The Importance of Deworming Indoor Cats
Even though indoor cats have limited exposure to the outdoors, they are still at risk of contracting worms. Regular deworming is essential for maintaining their overall health and preventing potential complications.

How Indoor Cats Can Contract Worms
Many cat owners assume that indoor cats are safe from parasites, but worms can still find their way inside. Here’s how:
- Fleas: Fleas carry tapeworm eggs. If your cat ingests an infected flea while grooming, they can develop an infestation.
- Contaminated Surfaces: Shoes, clothing, or other pets can bring worm eggs into the home.
- Prey: Indoor cats that hunt insects or rodents may contract parasites.
- Mother to Kitten Transmission: Infected mothers can pass worms to their kittens at birth.
Common Types of Worms in Cats
Cats can be affected by several types of worms, including:
- Roundworms: The most common intestinal parasite in cats, passed through infected faeces.
- Tapeworms: Often transmitted through fleas, these attach to the intestinal wall.
- Hookworms: These parasites feed on blood and can cause anaemia.
- Whipworms: Less common but still a concern, these affect the large intestine.
Signs and Symptoms of Worm Infestation
Detecting worms in cats can be tricky, but some common signs include:
- Vomiting and diarrhoea (sometimes with visible worms)
- Weight loss despite a healthy appetite
- A bloated or distended belly
- Dull coat and poor overall condition
- Lethargy and weakness
- Visible worm segments near the anus or in faeces (e.g., tapeworms appear like rice grains)
Deworming Kittens vs. Adult Cats
- Kittens should be dewormed starting at two weeks old and every 2-3 weeks until they are 8-12 weeks old.
- Adult Cats should follow a regular deworming schedule based on their risk level, usually every 3-6 months.
Choosing the Right Deworming Medication
Several deworming treatments are available:
- Oral Medications: Tablets or liquids that kill worms inside the intestines.
- Topical Treatments: Applied to the skin to eliminate internal and external parasites.
- Injectable Dewormers: Administered by vets for severe infestations.
Common Active Ingredients:
- Praziquantel: Effective against tapeworms.
- Pyrantel Pamoate: Targets roundworms and hookworms.
- Fenbendazole: Broad-spectrum treatment for various worm types.
Recommended Deworming Schedule
- Low-risk indoor cats: Every 6-12 months
- Indoor cats exposed to other pets or fleas: Every 3-6 months or as advised by your veterinarian. The RSPCA advises treating pets for roundworms from a young age and including tapeworm treatment for adults, highlighting the need for tailored approaches. https://www.rspca.org.uk/adviceandwelfare/pets/general/worms
- Kittens and high-risk cats: More frequent treatments as recommended by a vet
Preventative Measures to Protect Your Cat
Preventing worm infestations is just as important as treating them. Here’s how you can reduce the risk:
- Regular Flea Control: Fleas are common carriers of tapeworms, so consistent flea prevention is essential.
- Clean Litter Boxes Daily: Worm eggs can be shed in faeces, so keeping litter boxes clean minimises exposure.
- Wash Hands and Clean Surfaces: Good hygiene helps prevent the spread of worm eggs.
- Avoid Feeding Raw Meat: Raw diets can carry parasites that infect cats.
- Routine Vet Check-ups: Regular veterinary check-ups, as promoted by Cromwell Vets (https://www.cromwellvets.co.uk/pet-help-advice/cats/52-worms-in-cats) , allow for early detection and treatment of parasites, safeguarding your cat’s health.
Cost of Deworming (UK Prices)
The cost of deworming a cat in the UK varies based on the type of medication and veterinary services:
- Over-the-counter dewormers: £5-£15 per treatment
- Prescription dewormers (from a vet): £20-£50 per treatment
- Veterinary consultation & faecal tests: £40-£80
- Monthly preventative treatments (flea & worm combo): £10-£30 per month
Many pet owners opt for monthly flea and worm treatment plans, which range from £10-£20 per month and often include regular vet check-ups.
The Impact of Flea and Tick Treatments on Worm Control
Since fleas are a primary carrier of tapeworms, using a flea prevention plan is crucial. Many broad-spectrum parasite treatments cover both fleas and worms.
Zoonotic Potential: Can Humans Get Worms from Cats?
Some cat worms are zoonotic, meaning they can infect humans. Roundworms and hookworms can be transmitted through contact with infected faeces or contaminated surfaces. Good hygiene and regular deworming help protect your family.
Monitoring Your Cat’s Health After Treatment
After deworming, monitor your cat for:
- Temporary gastrointestinal upset (mild vomiting or diarrhoea)
- Increased activity and appetite (as worms are expelled)
- The presence of dead worms in the stool
- Continued symptoms (which may require a follow-up vet visit)
Frequently Asked Questions
How often should I deworm my indoor cat?
It depends on risk factors, but most indoor cats should be dewormed every 3-6 months.
What are the side effects of deworming medications?
Common side effects include mild vomiting, diarrhoea, or temporary lethargy.
Can my cat get worms from other pets?
Yes. If your cat lives with a dog or other animals that go outside, they are at higher risk of exposure.
What should I do if I find worms in my cat’s stool?
Consult your vet immediately for proper diagnosis and treatment.
Are there natural alternatives to deworming medications?
Some natural remedies (e.g., pumpkin seeds, diatomaceous earth) are suggested, but they are not as effective as vet-approved dewormers.
Conclusion
Deworming your indoor cat is an essential part of responsible pet care. By understanding the risks, symptoms, and treatment options, you can ensure your feline friend stays healthy and parasite-free. Regular veterinary visits, proper hygiene, and preventative treatments will help keep worms at bay.
