That's so sad :( :(
My Tiny girl passed just last month (December) and another cat I had to put down due to renal failure in Sept of 2016 (Luna)She was such a gorgeous kitty, calico, I had to give her a separate pillow becsuse she kept stealing mine (yay for kitty butt fur!) and she always slept right beside me.
^^^ That's how they'd all sleep with me, no room to move!! But they always kept me warm in the cold Canadialand winters. That's me under the covers with Luna sitting ON me. :) (l-r: Mr Pudgey, Luna, Miss Tiny)
