Why People Share Their Bed with Cats

Across countries like the U.S., Argentina, Colombia, Mexico, and others, it’s common for pet owners to welcome their cats into their beds. There are several psychological benefits to this:

• Cats offer emotional comfort and ease anxiety
• Their presence creates a feeling of security, especially for those who live alone
• The companionship strengthens the emotional bond between the pet and the owner
• Oxytocin, the “love hormone,” is released during these close moments, elevating mood

However, while these emotional perks are real, it’s important to consider the less pleasant side of the arrangement.

Health Hazards You Might Overlook

Even the cleanest cats can carry organisms and allergens that pose a risk to human health.

Zoonotic infections: Cats can transmit illnesses such as Cat Scratch Disease (which can cause fatigue and fever), Toxoplasmosis (especially risky for pregnant women and immunocompromised individuals), fungal infections like Ringworm, and parasitic infections such as hookworms or tapeworms.

Parasites: Fleas and ticks may find their way into your bedding, even from cats treated with preventative products, potentially triggering infestations or diseases like rickettsiosis.

Allergens: Cats produce a protein called Fel D1 found in their saliva and skin, which can lead to sneezing, coughing, congestion, and even asthma in both allergic and previously non-allergic individuals.

Interrupted Sleep

Despite their calm demeanor, cats are naturally nocturnal and often become playful or restless at night.

If your pet is walking across your bed, pawing at your face, or purring loudly in the early hours, your sleep quality is likely to suffer. Interrupted rest can lead to daytime tiredness, mood swings, and lower productivity.

Unexpected Financial Costs

Dealing with cat-related infections like toxoplasmosis can result in high medical bills, especially in countries like the U.S., where healthcare is expensive.

Even in places with more affordable treatment, costs from vet visits, parasite control, and frequent cleaning products can accumulate.

Tips for Safe Co-Sleeping

You don’t have to banish your cat from your bedroom. Here are some precautions to keep both of you safe:

• Vet care: Schedule checkups twice a year, maintain vaccinations, and ensure regular deworming.
• Clean linens: Use allergen-reducing sheets, wash them weekly in hot water, and vacuum your mattress every two weeks.
• Grooming: Brush your cat regularly, clean their paws—especially if they go outside—and bathe them when needed.
• Clean environment: Use air purifiers, keep windows open for ventilation, and minimize allergen-trapping materials like carpets.
• Offer alternatives: Create a cozy bed near yours to give them their own sleep space while keeping them close.

Regional Differences

While the types of health risks remain fairly consistent worldwide, the likelihood of exposure varies. In places like the U.S., access to vet care and parasite prevention reduces risk.

However, in parts of Latin America with warmer climates and more outdoor cats, the chances of disease transmission are higher.

Final Thoughts

Letting your cat share your bed can be a deeply comforting experience—but it isn’t without potential issues. With some mindful practices, you can continue this bonding ritual while safeguarding your health and well-being.

After all, true love for your pet means keeping both of you safe, even when cuddled up together at night.
