Can Cats Catch Human Diseases? The Surprising Facts

Cats aren’t just pets—they’re part of the family.

They’re our snuggly companions who share our homes and brighten our lives.

But as much as we enjoy their company, many cat owners wonder: Can my cat catch my cold or flu? And on the flip side, could my cat pass illnesses to me?

Let’s explore the answers to these important questions.

Understanding Zoonoses

Zoonoses are diseases that can pass between animals and humans.

They can be caused by bacteria, viruses, fungi, or parasites.

According to the World Health Organization (WHO), more than 60% of all infectious diseases in humans come from animals.

That said, not every disease can be shared between humans and cats.

Some illnesses are species-specific, meaning they only affect one species.

While certain pathogens can move between cats and humans, many others can’t.

Understanding the difference is key to keeping both you and your cat healthy.

Can Cats Catch Our Illnesses?

The short answer is: it depends.

Most human illnesses, like the common cold or flu, don’t affect cats.

However, there are a few exceptions where certain diseases can pass from humans to cats.

Diseases cats might catch from humans

Influenza (Flu)

Cats can catch certain strains of the flu, including H1N1 (swine flu).

During the 2009 H1N1 outbreak, cases of infected cats were reported, and the virus was believed to have spread from sick humans.

Tuberculosis (TB)

Although rare, there are cases where cats have contracted TB from humans, particularly in areas with a high prevalence of the disease.

COVID-19

Research during the COVID-19 pandemic revealed that cats can catch SARS-CoV-2, the virus that causes COVID-19.

A 2020 study published in Nature showed that cats could become infected and even transmit the virus to other cats.

However, there’s no evidence that cats can pass the virus back to humans.

Why cats are usually safe from human illnesses

Most human illnesses don’t pose a risk to cats because the pathogens are adapted to human biology and can’t survive or reproduce effectively in a cat’s body.

Additionally, cats’ immune systems are different from ours, making them resistant to many human-specific diseases.

While the risk of passing illnesses to your cat is generally low, it’s always a good idea to practice good hygiene, especially if you’re feeling under the weather.

If you’re ever concerned, consult your veterinarian for advice.

Diseases Transferable from Cats to Humans

While cats bring joy and companionship to our lives, they can occasionally carry diseases that are harmful to humans.

Understanding these risks can help keep everyone safe and healthy.

Toxoplasmosis

This disease is caused by a parasite called Toxoplasma gondii, which is often spread through contact with infected cat feces.

Most people experience mild or no symptoms, but it can be dangerous for pregnant women and individuals with weakened immune systems.

Cat scratch disease (CSD)

CSD is a bacterial infection caused by Bartonella henselae.

It can occur if an infected cat scratches or bites you.

Symptoms include fever, fatigue, and swollen lymph nodes.

While usually mild, it can sometimes require medical attention.

Ringworm

Despite the name, ringworm isn’t a worm—it’s a fungal infection. It can cause red, itchy, ring-shaped patches on the skin.

Cats, especially kittens, are common carriers of this fungus.

Salmonella

Cats can carry Salmonella bacteria, particularly if they’ve eaten raw or undercooked meat.

Humans can become infected by handling contaminated litter boxes, cat food, or even the cats themselves.

Tips on Maintaining Good Hygiene Practices

Whether you’re concerned about your cat catching something from you or vice versa, practicing good hygiene is the best way to protect both of you.

Here are some simple steps to help minimize the risks:

Wash your hands regularly

Be sure to wash your hands thoroughly, especially after cleaning the litter box, handling your cat’s food, or playing with them.

This helps prevent the spread of germs and keeps both you and your cat healthy.

Practice safe litter box hygiene

Scoop the litter box daily and clean it regularly with soap and water.

You might want to wear gloves while cleaning to reduce the risk of coming into contact with harmful bacteria.

Keep your cat indoors

Indoor cats are less likely to come into contact with other animals or environments that could carry diseases.

Keeping them indoors helps protect them from illnesses.

Vaccinate and deworm regularly

Regular visits to the vet ensure your cat is up-to-date on vaccines and parasite prevention.

This helps keep them healthy and reduces the risk of passing on illnesses.

Avoid raw diets

Feeding your cat raw or undercooked food can increase the risk of them carrying harmful bacteria like salmonella or E. coli.

Stick to properly prepared food to keep them safe from these risks.

Final Thoughts

While the idea of cats and humans sharing illnesses can sound alarming, the reality is that such cases are rare.

Most of the diseases cats can contract or transmit are preventable with proper care, hygiene, and regular veterinary checkups.

The bond between humans and cats is a testament to our ability to coexist and thrive together.

By staying informed and taking simple precautions, you can ensure a happy, healthy life for both you and your feline friend.
