Thank you, they seem quite happy in there. They've lived there for 6 years now (hard to believe!), so I guess they used to it. Louie is the only one that ever shows any interest in what's beyond the door. None of the others seems to care.
Wow! That's Awesome! I wish I could afford to make a place like that for my two cats. They could have their own house. ;-) Does this have heating and air? I noticed that it had water. Just curious.
