Worming Treatments for Cats

Wormers

Why worming your cat matters

Worms are a common problem in cats, and many don't show obvious signs of infection. Roundworms, hookworms, and tapeworms can all affect your cat's health—and some can even spread to humans. Regular worming is an easy way to keep your cat healthy and your home protected.

Types of worms in cats

Roundworms are most common and can cause a pot-bellied appearance in kittens. Hookworms attach to the gut and may lead to anaemia, while tapeworms are often seen near the tail or in litter trays. Outdoor cats or those that hunt are more at risk, but indoor cats can be affected too.

How worming treatments work

Wormers come in tablets, spot-ons, or pastes and work by killing the worms living inside your cat. Some products treat just one or two types of worms, while others offer broad-spectrum coverage. Follow the instructions based on your cat's age and weight to get the best results.

How often should you worm your cat?

Kittens should be wormed every 2 weeks until 12 weeks of age, then monthly until 6 months. Adult cats typically need worming every 3 months. If your cat hunts or spends time outdoors, more frequent worming may be needed—your vet can help you decide.

We stock leading worming options like Milbemax, which treats roundworm, hookworm, and tapeworm in one small tablet. Products such as Revolution Plus and Advocate also offer worming as part of an all-in-one monthly spot-on treatment.

Frequently asked questions

How do I know if my cat has worms?

Common signs include weight loss, vomiting, bloated belly, scooting, or seeing segments in their poo. But many cats show no signs at all.

Can I worm my cat at home?

Yes. Most treatments are easy to give at home, especially spot-ons or flavoured tablets.

Do I need to worm indoor cats?

Yes. Worm eggs can still be brought in on shoes or other pets, so indoor cats are not immune.

Can I give my cat a dog wormer?

No. Only use treatments made specifically for cats, as dosages and ingredients differ.

What happens if I miss a worming dose?

Give the missed dose as soon as you remember, and return to your regular schedule. Ask your vet if you're unsure.
