More progress (?) in feline-dog relations.
The Dog is standing in the bathroom, looking at me. The Cat walks up behind her, covertly, and starts sniffing the Dog's butt. Dog turns around to look at what Cat is doing. Cat growls, as if to say, "don't look at me while I'm trying to sniff your butt." Dog turns back around to look at me. One could almost see the Dog shrug.
Cat finishes "investigation" and walks away.
