Cashmere Twinset Does Anyone Know How To Remove Urine Odor From A Cashmere Sweater?

Does anyone know how to remove urine odor from a cashmere sweater? - cashmere twinset

My neighbor gave me a great cashmere TwinSet he took of the art "50" is of good quality cashmere and has only two small holes. The problem is that the jerseys were stored in his attic for some time and a very strong smell of animal urine on them.

I dry cleaned and the smell has dissipated somewhat, but it is nonetheless remarkable. I hate to get rid of the beautiful game, but can, if you can not get rid of the smell. (They are completely useless at this point.) All the suggestions we are grateful.
