This idea works equally well for small dogs and oversized cats (we know quite a few tubby tabbies). And we'd recommend you hit up the Rose Bowl Flea Market or Fairfax Flea Market for a well worn vintage suitcase that has a bit of character for your whiskered character. We have a few scraps pieces of memory foam which we could double up to create the mattress part of this bed, but perhaps natural latex would be preferable.
