I have a ~4 years old male ginger tabby cat.
I adopted the cat about 2 years ago and have no idea where and how he was brought up. He was found in the street, according to the shelter.
Whenever I wake up, he quickly jumps on my chest and presses his forehead under my chin and starts purring with a low voice while I caress him.
This ritual goes on for about 10 minutes and always ends up with him yawning and leaving my chest.
I'm wondering how common is this behavior, and what does it signify?
