My cat loves to look out the window but is now 15 years old and a window perch would not be accessible to him so this product offered him a way to get to the window and have a place to look out. He loves it. The steps are close enough for his old bones to manuver but I wish the top step was a bit wider so he could curl up on. The only complaint I have is there are screws on the bottom that scratch the floor when moving the step. I have learned to pick it up when I need to move it.  Other than that it is a great product.
