Of all the animal stairs that we know, we can only say: Dear Manufacturer, think before you build. The human depth of the steps is scrap for animals! As SPCA say: Is it finally the anatomy of animals to, makes the steps lower and lower. These stairs are highly praised for animals with intervertebral disc degeneration, which should not jump. Yet it is precisely these animals should even no STAIRS GO! Dogs with long back and short legs are ideal for back problems as spondylosis, if possible, go no stairs and do not jump. Then offer those stairs just for pre-damaged animals only confuses the consumer. For other small dogs and cats baby up the stairs can be used, but there are better, such as ramps. This staircase therefore we give two stars because it is at least stable and paws safe, non-slip cover has. Baby cats love to play it and then not so easy scratching the sofas while trying fed up long.
