@_Ederle_ I love that you made a collar for your beautiful gray kitty. I did the same many years ago for my grey kitty. However. PLEASE don’t just tie knot it on. You need to get a breakaway clasp (available at craft stores) or sew a inch or two of elastic where the ends meet. A cat must be able to get out of its collar or it could seriously injure themselves or even die. I’m serious. I know of a cat that choked itself on a collar and nearly died. Give your beautiful kitty a pet and snuggle for me.
