These little cats came with Petite Catwalk Kitties. As I bought a couple of Chases, I got two similar cats and decided to use them as decorations on both sides of the door of the Birchfield house.
Here I have attached them into a piece of wood using mirror mounting tape to make painting easier. As the tape is fairly thick, the cats do not touch the base and that ensures the paint won't make them stick to it.
The next stage is painting the cats with a "stone" color. Anything from off-white to beige and even some darker shades are suitable for this. I used solvent-based paints as the cats are made of hard plastic and can take it.
The final stage is blackwashing. Take some white spirit (or turpentine) and add a drop or two of black paint in it (if you use water-soluble paints, use water instead). The amount of paint depends on how much of it you want on the surface of the statue, that is, how old and dirty the statue should look like. This takes some experimenting to get it right. Then just apply a coat of the mixture to the statue and let it dry.
