Sometimes I wish they weren't - these are our homemade pet steps for Princess Brynn since my bed is so high up it is hard for her little legs to get up that high... then she whines about it.
So I got her to go up them once, with a treat of course, but now she looks at me like "pft dream on" *shakes head* try to make life easy for her and she won't just go up them... instead she'd rather make a face and noises at me as if I should move the stairs out of her way.
