For many cat owners, letting their furry friend curl up next to them at night is a sign of affection, trust, and comfort.
The soft purr, the warm body at your feet—it’s hard to resist. But this seemingly harmless bedtime routine may come with hidden risks to your health, sleep quality, and even your wallet.
Why People Sleep with Their Cats
It’s common across the U.S., Mexico, Colombia, Argentina, and elsewhere for people to sleep with their cats. The benefits are real:
- Reduced anxiety and stress, thanks to the cat’s calming presence
- A sense of safety and companionship, especially when living alone
- Stronger emotional bonds
- Boosted mood from the release of oxytocin, the hormone linked to love and affection
But while the emotional upside is clear, there are potential downsides that deserve attention.
Health Risks You Might Not Expect
Even clean, well-cared-for cats can carry bacteria, parasites, and allergens into your bed.
- Zoonotic diseases: These include Cat Scratch Disease (which can cause fever and fatigue), Toxoplasmosis (dangerous for pregnant women and the immunocompromised), Ringworm (a fungal infection), and intestinal parasites like tapeworms and hookworms.
- Fleas and ticks: Even treated cats can drop flea eggs onto your bedding, sparking infestations or transmitting illnesses like rickettsiosis.
- Allergies: Cats release a protein (Fel D1) in their saliva and skin that can trigger respiratory issues such as sneezing, coughing, congestion, and even asthma over time—even in those without a history of allergies.
