Yes, ticks bite both dogs and cats. The AVMA confirms that adult ticks actively seek larger mammal hosts, and dogs and cats are among their most common targets across North America. Ticks are ectoparasites — they insert their mouthparts into the skin surface, anchor with a glue-like secretion, and feed on blood for up to several days before dropping off. Any pet that spends time outdoors is at risk, and the brown dog tick (Rhipicephalus sanguineus) is the only tick species capable of completing its entire lifecycle indoors, putting even indoor pets within reach.
The risk is not equal between species. Dogs are highly susceptible to tick-borne illnesses — including Lyme disease, anaplasmosis, ehrlichiosis, and Rocky Mountain spotted fever. Cats carry a biological resistance to most of these pathogens, including Borrelia burgdorferi, the bacterium behind Lyme disease, and rarely develop symptoms even when bitten by infected ticks. The critical exception is cytauxzoonosis ("bobcat fever"), caused by Cytauxzoon felis and transmitted by the lone star tick (Amblyomma americanum) — often fatal in cats and without an equivalent disease burden in dogs.
Tick bites are difficult to detect on fur-covered animals. The bite site typically appears as a small red bump or scabby sore, and signs of tick-borne illness generally don't surface for 7 to 21 days after the bite (CDC). On dogs, check around the ears, neck folds, between the toes, and under the front legs. On cats, focus on the head and neck, where self-grooming reaches less effectively. To remove an attached tick, use fine-tipped tweezers placed as close to the skin as possible and pull upward with steady pressure — never twist or jerk.
Pets bring ticks indoors. Research shows pet-owning households face a 1.83 times greater risk of finding a tick crawling on a person, and a 1.49 times greater risk of tick attachment, even when tick-prevention products are actively in use (Jones et al., cited by Dr. Daniel Cameron, MD).
Why Dogs and Cats Face Different Tick-Borne Disease Risks
Dogs are the higher-risk species by a significant margin — but the reasons cats are more protected are less understood than most pet owners realize. An eight-year surveillance study published in Frontiers in Veterinary Science (Duplaix et al., 2021) analyzed 13,733 blacklegged ticks collected from 12,547 animals in Quebec. Of the 1,774 tick-infested cats in the study, 22.6% were bitten by at least one Borrelia burgdorferi-positive tick — yet clinical Lyme disease in cats has not been documented outside laboratory settings. Dogs in the same study showed similar pathogen-exposure rates (18.4%), but an estimated 5–10% of infected dogs go on to develop diagnosable illness (AVMA).
Cats' resistance appears to stem from a combination of immune system differences, grooming behavior, and tick host preferences. A UK prevalence study found ticks on 6.6% of cats compared to 30% of dogs. That said, cats are not universally protected: cytauxzoonosis carries a fatality rate that can exceed 50% without aggressive veterinary intervention (Cornell Feline Health Center).
Which Tick Species Most Commonly Bite Pets — and Where They Live
Four species account for the majority of tick bites on dogs and cats in the United States, and each carries distinct disease risks. The blacklegged tick (Ixodes scapularis), the primary vector of Lyme disease, is expanding its geographic range due to climate change. The American dog tick (Dermacentor variabilis) is widespread east of the Rocky Mountains and transmits Rocky Mountain spotted fever. The brown dog tick (Rhipicephalus sanguineus) is unique in that it can survive and reproduce entirely indoors. The lone star tick (Amblyomma americanum) is the vector for the often-fatal cytauxzoonosis in cats and is prevalent across the South and Midwest.
White-footed mice are a critical part of the tick transmission cycle — they serve as the primary reservoir host for Borrelia burgdorferi and are the main blood source for Ixodes larvae and nymphs. Rodent activity near your home meaningfully raises tick exposure risk for both pets and people. Resources such as mouse poop images can help homeowners identify whether rodents are active on their property and contributing to tick pressure in the yard.
The Permethrin Problem: Why Dog Tick Products Can Kill Cats
Never apply a canine tick product to a cat — even brief exposure to permethrin can be fatal. Permethrin is a synthetic pyrethroid widely used in over-the-counter dog acaricides, including spot-on treatments. Dogs metabolize it safely via liver enzyme pathways. Cats lack the enzymes required for glucuronidation and ester hydrolysis, so the compound accumulates and causes severe neurological toxicity — tremors, seizures, and potentially death if untreated (ASPCA Pro).
The risk in mixed-species households extends beyond direct application. A cat that grooms or sleeps against a dog recently treated with a permethrin-based product can absorb a toxic dose through the coat. Keep cats separated from treated dogs for at least 48 to 72 hours, and consult a veterinarian before selecting any tick-prevention product for a home with both species. Safe cat-labeled options exist, including specific isoxazoline-class oral products — but label verification is non-negotiable.
How Ticks Move from Your Pet Into Your Home — and Stay There
Pets returning from outdoors can seed a tick infestation inside a house even when no outdoor population is visible near the property. The brown dog tick (Rhipicephalus sanguineus) is uniquely adapted to indoor survival and can establish breeding populations in wall voids, furniture, and pet bedding. Unlike other tick species that require specific outdoor microhabitats to complete their lifecycle, R. sanguineus thrives in the warmth of a heated home, and a single heavily infested dog is sufficient to start an infestation.
