All of those are "AWWWWWWWWWW!" quality and just way to cute!! They are so sweet and you can see how close they are.

My RB Sambo was exactly like that. He would mother every kitten brought into the house, even allowing them to nurse on him. It was so sweet to watch. He was extreemly affectionate and just had so much love to give that he wanted kittens to love on.
