This scratching ball is made in jute rope, glued with foam ball inside.
And the bottom is made of MDF,20mm thick, to insure the stability while cats use it.
Now it is green, but harmless to our pets. Color can be changed as you need. Bottom has two colors for options now, but also can be changed according to your request.
Together with the big scratching ball, there is a small ball installed with elastic band, to give cats more fun to have. It is packed in small box, quite a good gift to your pets and your family.
