Finding out your cat has lice is unsettling, but take a deep breath. Cat lice (Felicola subrostratus) are tiny, wingless insects that live only on cats, so you and your dog are safe. They spread through direct contact or shared bedding and cause scratching, a scruffy coat, and visible white eggs (nits) glued to the fur. The good news: with a little patience and a thorough home approach, you can clear the infestation completely. Here is exactly how to get rid of cat lice at home, step by step.
1. Confirm It Is Lice, Not Fleas or Dandruff
Before treating anything, make sure you are dealing with lice. Lice are pale, slow-moving, and about the size of a sesame seed. They cling to the base of the hair shaft. Nits look like white specks stuck to individual hairs, unlike dandruff which flakes off easily. Part your cat’s fur in a few spots, especially around the head, neck, and tail base. If you see tiny bugs crawling or eggs that won’t shake loose, it is lice. If you are unsure, ask your vet to confirm with a quick skin scrape. Misidentifying the pest means using the wrong treatment, so this step matters.
2. Use a Fine-Toothed Nit Comb to Remove Lice and Eggs
The most effective at-home tool is a metal nit comb with very fine teeth. Comb your cat daily over a white paper towel or a light-colored surface so you can see what falls off. Work in small sections, starting at the skin and pulling outward. Dip the comb in warm, soapy water after each pass to kill any lice you catch. Focus on the neck, ears, and base of the tail where lice love to hide. This manual removal is tedious but critical, because no topical treatment kills all the nits in one go. Repeat this combing every day for at least two weeks to catch newly hatched lice before they lay more eggs.
3. Choose a Safe, Vet-Informed Topical Treatment
Do not use flea treatments, dog lice products, or essential oils on your cat, as many are toxic to cats. Instead, ask your veterinarian for a product labeled specifically for cat lice. Options often include fipronil or selamectin spot-on treatments that kill adult lice and some nymphs. Apply the treatment exactly as directed, usually between the shoulder blades where your cat cannot lick it off. Never use a permethrin-based product, which can cause severe neurological reactions in cats. If your cat has skin irritation from scratching, a gentle bath with a cat-safe oatmeal shampoo can soothe the area, but check with your vet first.

Lice cannot survive off the host for more than a few days, but eggs can hatch for up to 10 days. That means you must treat both the cat and the environment at the same time to break the life cycle.
4. Wash All Bedding, Toys, and Soft Surfaces
Lice and nits can live on blankets, cat beds, and even your cat’s favorite plush mouse. Strip all bedding and wash it in hot water (at least 130°F or 54°C) with a regular detergent, then dry on high heat for at least 30 minutes. Vacuum every carpet, rug, sofa cushion, and cat tree thoroughly. Empty the vacuum canister or discard the bag outside immediately. For items that cannot be washed, like a scratching post, seal them in a plastic bag for two weeks to starve any lingering lice. If your cat shares your bed, wash your own sheets and pillowcases too. This deep clean is non-negotiable for stopping reinfestation.
5. Treat All Cats in the Household
Cat lice are highly contagious among felines. Even if only one cat shows symptoms, all the cats in your home are likely exposed. Treat every cat with the same topical product recommended by your vet, even if they seem fine. Quarantine infested cats from healthy ones for the first few days if possible, but at a minimum, apply treatment to all cats on the same day. This prevents a cycle where one treated cat gets reinfested by an untreated housemate. Regular brushing also helps you spot any returning lice early and keeps the coat healthy.
“Lice are not a reflection of your cat’s cleanliness, they are simply a pest that any cat can pick up. Consistent combing and cleaning will send them packing.”
6. Monitor for Secondary Skin Issues
Constant scratching from lice can lead to raw skin, scabs, or bacterial infections. If you notice red, oozing, or crusty patches, your cat may need a vet-prescribed antibiotic or anti-itch medication. Lice themselves do not cause serious disease, but the damage from scratching can. Keep an eye on your cat’s appetite and energy levels. If they seem lethargic or stop eating, see your vet. Also, be aware that cats with underlying allergies may scratch more intensely, making the lice problem worse. If your cat has a history of sneezing or skin reactions, check our guide on why your allergic cat sneezes so much to help distinguish allergy symptoms from lice irritation. In rare cases, severe infestations in very young or elderly cats can cause anemia, so keep a close watch.
7. Prevent Future Infestations
Once the lice are gone, keep them away. Avoid sharing grooming tools, bedding, or carriers between cats from different households. If you bring a new cat home, quarantine them for at least a week and check for lice before introducing them to your resident cats. Regularly wash your cat’s bedding and vacuum their favorite lounging spots. A healthy coat and good nutrition also support your cat’s natural defenses. If your cat has food sensitivities that affect their skin, you might explore a hypoallergenic cat diet homemade food to strengthen their overall health. Lice are a nuisance, but with a consistent routine, you can keep your cat itch-free and comfortable.
