I know, I can make some small things up seemingly from whole cloth. Just details of no consequence of course. But not this. This I couldn't have made up.
Setting here getting work done. Dog asleep somewhere. Cat hovering about. Finish reading a draft of something that deserves to be shredded. Lean over toward the shredder and Lincoln (the cat) hops up on top. Sitting there purring as my hand draws near knowing she'll get a moment of attention.
The magically disappearing paper gets her attention. She leans down to watch and consider. Apparently a long whisker gets caught. Because all the sudden she's screaming and meowing and yelling and making other weird noises previously unheard even in this household. Her back end is spinning out. She's power sliding from one side of the shredded to the other and then pulling the diabolical machine down with her. Somewhere in this process cat poo and pee ejecta were spread in a fan pattern with back paw sized skid marks streaming it about.
In short enough order the cat was freed and the offending machine was vanquished. Cat sitting about 20 feet away trying look as victorious and dignified as one can while suffering the indignity of lopsided facial hair. After the ten minutes or so it took to quit laughing I did get the mess cleaned up. Cat hasn't been close since.
