Why does my cat sleep near the router?

Your cat likely sleeps near or on your router for one primary reason: warmth.

Because routers remain plugged in and active 24/7, they emit a low, constant level of heat. A cat's normal body temperature is higher than a human's (between 101°F and 102.5°F), meaning they actively seek out warm microclimates to conserve energy and stay comfortable.

Other contributing factors include:

• High Vantage Points: Routers are often placed on desks, shelves, or side tables. Cats naturally prefer elevated positions where they feel safe and can survey their territory.
• White Noise: The subtle, nearly silent electromagnetic hum or vibration from the router's power adapter can be comforting to some felines.
• Proximity to You: Routers are usually positioned near home offices, TVs, or living areas where you spend a lot of time. Your cat may simply want to be close to your daily activities.
• Cozy Enclosures: Routers are often tucked into corners, shelves, or cable-heavy alcoves, which can mimic the feeling of a secure, tight-fitting nest.
