A tick bite on a cat typically looks like a small, raised bump on the skin, often with the tick still attached. Before feeding, ticks are tiny (about 1mm) and easy to miss in fur. After feeding for a few days, they swell to roughly the size of a pea or small bean, up to 1cm long, and become much easier to spot and feel. The bite site itself, once the tick is removed, appears as a small red or pink area that may be slightly swollen.
What a Tick Looks Like on Your Cat
Ticks are egg-shaped, spider-like creatures with six to eight legs depending on their life stage. When you run your hand over your cat’s fur, an attached tick feels like a small, firm bump that wasn’t there before. Many people initially mistake a feeding tick for a skin tag, wart, or even a nipple. The key difference: look closely and you’ll see tiny legs near the skin’s surface where the tick’s head is buried. A skin tag, by contrast, is the same color as the surrounding skin and has no legs or visible head.
An unfed tick is flat and dark brown or black. As it feeds over three to four days, its body balloons and turns grayish or bluish-green as it fills with blood. At that point, it’s unmistakable. If the tick drops off on its own after becoming fully engorged, you may only find the bite mark: a small red spot, sometimes with minor swelling or a tiny scab.
Where to Check First
Ticks prefer areas where they can reach skin easily and where your cat is less likely to groom them off. The most common attachment sites are around the head, neck, ears, and feet. Pay special attention to the folds around the ear base and between the toes. These warm, thin-skinned areas give ticks easy access to blood vessels. If your cat goes outdoors, a quick check of these spots after they come inside can catch ticks before they’ve had time to fully attach and start transmitting pathogens.
What the Bite Looks Like After Removal
Once you remove a tick, the bite site usually appears as a small red mark or raised bump. Mild redness and slight swelling in the first day or two is normal. In most cases, the area heals on its own within a week or so, gradually flattening and losing its redness. Some cats develop a small, firm lump at the site that can persist for a couple of weeks as the skin heals from the irritation of the tick’s barbed mouthparts.
Watch for signs that the bite is not healing normally. If the area becomes increasingly red, swollen, or painful, or develops a draining sore, that points to infection and warrants a vet visit. Applying a pet-safe antiseptic or antibiotic ointment after removal can help keep the site clean.
How to Tell If Mouthparts Are Still Stuck
If the tick breaks during removal, its mouthparts can remain embedded in the skin. This looks like a tiny dark speck at the center of the bite, sometimes surrounded by a bit more redness than you’d expect. The good news: leftover mouthparts generally work their way out on their own over a few days, much like a splinter. Don’t dig at the area with tweezers, as this irritates the skin and raises the infection risk.
Avoid home remedies like petroleum jelly, nail polish remover, or a flame. None of these effectively dislodge embedded mouthparts, and they can burn or irritate your cat’s skin.
How to Safely Remove a Tick
The best tool is a dedicated tick-removal device, which has a narrow slit that slides around the tick’s head. You twist the tool in one direction (clockwise or counterclockwise, either works) to unscrew the barbed mouthparts from the skin. These tools are inexpensive and available at most pet stores.
If you don’t have one, fine-tipped tweezers work. Grasp the tick as close to your cat’s skin as possible, right near the head. Pull upward with steady, even pressure. Never twist when using tweezers, as this can snap the mouthparts off. Avoid squeezing the tick’s swollen body, which can push fluids back into your cat and increase infection risk. Wearing gloves is a good idea since ticks can carry diseases transmissible to humans as well.
Having a second person gently restrain your cat makes the process much smoother. Hold your cat around the shoulders and front limbs, with their back against the helper’s body to prevent them from backing away. Work quickly and calmly.
Tick-Borne Illness Symptoms to Watch For
Cats are less susceptible to tick-borne diseases than dogs. A large U.S. study from 2022 to 2025 found that only about 2.6% of cats tested showed evidence of exposure to at least one tick-borne pathogen, compared to rates roughly four to seven times higher in dogs. Still, the risk is not zero.
The most dangerous tick-borne disease in cats is cytauxzoonosis, carried by lone star ticks and most common in the southeastern and south-central United States. Symptoms typically appear about 10 days after a bite and start vague: low energy, loss of appetite, and difficulty breathing. Infected cats often develop pale or yellow-tinged gums, fever, and dehydration. This disease progresses quickly and can be fatal, so early veterinary treatment is critical.
Cats can also be exposed to the bacteria that cause Lyme disease and anaplasmosis, though clinical illness from these is less common in cats than in dogs. General warning signs of any tick-borne illness include poor appetite, lethargy, stiff or swollen joints, and fever. These symptoms can appear days to weeks after a bite.
Tick Paralysis in Cats
Some tick species produce a toxin that causes progressive muscle weakness. Symptoms typically appear five to nine days after the tick attaches and worsen over the next one to three days. Early signs include wobbliness in the hind legs, reluctance to move, and sitting with the chest in a more upright position than normal. Some cats develop breathing difficulty that resembles feline asthma, with wheezing and visible effort on exhale.
The good news is that tick paralysis tends to be less severe in cats than in dogs and carries a better prognosis. Removing the tick usually leads to improvement, though recovery can take a day or two. If your cat suddenly seems unsteady or weak and has been outdoors recently, checking thoroughly for a hidden tick is an important first step.
