This cat is made from cold porcelain. I am using the marble here as weight so as to hold the cat figurine upright.
The cat stays upright when rings are placed around its tail. I am using a regular size, plain white marble here but you can try it out with any color or designed marble that you have and it will still turn out fine.

I used a light pink color nail varnish and Sharpie pens for this Cat Ring Holder
