For many cat owners, sharing a bed with their furry companion feels comforting, safe—even therapeutic. But while the risks are generally low, there is one illness that health experts often mention when discussing close contact with cats:
Toxoplasmosis
This condition is caused by a microscopic parasite called Toxoplasma gondii, which can be carried by cats—especially those that go outdoors or hunt prey.
How does it spread?
Contrary to popular belief, you don’t usually get it just from your cat sleeping next to you. The parasite is most commonly transmitted through:
- Contact with infected cat feces (like cleaning a litter box)
- Touching contaminated surfaces and then your mouth
- Eating undercooked meat or unwashed produce
That said, close contact—like sleeping together—can slightly increase exposure risk if hygiene isn’t maintained.
Why is it considered serious?
For most healthy adults, toxoplasmosis often causes mild symptoms or none at all. But in certain cases, it can be more dangerous:
- Pregnant women: It can affect the unborn baby and lead to serious complications
- People with weakened immune systems: It may cause severe infections affecting the brain or eyes
Symptoms, when they occur, may include:
- Flu-like fatigue
- Muscle aches
- Swollen lymph nodes
Should you stop sleeping with your cat?
Not necessarily. The risk is very low if you follow basic hygiene practices:
- Wash your hands after cleaning the litter box
- Keep your cat’s litter box clean daily
- Avoid letting your cat walk on food surfaces
- Keep your cat indoors to reduce exposure to infected prey
Other minor risks to consider
Sleeping with pets can also expose you to:
- Fleas or mites
- Allergens (which may disrupt sleep or breathing)
- Bacteria from fur or paws
The bottom line
Toxoplasmosis sounds scary, but it’s rare and preventable. With simple precautions, you can safely enjoy the comfort of your cat without putting your health at risk.
So yes—there is a potential illness linked to sleeping with cats…
But for most people, the benefits of that warm, purring companion far outweigh the risks.
