Ticks on Cats: Are Cats Really Less at Risk?

By Sarah Bennett, Certified Animal Nutritionist

📌 Common Misconception: Many cat owners believe their pets are naturally resistant to ticks or rarely pick them up. While cats do groom ticks off efficiently and may be less commonly infested than dogs, they are absolutely susceptible — and the diseases ticks transmit can be just as serious. Outdoor and semi-outdoor cats in tick-endemic areas need proper protection.

The question of whether cats are less at risk from ticks than dogs is nuanced. Behavioural, biological, and grooming differences do mean cats are less frequently heavily infested — but "less frequently" is not the same as "safe." Cats roam the same environments as dogs, share the same tick populations, and are susceptible to several serious tick-borne diseases. Here is what every cat owner needs to know.

Why Cats Seem Less Affected: The Grooming Factor

Cats are extraordinarily effective self-groomers. Their barbed tongues and flexible spines allow them to reach nearly every part of their body, including areas where ticks commonly attach — behind the ears, on the neck, and between the legs. Cats routinely remove ticks during grooming before the tick has had sufficient time to feed and transmit pathogens. This mechanical removal is genuinely protective and explains why cats present with overt tick infestations less often than dogs in clinical settings.

However, this protection is imperfect. Ticks found attached to cats are often located in spots the cat cannot easily groom: inside and around the ear canal, on the face, under the chin, or high on the neck. Additionally, older cats, obese cats, or those with arthritis or other mobility issues may groom less effectively, leaving them significantly more vulnerable. Kittens also lack the grooming proficiency of adults and may carry higher tick burdens.

A 2019 surveillance study published in Parasites & Vectors (PubMed) found that cats in endemic European regions carried ticks at rates that were significant and clinically underappreciated, with Ixodes ricinus being the dominant species recovered.

Tick Lifecycle and How Cats Encounter Them

The ticks most commonly found on cats in Europe and the UK are Ixodes ricinus (the sheep tick or castor bean tick), the same species that transmits Lyme disease, tick-borne encephalitis, and anaplasmosis. This tick has a three-host lifecycle spanning 2–3 years:

Larvae hatch from eggs in leaf litter and feed on small mammals and birds. Cats that hunt in gardens, hedgerows, or woodland edges encounter larval ticks regularly.
Nymphs are tiny (1–1.5 mm) and easily overlooked. They are active from spring through autumn and feed on a wide range of hosts, including cats.
Adult ticks are larger and more visible. Female adults, engorged after feeding, may reach 10–12 mm. Cats pick up adults in the same environments as dogs — long grass, bracken, leaf litter, and woodland margins.

Ticks do not jump or fly. They quest on vegetation, extending their forelegs to grip onto passing animals. A cat that roams through grass or undergrowth even briefly can pick up multiple ticks in a single outing.

Tick-Borne Diseases in Cats

While dogs are more studied for tick-borne diseases, cats are susceptible to several important pathogens:

Cytauxzoonosis (Cytauxzoon felis): A severe and often fatal protozoan disease in North American cats, transmitted by the lone star tick. Cats develop fever, difficulty breathing, and anaemia, with high mortality rates even with treatment.
Haemobartonellosis (Mycoplasma haemofelis): A bacterial infection of red blood cells causing haemolytic anaemia. Clinical guide" title="Signs Dog Is Dying Guide">signs include lethargy, pale gums, weight loss, and fever. Transmitted by ticks and fleas. The PDSA notes this is one of the most significant tick-associated diseases in UK cats.
Anaplasmosis (Anaplasma phagocytophilum): Cats can be infected with the same species that causes anaplasmosis in dogs, though clinical disease appears to be less common. Signs include fever, lethargy, and loss of appetite.
Babesiosis: Rare in domestic cats but documented. More common in wild felids.
Lyme Disease (Borrelia burgdorferi): Cats can be seropositive (showing antibody evidence of exposure) but rarely develop the clinical signs seen in dogs and humans. Cats appear to have a degree of natural resistance to overt Lyme disease, though the mechanisms are not fully understood.

EU and UK Risk Areas for Cats

The risk for cats mirrors that for dogs, as they share the same environments and tick species. High-risk zones in the UK include:

The New Forest, Hampshire
Thetford Forest, Norfolk/Suffolk
Exmoor and Dartmoor
The Lake District and Yorkshire Dales
Scottish Highlands and Islands
Coastal heathland throughout Wales and the South West

Across Europe, Ixodes ricinus is found from Portugal to Scandinavia. Dermacentor reticulatus is expanding westward from Central Europe. The ESCCAP (guide" title="Pet Insurance in Europe: Country-by-Country Comparison">European Scientific Counsel Companion Animal Parasites) publishes updated risk maps and guidance for tick-borne disease prevention across EU member states. Climate data shows tick-active months extending earlier in spring and later in autumn across northern and western Europe, as reported by BBC Health.

Tick Check and Safe Removal in Cats

Check your cat for ticks whenever it returns from outdoors, especially if it has been in high-risk habitat. Run your fingers slowly through the coat, pressing gently against the skin. Common attachment sites in cats include:

Inside and around the ear
Around the face and chin
Under the collar
Between the toes and paw pads
In the groin and armpits
Around the tail base

To remove a tick from a cat, use a tick hook (such as the O'Tom Tick Twister) rather than tweezers where possible — cats' skin is more mobile and delicate, and a hook provides more control. Pull steadily straight upward without twisting or squeezing the body. Clean the bite site with antiseptic. Monitor for signs of illness over the following weeks and contact your vet if your cat develops fever, lethargy, or loss of appetite.

Tick Prevention Products Safe for Cats

This is where cat owners must be extremely careful. Many tick preventatives designed for dogs are profoundly toxic-to-dogs" title="toxic-to-dogs" title="Is Aloe Vera Toxic to Dogs?">toxic-to-dogs" title="Is Yew Toxic to Dogs?">Is Yew Toxic to Dogs?">toxic to cats. Permethrin and other pyrethroids are acutely toxic to cats — even residue from a recently treated dog can cause seizures and death in cats that groom the dog or share sleeping areas.

Cat-safe tick prevention options include:

Seresto collar (flumethrin + imidacloprid): Licensed for cats; provides months of sustained protection against ticks and fleas.
Bravecto Plus (fluralaner + moxidectin): A spot-on licensed for cats in multiple markets, providing 3-month flea and tick protection.
Broadline (fipronil + (S)-methoprene + eprinomectin + praziquantel): Provides broad-spectrum parasite control including ticks.
Selamectin spot-ons (Revolution/Stronghold): Some efficacy against ticks, though not as the primary indication.

Always confirm with your veterinarian that any product is licensed for use in cats before applying. Never use products labelled for dogs only.

Key Takeaways

Cats groom ticks off efficiently, but this does not make them immune — ticks still attach, especially in hard-to-reach spots.
Older, obese, arthritic, or young cats groom less effectively and face higher tick burden risk.
Ixodes ricinus is the primary tick species affecting cats across the EU and UK, with range expanding due to climate change.
Haemobartonellosis (Mycoplasma haemofelis) is the most clinically significant tick-associated disease in UK cats.
NEVER use permethrin or dog tick products on cats — they can be fatal. Use only cat-licensed products.
