What Does a Cat’s Behavior of Sleeping Next to Us Reveal?

Happiness for some people may be a warm puppy, but others will swear that true joy comes from sleeping with their cat. There is some controversy about people and pets sharing a bed, but it’s not exactly easy keeping a cat out of your bed — except by his own choice.
LOVE – The simplest explanation is that your kitty loves you. Many cats undoubtedly reciprocate the affection their human partners feel for them, and one of the ways they show it is by cuddling.
PHYSICAL COMFORT – Cats simply love soft, warm places. You are warm and so is your bed, therefore, he likes to sleep close to or even on you.
TOGETHERNESS – Most cats enjoy sleeping together. It may be they remember being kittens, piled together in a warm, fuzzy bunch next to their mother’s bountiful belly. They share warmth and affection with one another, and in the absence of other cats — or even in preference to them — you make a good substitute for a bundling buddy.

MENTAL COMFORT – If your cat is nervous or anxious about something at all, sleeping next to you can make him feel safe. Incidentally, this can work the other way around, also. There is no lullaby at all quite like the purring of a cat — the ultimate in white noise.
OWNERSHIP – Your bed belongs to the cat and he magnanimously allows you to share it. After all, you haven’t thrown him out to establish your rights. He’s marked both you and also the bed with his scent. It’s your kitty who decides when he sleeps and when you do, and he decides when you wake up to feed him. In his mind, that makes him top cat. Remember, dogs have masters, but cats have staff!
