if you need steps just becuase your pet is small these are fine. if you need them becuase your pt has mobility problems know that htey are very step and narrow and theres not much room for the animal to get up one step at a time. Its really i feel al design fail. They are made fine, sturdy, so no complaints there,,, but my cat goes one step at a time and couldnt use these. we are going to  give these away and just build some with wider shallower steps
