Jester...A number of the arrowsmiths I know use what is called a Massey finish (after Jay Massey) on wood arrows.
Take one part DEVCON 2 Ton epoxy and three parts acetone, mix, rub on handle with cloth (you only get one wipe here as it gets tacky QUICK)
Two coats of that will make a finish that the cat can't scratch. Works on wood, bone, antler, etc.
Store in a baby food jar, turned upside down after lid is tight, and it will keep for months. I have found wood arrows that spent several years outside with no ill effects after this treatment. Tough finish. Will stick over most oil based finish also (like Watco...nothing else sticks to Watco!)
