When I look at it, I sense old dresses and shirts. I wonder if it was made from used fabric like a memory quilt. Do all the fabrics feel the same, or are they different like they came from several sources and are they all cotton?
It was in the 70's that almost everything was polyester or some synthetic. My girls said I killed so many "polys" making clothes that never needed ironing, that I made them an endangered species. :D
Great find! IMHO, if your cat likes it, it has love vibes in it.
