Why do I need to worm my cat regularly?

17 Oct 2018

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 complete worming and flea treatment in an easy to use topical preparation which is applied to the skin on the back of your cats neck. In our experience Broadline is effective against fleas for about three to four weeks. When Broadline has been applied there is no need to apply Revolution, Activyl or Bravecto for three to four weeks.  No more battling to administer worming tablets! 

  • 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 and complete worming treatment.  Not all worming products are the same and often those stocked in supermarkets and pet stores are ineffective and or not a complete wormer.  To ensure you are using the best product for your cat, have a chat with one of our team about your cat's lifestyle and flea control program, and we will make a recommendation that will best suit you and your cat.

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!
