Symptoms of worms in cats and dogs

Worms in cats and dogs can be dangerous, both to our pets and to our family. While it is true that some pets (particularly adult pets) may not show any outward symptoms of worms, there still are signs you can be on the lookout for to help you catch a worm infestation sooner rather than later.


8 symptoms of worms in cats and dogs to look out for


worms symptoms cats and dogs scooting on their bottoms

1. Scooting on their bottoms

Although a more common symptom of worms in dogs, this can also be seen in cats. If your pet is ‘scooting’ (dragging their bottom along the floor) it could be because of worms or worm eggs irritating the area around the bottom and making your pet feel uncomfortable.

2. Worm eggs in faeces

This is the worm symptom pet owners are most likely to spot. If you see what looks like grains of rice in your pet’s faeces, this is an indicator of tapeworm. These ‘grains of rice’ are egg-filled segments which are shed as the tapeworm matures. Once out in the environment, the segments dry out and break open, releasing thousands of worm eggs into the environment.

3. Diarrhoea and/or vomiting

A worm infestation can cause both diarrhoea and vomiting, which can lead to weight loss and lack of condition for your pet. However, diarrhoea and vomiting can also signify other problems, so you should always seek veterinary advice if your cat or dog is suffering with either.



worms symptoms change in appetite

4. Change in appetite

Roundworms feed off the stomach contents of your pet, so an increase in appetite could be a symptom of worms. Equally, worms can make your pet feel bloated and uncomfortable, leading to loss of appetite. If you notice a change in your pet’s eating habits, particularly for an extended period of time, they should be checked by a vet.

5. Abdominal swelling

This worm symptom is more obvious in kittens or puppies. A heavy intestinal worm infestation can cause bloating, leading to a pot-bellied appearance.




worms symptoms lathargic or lack or energy

6. Lethargic/lack of energy

If your cat or dog is less active than usual, it could be because of a worm infestation. Intestinal worms feed off your pet’s stomach contents, meaning your pet won’t be able to absorb the nutrients they need for energy.

7. Dull coat/lack of condition

Correct nutrition is essential to keep your pet healthy. But, if a worm infestation has taken hold, your pet will not be getting this, resulting in a dry and dull coat.

8. Frequent coughing

Roundworm and lungworm larvae migrate to the lungs, which can cause coughing.




My pet is displaying some symptoms of worms, what should I do?

If your pet is displaying symptoms of worms you need to treat them with a vet strength wormer immediately. These are available from your local pet shop, online retailers and vets.

Most wormers contain a combination of active ingredients and are formulated to kill most common intestinal worms. These products are also known as ‘broad spectrum wormers’. However, some wormers are only designed to target specific types of worms. The age of your pet and their lifestyle (hunter, travelled abroad recently etc.) will impact the type of worm they are likely to have.

You can either choose a broad spectrum wormer, or ask your pet retailer or vet for advice. If you pet is still showing symptoms of worms after treatment, then you should visit your vet.

Worms are particularly dangerous in kittens and puppies due to their immune system not being fully developed. A serious worm infestation can cause intestinal blockages which can sometimes lead to death.

The best way to protect your pet is to follow a regular worming routine.

How do I stop my cat or dog from getting worms?

No product on the market can stop your cat or dog from getting worms. But, it is easy to reduce the spread of worms:

  • Always pick up after your dog and empty your cat’s litter tray

Worm eggs in fresh faeces are not infective. Picking up and disposing of any poo as soon as possible will reduce the risk and spread of worms.

  • Wash your hands after handling faeces

Following good hygiene practice minimises the spread of bacteria, and reduces the chance of you and others picking up worms.

  • Worm your adult cat or dog at least once every three months (kittens and puppies more regularly)

Regular worming keeps your pet and family safe from worms. If your pet hunts, eats prey or scavenges you may need to worm more often, as some prey animals carry worms. Speak to your pet retailer or vet for advice.


While knowing the symptoms of worms to look out for will help, the best way to protect your pet and your family is to follow the steps above. Worming your cat or dog regularly will help stop a worm infestation from taking hold. Disposing of faeces quickly and hygienically helps reduce the amount of worm eggs in the environment.

Remember, even if your pet shows no symptoms of worms it is important to worm them at least once every three months. If you’re unsure which worming product is best for your cat or dog, we have a helpful blog to guide you.
