This is a cat necessity when dealing with older, injured or arthritic cats.  Bud,the old man alpha cat of the house, is 20 years old - no joke!  Bud can easily maneuver these steps.  They are wider and deeper than any weve tried before, and a couple of my little ones (cats) love to perch or sleep on the steps. I wish Id had this when Lester, my first love, was still with us!  Wayfair, thank you so much!
