Why doesn't a cat let you pet her?
I want to know something about cats. There is this really cute cat who always comes up to my door and I would feed her some milk. She would sit there the whole time, but wouldn't come in nor let me pet her nor let me get closer to her.
She would sit in front of the door and just stare at me but won't let me pet her. The closer I would get, the more she would go back, but come back to the same spot.
Why doesn't a cat let you pet her even though she would sit near you and stare at you?
What is the reason as I'm not aware much of cats' behaviors.
