Such a plump cushion to sit on, but best of all the antique mahogany legs that I love to sharpen my claws on. I know she hates it, but I hate that stupid scratching post. Why you may ask, if I know it annoys her, do I continue to cause dissatisfaction by my continual sharpening? To have good claws, a cat must always be at war. Or near enough.
