Parasite treatments for cats: spot-ons, collars or tablets?
Fleas, ticks and intestinal worms are not just a problem for outdoor cats: an indoor cat can be contaminated by parasites carried in on the soles of your shoes. Parasite protection is therefore a pillar of feline health, provided you choose the right product and use it correctly.
What should you protect your cat against?
- Fleas: the number one external parasite, a source of itching and allergies and a carrier of certain worms.
- Ticks: mainly a concern for cats with outdoor access, they can transmit diseases.
- Intestinal worms: roundworms and tapeworms in particular, which require regular deworming at a frequency that depends on lifestyle.
Treatment frequency varies with age, outdoor access and the presence of children in the home: your vet is the one who sets the right protocol. A hunting cat, for instance, will need deworming more often than a strictly indoor cat.
The available formats and their strengths
The spot-on pipette remains the most widespread format: a few drops on the skin of the neck, out of reach of the tongue, for protection that generally lasts a month. Tablets suit cats that accept a morsel hidden in wet food. Antiparasitic collars offer long-lasting action, but absolutely require a secure quick-release system for a cat that goes outside. Sprays are handy for one-off treatments, particularly for kittens, on veterinary advice. Budget-wise, expect roughly 5 to 12 € per pipette and 15 to 40 € for a collar, with variations between pet-shop and veterinary ranges.
The mistakes that can cost dearly
- Never use a dog product on a cat: some canine treatments based on permethrin are highly toxic, even fatal, to felines.
- Do not underdose or overdose: the cat’s actual weight determines the dose.
- Do not forget the environment: in a flea infestation, most of the parasites live in the home; beds, blankets and the cat tree must be treated or washed.
- Do not drop your guard in winter: indoor heating keeps fleas active all year round.
Veterinary products or supermarket brands?
Treatments dispensed by vets and pharmacies generally benefit from more recent molecules and personalised guidance. Pet-shop products can be adequate for light prevention, but their effectiveness varies more. In the case of a confirmed infestation, a very young kitten, a pregnant queen or a sick cat, veterinary advice is essential before any treatment. To round out the care routine, regular brushing and hygiene help you spot intruders early: find our guides in the cat care and grooming section, along with our article on brushing and shedding control.
