What Causes Lice In Cats?

Lice in common house cats is pretty rare, thankfully. The cats who suffer from lice the most are ones in poor condition and homeless cats, such as ferals.

Two main things cause lice in cats:

  • Lack of cleanliness
  • Exposure to other cats

Prevention Of Lice In Cats

Cats get lice from other cats. There is more chance of them contracting lice if they are not kept groomed and clean.

Steps you can take to prevent your cat from getting lice

Keep your cat indoors

There is no doubt, a cat who is exposed to the elements of the great outdoors has a much higher risk of getting lice and other parasites. There are many other dangers that come with being an outdoor cat such as ingesting poisonous chemicals, coming into contact with a wild animal or mean-spirited person, getting fleas and on and on.

If your cat wants to spend time outside, consider building him a catio. There are DIY ones you can create for less than $100.

Some cats will walk on a leash and harness. This is a great alternative to roaming free, if you can get your cat to agree.

Limit Exposure to Other Cats

Reduce exposure to other cats unless you are sure they do not have lice. This is especially important for foster parents and rescues. A guest in your home can be a wonderful way to help cats in need, but be sure he is all checked out and parasite free before he stays.

Flea and Tick Treatment

If your cat is outside, even in your yard, catio or cat enclosure, using flea and tick treatment is a good way to prevent lice. The best ones will be recommended by your Vet and safe for both your cats and you.

Collars are one option. Another option is ointment you put directly on your feline, right between the shoulders on her back.

Step-by-Step Directions on Preventing Lice in Your Cat

  1. Regularly Inspect Your Cat: Begin by routinely inspecting your cats for any signs of lice or infestation. Check their fur, especially around the neck, ears, and tail regions, where lice tend to congregate.
  2. Keep Your Cat Clean: Regular grooming is essential to prevent lice in cats. Brush your cat’s fur to remove dirt, debris, and lice eggs (nits) that might be present.
  3. Use Flea Prevention Products: Invest in reputable flea prevention products for your cat, as they often provide protection against lice as well. These products may include spot-on treatments, collars, or oral medications. Consult your veterinarian to determine the most suitable option for your cat.
  4. Isolate Infected Cats: If you have multiple cats, isolate any cat found with lice to prevent the infestation from spreading. Separate the infected cat until they are treated and lice-free.
  5. Consult Your Veterinarian: If you suspect or confirm a lice infestation, consult your veterinarian for a proper diagnosis and treatment plan. Do not attempt to treat lice in cats on your own without professional guidance.
  6. Follow Veterinary Recommendations: If your veterinarian confirms a lice infestation, follow their prescribed treatment plan precisely. Treatment may involve topical medications, shampoos, or other specific remedies to kill lice and lice eggs.
  7. Clean the Environment: Prevent reinfestation by thoroughly cleaning your cat’s living environment. Wash your cat’s bedding, toys, and any other items they frequently come into contact with. Vacuum carpets and upholstery to remove any lice or eggs that may have fallen off your cat.
  8. Regularly Treat All Cats: Even if only one cat in your household is infested with lice, it’s essential to treat all cats to prevent the spread of lice among them.
  9. Monitor for Recurrence: Keep a close eye on your cats after treatment to ensure the lice infestation does not return. Continue routine grooming and use flea prevention products as recommended by your veterinarian.
  10. Educate Yourself: Learn about the life cycle of lice and their habits in order to better prevent future infestations. Knowledge is key to maintaining your cat’s lice-free status.

Remember that preventing lice in cats is an ongoing process that requires vigilance and proper care. Regular inspections, grooming, and consulting with your veterinarian are essential steps to maintain a lice-free environment for your feline companions.
