We ended up being owned by six strays.  They absolutely love this.  Two are still unsure only because they don’t really come into our living room much.  They like their own space in other parts of the house and I know they lived a much different life before  I befriended them and bought them inside to live.  This is the best money I have ever spent to make my kitties happy.   I am on a very fixed income and it was a stretch to buy this..but my cats give me such joy I decided to splurge.
