Oliver

Say hello to Oliver... Oliver T. Kitty.(The T. stands for The.)  Oliver lives with my son and daughter-in-law as well as with Copper and Chewy.

Living with these two happy, happy dogs can get a little much for this kitty, so he needed his own little private get away.  My daughter-in-law got creative with a piece of furniture and built him condo.  Only he can fit in the door she cut on the side. His food is in there, and no one else can get in to eat it.  She says sometimes he goes in and just hangs out.  The dogs can only look in the door and wish they could pester him. 
She cut another door leading to his bathroom.  He can go on into his litter box, and the dogs can't get into that either.   On the shelf above his living/dining space is his pantry where she stores his cat supplies.

This is what you'd see if you walked into their den.

This is what you'd see if you looked at the side of it.

This is what it looks like when she opens the doors.

I think it's genius!
