Can my cat get Lyme disease from a tick bite the way a dog can?

Realistically, no. Cornell's Feline Health Center notes that cats are highly resistant to the bacteria that cause Lyme disease and rarely show signs, and that clinical Lyme disease has never been seen in a cat outside of a laboratory setting. So while a tick can certainly bite an outdoor cat, Lyme disease itself is not a meaningful real-world concern for cats the way it is for dogs. That does not mean tick bites in cats are risk-free, though — other tick-borne diseases do affect cats, which is why any tick-exposed cat that becomes unwell should still be seen by a veterinarian rather than assumed to be fine because Lyme isn't a factor.

What tick-borne diseases actually matter for cats, then?

Several conditions are more relevant to cats than Lyme is. Cytauxzoonosis, sometimes called bobcat fever and transmitted mainly by the lone star tick, is severe and often fatal, causing high fever, lethargy, anemia, jaundice, and breathing difficulty. Hemobartonellosis, also known as feline infectious anemia, causes life-threatening anemia with pale gums and rapid breathing. Ehrlichiosis, anaplasmosis, babesiosis, and tularemia can also affect cats, typically causing fever, anemia, lethargy, and reduced appetite. Because feline signs can be subtle at first and some of these diseases progress quickly, a tick-exposed cat showing any combination of these signs needs prompt veterinary evaluation rather than home monitoring alone.

My outdoor cat had a tick and now seems tired — is that an emergency?

Mild tiredness alone generally falls into the call-your-vet-soon category rather than an immediate emergency — describe what you're seeing and let your veterinarian help decide on timing and whether testing makes sense. It becomes urgent, meaning see a vet now, if your cat's gums look pale or yellow, breathing becomes labored or open-mouthed, your cat collapses, or a high fever develops. Those signs can point to rapidly progressing anemia or a disease like cytauxzoonosis, both of which are far more dangerous in cats than the vague early fatigue alone. When in doubt with a tick-exposed cat, a same-day call to your veterinarian is the safer path.

Tick-Borne Disease in Cats: Common Symptoms to Watch For

Your vet's desk

Feline tick-borne disease is genuinely uncommon and can be hard to interpret — diagnosis belongs to your veterinarian, not a symptom checklist.

Don't panic about Lyme disease in cats, it's essentially not a real-world concern — but do take pale gums, breathing changes, or lethargy in a tick-exposed cat seriously.

Call your vet soon for vague signs in a tick-exposed cat

Feline tick-borne illnesses cause non-specific signs like fever, lethargy, and reduced appetite, but a few — including cytauxzoonosis and severe anemia — are rapidly life-threatening, so vague signs warrant a prompt call rather than a wait-and-see approach.

Escalate when

Pale or yellow gums, open-mouth or labored breathing, collapse, or a high fever appear — see a vet now.

This hub owns pet-specific prevention

The general biology, the mosquito Q&A, the pet-product safety — those live in siblings that already earn them. Here's exactly where.

General tick biology lives in our ticks & fleas FAQ. Note that tick preventives for cats must be vet-selected — some dog products, including permethrin-based ones, are toxic to cats; see our pet-product safety guidance.

Local to New Hampshire

How this calibrates for NH

New Hampshire context

New Hampshire's blacklegged and American dog ticks readily bite cats that go outdoors. The lone star tick that transmits cytauxzoonosis is expanding in New England, with documented establishment on Martha's Vineyard, Massachusetts, but it is not yet established statewide in NH according to current surveillance — a real but still limited local risk.
