Shocking Cat Facts: Unveiling the Truth About Stretching 

I have some semi feral cats and they live outside and they will do this. They will come over and show me their bellies. So I know they love me.

Did you know? Cats evolved to guard humans as Pets 😽

Edit!

Hm... I heard they do this because they've slept so long, their legs have fallen asleept and stretching gets the blood flowing again.

A pointless video: It's obvious why your cat stretches when you come home. They're bored being alone all day and know that they'll soon be getting affection and food.
