Discover more about intestinal worms in cats and how you can prevent them
None of us like to think of our pets’ carrying worms. Intestinal parasites concern us as owners as they can cause discomfort and illness. Keeping your cat worm-free is not only important for their health, but for the wellbeing of your family too.
In the United Kingdom there are four common types of intestinal worms that infect cats and dogs: roundworms, tapeworms, hookworms and whipworms.
How does my cat get worms?
There are numerous ways cats can become infected with intestinal worms. How they become infected will depend on the species of worm and your pet’s age and lifestyle.
- Roundworms can be ingested by kittens through drinking the milk of their infected mother.
- For older animals, infection often comes from consuming eggs in the environment. This may be when they are outdoors playing or on a walk, but also from the transfer of eggs into the home. Grooming contaminated soil from paws and fur will cause infection.
- Fleas and lice carry immature tapeworms, cats become infected when they groom themselves and ingest the fleas and lice. Therefore, adequate flea control is also important in controlling intestinal parasites too.
- The consumption of uncooked meat or eating infected prey, such as rodents and rabbits, is a source of intestinal worm eggs in cats.
How do I know if my cat has intestinal worms?
When we think of worms, we often imagine long thin tapeworms. The reality is that most adult worms are rarely seen. It is therefore not possible to know if your pet has worms just by looking at them and their faeces. Detection requires microscopic examination of faeces for worm eggs. For this reason, the use of regular preventative treatment is strongly recommended.
What symptoms will intestinal worms cause?
Most cats infected by worms in the United Kingdom show relatively minor symptoms unless the infection is heavy. Kittens are the most vulnerable to ill effects caused by intestinal worms.
Symptoms of infection can include:
- Weight loss
- Potbelly appearance
- Poor coat
- Respiratory problems
A heavy worm burden in kittens can cause an intestinal blockage which can be fatal.
Intestinal worm risks to humans
A disease or infection that can be transmitted to humans from animals is called a zoonosis. Several intestinal worms found in cats and dogs in the United Kingdom are zoonotic.
The roundworms Toxocara cati, found in cats cause toxocariasis in people. Toxocariasis is rare but affects mainly young children as they are more likely to come into contact with eggs in faeces and contaminated soil, and to put their hands in their mouths. Once ingested the eggs hatch inside the human bowel and the larvae can travel throughout the body. These larvae moving through the body can cause a cough and fever, or more severe symptoms such as loss of vision, fatigue, breathing difficulties and seizures.
Regular worming treatment of cats and dogs and immediate disposal of faeces, as well as regular hand washing will help to reduce the risk of toxocariasis,
Some species of tapeworms found in cats are also zoonotic. The most concerning of these is Echinococcus multilocularis. This worm is not currently found in the United Kingdom but is common in continental Europe. Your vet will be able to give you more information about which precautions to take against this parasite.
Treatment and prevention of intestinal worms in cats
Intestinal worm eggs are common and widespread in the environment. Almost all cats will be infected at some point during their lives. High rates of infection and a lack of obvious symptoms is the reason regular worming treatment should be given to all cats.
Drontal and Dronspot for Cats kill every type of intestinal worm commonly found in UK cats, dosing every three months will be sufficient control for most pets. with a regular flea treatment is also necessary to prevent reinfection of tapeworms.
Pets with no access to the outdoors should still be treated every three months as eggs will still be transferred into the home by shoes, bike and buggy wheels.
High-risk pets, including kittens younger than 6 months, pregnant and lactating queens, as well as hunters and those eating raw meat may require more frequent dosing. You can discuss your cat’s worming needs with your vet.
Removing pet faeces immediately and cleaning the environment will help to prevent an accumulation of worm eggs.
