I am crying with you. While you may never get over the pain of losing your kitty, it does get easier. I promise.
When I lost my Taz I cried my eyes out almost every night for a good month. I thought about him ALL the time (and still do, actually).
Nothing we can say can take away your pain. Just know we are right here with you and know exactly what you are going through.

Hugs to you!

RIP Koko
