Why cats scratch....
Cats' claws continue to grow throughout their lives. Periodically, the base of each nail is encased in a scaly sheath. This scaly sheath causes them discomfort when they retract their claws. Scratching is the cat's natural method of removing the scaly sheath. In nature the cat will scratch trees or logs, but in the house, people want kitty to be selective and not scratch the furniture. Therefore, to save your furniture, Cosmic Cat has provided this safe and effective cat scratcher. To attract your cat, remember to apply a generous amount of Cosmic Catnip (included) to the scratcher.
