I'd say mine have a stronger bond with me than each other. They play with each other and chase each other around but they can get scrappy too with each other. They will always want to be just with me though. When we are sleeping one is on one side of me and the other one is on the other side. I keep them separated when I leave as they tend to fight. I don't think they would rather spend time with each other over me though. In fact, I am giving Sadie more attention then Maggie scraps at her, she's a little selfish sometimes.
