Purchased several months and had not assembled because I had to find a place to put it. I was very pleased after it was assembled and then decided to put it in my living room about two weeks ago. After getting every thing in place waited for my two cats to check it out. That did not happen so waited to see if they would begin to display some interest, as of this date, there has been no interest. These are two adult cats, ages 6 and 13, who really enjoy interacting with the adults in the household. The condo seems sturdy with ample room for them to play, so I don't understand what the problem is because we have placed them on it, played with them and tried to introduce the condo in their play, have also tried to lure them to it with food. The only thing I have not mentioned is that they are very spoiled. I may keep the nice new condo and get a couple of new cats. lol. We will keep working on it!
