Why do I need to worm my cat regularly?

Cats and kittens are most commonly affected by two types of worms: roundworms and tapeworms.

All kittens become infected with roundworms when they feed on their mother's milk.  Adult cats become infected mainly by grooming and hunting.

Roundworms can cause poor growth in kittens, and vomiting, diarrhoea, dull coat and lethargy in cats of all ages.

Cats become infected with tapeworms by swallowing fleas (which are infected with the intermediate life stage of the tapeworm) when grooming, and by hunting and eating raw meat.

Due to the potentially very serious health risks that worms pose to humans, especially young children and people with compromised immune systems, we recommend a comprehensive worming protocol.

Recommended worming protocols:


Kittens should be wormed every two weeks from two weeks of age until twelve weeks.  We recommend using Drontal all wormer tablets or Broadline.  From twelve weeks until six months of age we recommend monthly worming and then three to six monthly there after depending on lifestyle.

Adult Cats

The frequency of worming in adult cats is determined by their lifestyle and flea control regime. 

  • Cats that don't hunt or eat raw meat and are treated monthly for fleas with a good quality veterinary flea product that treats both fleas and roundworm (Revolution): 

These cats are considered low risk for tapeworm and should be wormed with a complete worming product twice a year. This can be achieved by giving your cat a Drontal worming tablet or applying Broadline.  

Broadline is a unique 'spot on' product which combines excellent flea control and a complete worming treatment in an easy to use topical preparation which is applied to the skin on the back of your cats neck. Broadline is effective against fleas for four weeks.  When Broadline has been applied there is no need to apply Revolution, Activyl or Bravecto for four weeks.  No more battling to administer worming tablets! We think that use of Broadline for worming is a no brainer!

  • Cats that hunt and or eat raw meat and cats who don't receive any regular treatment with a a combined flea and worm product:

These cats are considered high risk for tapeworm and as such they should be wormed every three months year round using either Broadline or Drontal worming tablets

It is important that you use a safe effective complete worming treatment.  Not all worming treatments are the same.  The best way to ensure you are using a good product is to buy it from a veterinary clinic versus a pet shop or supermarket. 

At Vetcall we only stock Drontal complete worming tablets as well as Broadline. 

The number of tablets or dose of Broadline required depends on your cat's weight.  If you are unsure of your cat's weight feel free to bring him/her down to the hospital for a free weight check.  We can even pop the tablet down or apply the treatment for you!
