Fleas and worms

Why should I treat my cat for parasites?

Fleas, ticks, worms and other parasites should be prevented as they feed on your pet’s skin or gut, causing ill health.

Regular worming, and careful litter cleaning, are also important to prevent people getting toxoplasma.

Which skin parasites should I treat my cat for?


Fleas may be picked up from other animals, or from the environment. Fleas bite your pet causing sore skin, feed on your pets blood causing anaemia, and when your pet grooms and ingests fleas, this transmits tapeworms. You may not see the fleas as they hide quickly in the coat, so it is best to check by brushing the coat onto wet paper and looking for red flea dirt. If you do get a flea infestation, regular treatment of all pets and the house is needed to clear it- 90% of the fleas will be in the home ready to infest your pet.


Ear mites and mange mites can be passed between cats, dogs and foxes and are very contagious. Ear mites cause a painful, inflamed ear, whilst mange mites burrow under the skin causing sores and infection.

Which product should I treat my cat with for skin parasites?

We advise monthly Endectrid spot-on, providing protection against fleas, ear mites, and mange mites. Prevention is better and easier than cure, so it is important to ensure that your pet is treated monthly.

Which worms should I treat my cat for?


All kittens can be born with roundworms as they can be transmitted in their mother’s milk. Roundworms are picked up from the environment where their eggs can survive in soil for a long time. They can also be caught from eating infested rats or birds. Roundworms look like spaghetti and live in the gut.


Tapeworms are easily picked up by scavenging carcasses, hunting, or ingesting fleas when grooming. They too live in the gut and look like flat ribbons. Cats will pass them a section at a time in their faeces, the section wiggles and releases eggs into the environment.


These worms can be transmitted to kittens across the placenta and in their mother’s milk, or picked up from an environment contaminated by the faeces of infested dogs or foxes. They are like tiny beansprouts, which are very hard to see and live in the gut.

Which product should I treat my dog for worms with?

Monthly Endectrid treatment kills roundworms and hookworms. We then need to treat with Quantex tablets for tapeworm every six months, or every three months if your pet scavenges or hunts frequently.

What other parasites may be of concern?


Sheep and deer ticks are prevalent in the countryside. They are pinhead sized when they bite on to your cat, then drink blood until they are the size of a sultana. Ticks should be removed by twisting with a tick removing hook.

Ticks are of most concern for pets travelling to Europe, or other overseas destinations where there are several fatal tick-borne diseases. We recommend a Seresto collar to prevent ticks if you will be travelling with your cat.


Heartworms infest the heart and can be fatal. They are spread by infected mosquitos, therefore fortunately this type of worm is not currently found in the UK. Endectrid will kill heartworms, however we would also advise owners taking their cat abroad to use a Seresto collar which prevents bites from mosquitoes, ticks and flies.
