I'm not sure why she looks so alarmed in this picture - Melly wasn't anywhere in sight at the time. Oh well.
As I was putting together this post, Scarlett puked in the hallway*, then slunk away attempting to look innocent. Melly came over and sniffed at the puddle, then attempted to bury it by pawing at the floor all around it. She then sat down a few inches away and stared at me until I'd cleaned it up. She gave the area a thorough sniffing before walking away.
*I think she just gobbled down her food too fast, but I'll be giving her some petramalt just in case.
