The cat, of course, had to lie down on it when I placed it on the floor to measure out how much it has shrunk during fulling. Obviously it is acceptable as a catplace. (I'd cuddle into that cloth at any moment, too - it really feels wonderful, thick and warm though sturdy.)
Measurements, by the way, changed from 251 cm in length to 235 after washing to 230 after fulling; width shrunk from 52.5 straight off the loom to 48.5 after washing to 43 after fulling. It was relatively gentle fulling, I could have done more - but my sources say "lightly fulled" only.
