This is exactly what we needed for Nugget.  She needed a "safe haven" from one of our little dogs. We have tried for years, but she and one of our little shih tzus absolutely REFUSE to be kind to one another.  This will give Nuggie plenty of space to rest while looking down from her cozy spaces. Miss Emi has no idea there is an entrance to the cat box on the lower level, and we are very fortunate that neither of the dogs have a desire to eat from the cat box!!!  I did make a couple of modifications.  Instead of the slanted food and water dish, I closed off the opening where the board slants up and used a non-skid plastic to set her water and food dishes.  I found it much more convenient.
