Cat tree - a sisal post

Cats must be allowed unlimited scratching, because they sharpen claws in this way and it is their natural need. Having a sisal post the cat will have the opportunity to scratch - otherwise it will direct its attention to the furniture or carpets in your apartment.

The scratcher consists of a round sisal base, sisal post, colorful mouse heads, and balls on a string, which further encourage fun.