When ticks are found on pets, household members face a 2.69 times greater risk of ticks crawling on them compared to pet-free homes (Jones et al.). Tick prevention on the pet reduces — but does not eliminate — human exposure indoors. Vigilance for early indicators of any indoor pest activity matters, and, as with how to see bed bugs, the earlier a problem is identified, the more limited the required intervention.
Recognizing Signs of Tick-Borne Illness in Dogs and Cats
Because tick-borne disease symptoms take 7 to 21 days to appear, a pet can seem completely normal for weeks after a bite before becoming seriously ill (CDC). In dogs, watch for fever, lethargy, reduced appetite, joint pain or lameness, and swollen lymph nodes. In severe cases of ehrlichiosis or babesiosis, bruising or pale gums may appear. The Merck Veterinary Manual notes that heavy tick infestations can cause anemia from blood loss alone, separate from any pathogen transmission.
In cats, tick-borne illness is less common but deteriorates rapidly when it does occur. Cytauxzoonosis presents as sudden fever, lethargy, and loss of appetite — with severe decline within days of onset. Any cat with tick exposure history showing these symptoms warrants emergency veterinary evaluation.
When Should You Call a Pest Control Professional for Ticks?
Tick prevention on your pet is your veterinarian's domain. Ticks in and around your home are a pest management problem. Professional yard and perimeter treatment is the appropriate next step when:
- You have found ticks on your pet more than once within a single season
- A household member has been bitten by a tick that was not visibly carried in on a pet (suggesting an established outdoor population)
- A live tick has been found inside your home following an event unrelated to outdoor travel
- Your yard includes tall grass, leaf piles, wood stacks, or brush adjacent to areas where pets or children spend time
- You have a dog that is an indoor-outdoor pet and live in a region where Rhipicephalus sanguineus is common
A licensed pest professional can identify harborage zones around your property, apply targeted acaricide treatment to the perimeter, and — in confirmed indoor infestations — address the wall voids and resting surfaces where brown dog ticks establish breeding colonies.
If two or more of the conditions above describe your property, a licensed exterminator austin tx can perform a property assessment before peak tick season. Before scheduling any professional home treatment, preparation questions — including what to do with food storage, addressed in resources like university extension fumigation refrigerator food safe — are worth reviewing in advance.

FAQ
Q: Can indoor cats get ticks?
A: Yes. Cats kept entirely indoors can still be exposed if the brown dog tick (Rhipicephalus sanguineus) is introduced on another pet, on clothing, or through gaps in the home's structure. This species can survive and reproduce entirely inside a house. Indoor-only cats face lower overall risk but are not fully protected without periodic tick checks.
Q: Can my dog or cat give me Lyme disease directly?
A: No. The CDC confirms that neither dogs nor cats spread Lyme disease directly to people. However, ticks carried indoors on a pet can detach and bite household members. Pet-owning homes face 1.83 times the risk of tick crawl-on contact and 1.49 times the risk of tick attachment compared to pet-free homes, even with prevention products in use (Jones et al.).
Q: How long does a tick have to be attached before it can transmit disease?
A: For Lyme disease, a blacklegged tick generally must be attached for at least 36 to 48 hours to transmit Borrelia burgdorferi. Rocky Mountain spotted fever can be transmitted more quickly — within hours of attachment in some cases. Removing ticks within 24 hours significantly reduces transmission risk across most tick-borne diseases.
Q: Do I need tick prevention for a cat that stays indoors?
A: Risk is lower for indoor-only cats, but it is not zero, particularly in homes with outdoor dogs. Most veterinarians recommend tick prevention for cats in moderate-to-high-risk regions. Never use a permethrin-based product on a cat — consult your vet for cat-labeled, species-safe options.
Quick Reference: Tick Bites in Dogs and Cats
- Both dogs and cats are bitten by ticks; adult ticks actively seek larger mammal hosts, and both species are primary targets across North America (AVMA).
- Dogs are significantly more susceptible to tick-borne illness than cats, which carry a natural biological resistance to most pathogens including Borrelia burgdorferi (the Lyme disease bacterium).
- In an eight-year Quebec surveillance study, 22.6% of tick-infested cats were exposed to Borrelia-positive ticks, yet clinical Lyme disease in cats has never been confirmed outside laboratory settings (Duplaix et al., 2021, Frontiers in Veterinary Science).
- Cytauxzoonosis ("bobcat fever"), transmitted by the lone star tick, is often fatal in cats and carries no equivalent risk in dogs — making it the primary tick-borne danger specific to felines.
- Permethrin — a pyrethroid used in most dog tick products — is toxic to cats because felines lack the liver enzymes needed to metabolize it; even indirect exposure through a treated dog can be lethal.
- Signs of tick-borne illness in pets typically do not appear for 7 to 21 days after a bite, so monitor any pet with known tick exposure for changes in appetite, energy, or movement over the following three weeks (CDC).
- Pet-owning households face a 1.83 times greater risk of tick crawl-on contact and a 1.49 times greater risk of tick attachment than pet-free homes, even when prevention products are actively in use (Jones et al.).
- Professional perimeter treatment is appropriate when ticks are found repeatedly on pets within a single season, or when any live tick is discovered inside the home.
