Great picture!  I actually have a cat looking EXACTLY like that and he exactly sits on top of this stairs just like so!  

Yes, cats love this.  It's not easy for him to walk up and down the steps than having to jump!  He loves it.  It is a must have for lazy cats... and for older cats.  Older cats don't like to strain too much.  Give them loves!  

Pros: Good sturdy construction.  Fuzzy.  Stable.  Usable.  Good heights.
Cons: Pre defined heights.  Measure to make sure everything fits.
