be sure when your next worming dose is due.

We recommend using a monthly spot-on product (imidacloprid and moxidectin*), which can be applied from 9 weeks of age in kittens. You will receive a free dose at your pet’s first vaccination. This will treat your pet for one month against:

  • Roundworms
  • Fleas
  • Ear mites

Monthly spot-on worming (imidacloprid and moxidectin*) should continue monthly until your pet is six months old.

Cats from 6 months

For pets using a monthly spot-on (imidacloprid and moxidectin*), we recommend a tapeworm product at 6 months of age. This should be repeated every 6 months.

For pets on other flea control products we recommend a tapeworm every 3 months.

Recommended Tapeworm products:

  • Drontal Cat tablet
  • Spot-on (emodepside and praziquantel*****) for cats
