I wasn’t sure how my 19 year old cat would react to these, he was a little hesitant at first until I showed him what to do (I live in FL with no stairs in my house) and luckily he got it. He seemed so excited to be able to use the stairs to get on my bed with the other cats without having to wait for mommy to pick him up.  He just stopped jumping on the bed about 2 weeks ago, so I think the stairs made him feel like a normal cat again instead of the old man he has become.
