My cat? I had to push her out of the way to get the old stuff into the bowl. :)
And also - if you had a choice of two boxes on the floor in which to sit (and if you're a cat, not sitting in a box is just not an option), and one of the boxes was far too small for your fluffy ass and the other was just the right size to contain a cat, which one would you choose?
She was originally in the smaller box, and after she shifted position for the third time in as many minutes, and tried to lie sideways in the box, I took pity on her and fetched the cat-sized box. She got into it for a few minutes, but shortly thereafter abandoned it for the old box, as you see above.
Just to show you that's not fur that's overflowing, that's solid cat:
