I remember years ago when I was young , Smokey the Cat knocked over our Christmastree. we thought that my mother would be upset as along with the tree several oranaments , handed down toher and irrreplaceable ones at that were destroyed. But my mother was more concerned about the cats safety and simply said that it was the nature of a young cat to climb and he certyainly did not mean to do the damage. I have always remembered that night and have kept it in mind when the cats have knocked something over or have done something that I dont like , its in thier nature and thy must be forgiven.
