Introduction

Cats are cuddly, warm, and comforting companions — so it’s no wonder many people let them share their bed at night. But did you know that sleeping with cats may carry certain health risks? While many of these are minor, there’s one particularly serious illness linked to cats that every pet owner should be aware of. Let’s explore what it is, how risky it really is, and whether it’s worth snuggling your feline friend under the covers.

The Most Serious Illness: Cat Scratch Disease (CSD)

The most significant illness associated with close contact — including sleeping — with cats is Cat Scratch Disease, caused by the bacteria Bartonella henselae.

How it spreads: Cats can carry this bacteria in their saliva or on their claws. Even a small scratch, lick on broken skin, or accidental bite can transmit it.

Symptoms: Swollen lymph nodes, fever, fatigue, and headaches. In rare cases, it can lead to serious complications affecting the eyes, liver, or even the heart.

Who’s at risk: Children, people with weakened immune systems, or those with chronic illnesses are more vulnerable.
