So sorry your kitty has died, it is never easy, tell us something of what made her special to you. How long was she in your life?
All of my cats lost weight as they got old, Calamity Jane was down to about 7 pounds when she died at a little over 21. She weighed 12 - 13 when she was a young cat (her sister Queen Victoria was 14 - 15 pounds when young and lost a similar amount when she got sick at 17 1/2).
Hi Honey and welcome to the forum.
I am so very sorry for your loss.
Hugs
