If your cat prefers to scratch low, e.g. the lounge carpet, then a horizontal scratcher that remains flat on the floor will be your best option. If he or she, however, prefers to scratch something higher up, a vertical scratcher will do the trick. In this case look for a stand-alone, wall-mounted or hanging model.
What are the benefits of a horizontal scratching post? These are placed flat on the floor, and sometimes have a fairly low ridge. They are often round or rectangular but could be any other shape. It might be possible to attach another small scratcher or toys to one end.
A horizontal scratcher provides your cat with good shoulder and back exercise. This movement has another benefit: it resembles the actions of a wild cat marking its territory in nature.
What are the benefits of vertical scratchers? This type of cat scratchercan consist of a stand-alone post, but one also gets those that can hang from a doorknob or have to be mounted to a wall. All of the above enables your cat to get a really good stretch and to fully extend his or her arms out and up. Another benefit is that when they pull downward from this position old claws are released. Make sure you buy a scratcher that is tall enough for your cat to fully extend his paws, arms and claws.
Take note that this type of scratcher has to be somewhat sturdier, so expect to pay more than for a horizontal scratcher.
