The most common forms of intestinal worms are roundworms and tapeworms, but there are in fact 8 different types which can infect your cat, and in some cases spread to humans.
In small numbers, worms are not very harmful and cats often show no symptoms of having them. However, in large numbers worms can cause vomiting, diarrhoea, weight loss and even death.
For these reasons, cat owners should regularly treat their cats and kittens to help prevent or eliminate worms. In this guide we explore the different worming treatments available and review the best cat wormers in the UK that will help keep your cats and kittens healthy.

Best Worming Tablets for Cats & Kittens: Beaphar WORMclear for Cats
Our Rating: 5/5Check Price
Beaphar Worming tablets can be given to cats and kittens from 6 weeks old and effective on your cat in one dose. The tablets are proven to kill roundworms and tapeworms (which encompasses the 8 common types of intestinal worms).
The box comes with two meaty flavoured tablets (film coated) which will last you between 1 month and 6 months depending on the age of your cat. Kittens should be treated every fortnight until 2-3 weeks after they have been weaned. For adult cats to remain worm free they should be treated once every 3 months.
The tablets measure approximately 1cm in diameter, but can be easily cut using the ridge on the tablet. When cut, they maintain their shape but can be easily crushed using the side of a knife if you wanted to add them to your cats food (we did this as our cats refuse to swallow!).
For the money, these tablets are exceptionally cheap, and make worming your cat affordable and efficient.
Best Kitten Wormer: Beaphar Worming Syrup for Kittens
Beaphar Worming syrup is designed to treat roundworm only (which is the main worm found in kittens under 6 months, tapeworm typically is only found in cats 6 months+) which makes this the perfect wormer for kittens. The syrup is suitable for kittens from 2 weeks old. The bottle comes with a pump dispenser which makes measuring the correct dose and applying it into the corner of your kittens mouth a breeze.
The pump cleverly measures exactly 1.1ml per pump, and comes with a simple table to determine how many pumps per dose are required for your cat. We used this syrup on both kittens and puppies and found it an excellent way of worming.
Given how difficult it can be to worm kittens this syrup solves those worries with the syrup able to be put straight into their mouth, or mixed with milk or food. Given that most tablets aren’t suitable for kittens under 6 weeks, we think this syrup is the best fit for very kittens.

Where do cats get the worms from?
There are different sources of worms, and it depends on the type of worms. For example;
- Heartworms are transferred by mosquitos,
- Tapeworms are obtained by eating contaminated food,
- Lungworms are acquired by ingesting a host infected with the worm, and they live in the lungs,
- Hookworms live in the intestines and are obtained by eating contaminated food or through skin contact with an infected animal,
- Roundworms are acquired through ingestion of contaminated food and for kittens, they get the worms through the mother’s milk when they breastfeed.
The most common types of worm are roundworm and tapeworm.
- Roundworm: These are often easier to see. They are long and thin and often visible. They can grow to up to 10cm long, though this length is pretty uncommon. They are white and can be seen in faeces, and sometimes around the cat’s anus.
- Tapeworm: Tapeworm are smaller and look like small white grains. These can be visible around the cat’s anus, faeces or in their bedding.
If your cat is infected, they will also display physical symptoms.
- Weight loss even if they are eating normally.
- Distended stomach.
- Their fur can lose its sheen and appear coarse and rough.
- The discomfort can cause your cat to drag its bottom across the floor, so if you see them doing this, check for worms.
- If your cat is wheezing or coughing then visit your vet. This can be a symptom of lungworm which can be fatal if left untreated.
Rather than wait until your cat shows signs of having worms, try to prevent them if possible.
- Make sure you treat them for fleas as these are a common carrier. If you prevent them getting fleas, you can prevent them getting worms.
- Worm them regularly, even if they show no symptoms. Your vet will advise the best course of treatment but as a guide:
- Kittens: Treat them monthly from 6 weeks old, then from 6 months old, treat them every 3 months.
- Adult cats: Worm them every 2 to 6 months.
Basic hygiene can also help prevent worms.
- Don’t leave food lying around too long if it is not eaten. Always throw it away and put fresh food down.
- Water bowls and food bowls should be cleaned and disinfected regularly, but make sure you only use animal friendly disinfectant.
- Make sure your house is regularly cleaned so your cats have a healthy environment.
Worms may not be the most pleasant condition that a cat can get, but they are usually easily treated and do not cause permanent damage. If you think your cat may have worms, don’t leave it too long to treat them and always get advice on the best treatment to give them. Prevention is always better than cure, so getting into the habit of regular worming and make sure you never miss a treatment.
Deworming cats is a crucial step in ensuring your cats remain healthy. Worms can significantly affect your cat’s health since they compete with your cat for food. Therefore, if your cats are not dewormed regularly, they will start to lose weight.
Some worms like hookworms accumulate in the small intestines and block the intestines. This is a harrowing experience for any cat due to constant abdominal pains, bloating and constipation. The intestinal obstruction will require your cat to be operated on to remove the worms. As a cat lover, this is the last thing you want your cat to go through.
As a cat owner there are a number of things to remember to do if you believe your cat is showing signs of worms:
- Find out the type of worms your cat is likely to have depending on the source of the worms
- Look for the best medication that is effective and cost efficient at the same time
- Identify the best route for administering the cat wormer. It can either be tablets or topical skin applications, depending on what your cat likes
- Look for other ways of preventing future worm infestations. For example, ensure your house and bowls are clean so your cat won’t have a chance of ingesting contaminated food
