She did ok.
I called our friends about mid way through the trip to check on her. She said she felt bad because Layla seemed to lonely..she would come running as soon as they would come in the door and cried and meowed the whole time they were here. She was so excited to see us when we got back.
The night we got back our friends decided to have barbecue so we went over there. She gave me the saddest look when we walked out the door...but was very exctied when we came back a couple hours later.
The only bad thing was that it was around 80 degrees here for a couple of days while we were gone. Our friend was afraid to open any windows just incase Layla could find a way out. It was pretty hot in here when we got back, but I guess she handled it just fine.
