I love the idea of these pet steps.  Just make sure your pet is not over 20 pounds- and always check that the lids of each step are properly attached!  My puppy pulled on one and I didn’t see it was loose and he fell through into the box…he is ok.  They are attractive and easily cleaned with a vacuum or lightly applied carpet cleaner.  The steps are actually a box that hold toys.  I would especially love these for small dogs and cats.
