To heaven. The cats love this. It is very tall but does have a safety hook at the top. Our big cat loves the top spot. Every time he is on his way up that tune comes in my head because he really looks like he's climbing the stairway to heaven. Now the littler one she's happy in the little pouches that she fits into just perfectly. Okay sorry for that one. Really this is a great all inclusive spot to stop, sit, or scratch. Definitely would get it again.
