Shortly after the picture, Izzy closed here eyes and happily slept.
Also Kaylee likes to watch WoW and TV, which nate and Izzy haven't even noticed.
EDIT: after they'd both slept a good deal, Izzy apporoached KAylee and gave a nose sniff, touching nosees. Then kaylee approached Izzy, same thing. Then there was a paw and a hiss, but this is so encouraging.
