Here is the culprit.
Cat Tip for the Day =^..^= In-appropriate Scratching & I THINK I Found the Answer
We all love our cats ***BUT*** sometimes they do naughty things. Sierra is the worst for scratching inappropriately. I have purchased many different scratch posts over the years but she prefers our door-frames. We have the wide, wooden frames as our house is quite ancient. So after banging our heads on these frames enough times, I brought into the house a REAL TREE. This tree stands about 7 ft. and is safely tucked into a corner on the main floor. I know, Better Homes and Gardens would gag but what am I to do? This tree is the ticket. The door-frames have been totally ignored and this tree is rapidly disintegrating before our eyes. They all LOVE it. Once this tree is totally used up I will get another one. Some day we have to sell this old house and who wants to buy a house with no door-frames? I am still waiting to see one of these old seniors climb to the top but then that would take energy and why do that when one can sleep. ^..^
