I am trying to understand the behaviour of a stray cat which daily comes outside our gate and meows. My friend and I give her milk. She then drinks it and starts moving in between our legs with tail vertically up straight. When I try to move back, she comes toward me. When I try to touch her, she starts looking at my hand. Although she is very small, I am afraid of her nails. But when she is drinking milk, I can touch her on her head, until she is drinking. I really want to pick her up :3
My question is: what does the cat's behaviour mean? Is she getting friendly and wants attention or want me not to touch her?
