Ruby says it looks very comfortable! It reminds me of when Ruby was a little puppy and she fell asleep on the sofa and fell off because her head was hanging like that. She wasn't hurt and got right back up and fell back asleep immediately. But she hasn't been on any furniture in a very long time.
Moose was doing the exact same thing last night, on the back of the chair. I couldn't belive he didn't slide right off. I went to get my camera, and of course, he had to jump down and follow me, so I couldn't get it.
