Understanding Cat Lice

two cats outdoors - the main location where they get infested with lice.

Cats can become infested by lice, just like dogs can. 

It's relatively uncommon for cats to get infested by lice because indoor cats don't come into contact with many risk factors. Lice are species-specific and cats can only get lice from other infested cats. 

Dogs cannot give cats lice, and cats cannot give dogs lice. The same goes for humans. Still, outdoor cats can become infested when they come into contact with cats in the neighborhood. 

This article discusses the symptoms, treatment, and prevention of lice on cats. If your cat is showing lice-like symptoms, but they haven't been exposed, consider the following causes of itchy, irritated skin:

Symptoms of Cat Lice Infestation

Lice infestations in cats may not be as commonplace as some other pest problems, but when they do occur, they come with a distinctive set of symptoms that should not be ignored.

The hallmark symptom of lice infestation in cats is relentless itching. If you notice your feline friend scratching themselves incessantly, particularly around the neck, head, and ears, it's a glaring signal. 

Lice-induced itching and discomfort often lead to a ragged and unkempt appearance in your cat's coat. They may excessively groom, bite, and scratch themselves resulting in hair loss and a generally disheveled appearance.

These symptoms of lice can make your cat feel constantly on edge, and they might have trouble settling down or finding their usual sense of calm.

How to Treat a Cat with Lice

So what are the strategies and methods that can help you combat these pesky intruders?

Medications for Lice Infestation

Medication may come in the form of sprays, shampoos, or dips. It's crucial to consult your veterinarian for guidance on selecting the most appropriate product for your cat's specific condition.

Prolonged Treatment Duration

Lice infestations are persistent, and it's essential to continue treatment for an extended period. This ensures that you eliminate the entire life cycle of lice, including both adult lice and their eggs.

Consider Shaving in Severe Cases

In severe lice infestations, shaving helps remove lice and their eggs, allowing for more effective treatment. Consult your veterinarian before opting for this approach.

How to Prevent Your Cat from Getting Lice

Let's explore the strategies and home care tips that can help you keep lice at bay and ensure your cat's continued well-being.

Monthly Flea Preventatives

Believe it or not, monthly flea preventatives can also serve as a shield against lice infestations. Consult your veterinarian to select the most suitable preventive treatment for your cat's needs.

Maintaining a Clean Environment

A clean living environment is the first line of defense against lice. Regularly clean and disinfect your cat's living space, including their bedding, toys, and resting areas. 

Regular Veterinary Care
Regular check-ups with your veterinarian allow for early detection of any signs or symptoms of infestation, ensuring timely intervention if needed.

Vigilant Grooming and Hygiene
 
Brush your cat's fur to remove dirt and debris, which can attract lice. Additionally, maintain good overall hygiene for your cat, including oral care and keeping their fur clean.

Lice Transmission Between Cats and Humans

The good news is that lice don't partake in cross-species adventures. In other words, humans can't get lice from cats, and cats can't get lice from humans. Lice are what we call species-specific parasites. They've adapted to thrive on a particular species, and they don't venture beyond those boundaries.

Conclusion 

Cats can contract lice from contact with other infested cats. Fortunately, lice on cats can't spread to dogs, humans, or other species. 

Contact your veterinarian if you suspect that your cat has lice. In the mean time, consider using a soothing topical balm to support their skin issues as they recover.
