Baby and Daisy (orange foot)
These two are sisters (and look a lot like bookends) and though I know they'd be lost without each other, they don't always get along. They're not super affectionate with each other, at least not when I'm around. They do play together and sleep on the bed, but each in her own "territory."
Mostly, this is because Baby is so bossy and can be downright possessive of anyone or any thing she takes a fancy to. Now and then Daisy will give her a good slap upside the head, but overall Baby is the boss and she likes to throw her weight around, little brat that she is.
However, when it comes to food Daisy rules and will, if given the opportunity, steal as much food from Baby's dish as she can. That doesn't happen anymore because I keep their bowls on opposite sides of the room and stand guard. Consequently, Baby has filled out in size and Daisy is no longer overweight.
