I have repaired and restored a few cat statues this past year.
One was a statue given to me by a friend years ago upon the death of one of our cats. It has been in our garden for 10 years slowly crumbling away. I finally decided to make some paper clay to rebuild the parts that had crumbled and then repainted it to resembled the cat that we had lost. I found a great water sealant to keep both the paint and paper clay sealed tight against the rain and snow. It looks great and our memorial statue of our cat "Pyro" is back in the garden again.
The second job was on an old stone cat from my grandfathers house that had long since worn away its paint. I didn't have to do any real repair so I just sanded it down, painted it and sealed it for use in the garden. It has been returned to my parents house where it sits leaning over their pond.
