Perfect for older cats or cats missing a limb.  We have a three legged tabby, Rufus. (We adopted him that way.)  Because he’s missing a hind leg, jumping up and navigating heights  most kitty condos is too hard for him. He gets on our tall bed by using pet stairs, so when I saw this tree with steps, I thought “perfect!”  Once Rufus figured out that there was a tree he could use AND get away from a pesky younger cat, he took to it like a duck to water! We have it positioned by a huge window so he naps daily in the sun when not watching birds and squirrels from his favorite bed on top. One of the best pet products I’ve ever bought and it was easy to assemble.
