I didn't think Tobie would use them either because he seemed to enjoy leaping off of everything but now he uses them every time he gets off of the bed. As soon as I got the stairs, I used treats to have him go up and down a bunch of times...by the end of the day he was using them on his own. At first he was a little unsteady on them but now he flies up and down. Petsmart (and I'm sure other places) will let you return them if she doesn't use them so I would give stairs a try.
