@Zero3D:
I have lost not only my cat, but also both of my grandfathers, and even my father.　Yeah, that was more than a few years ago.
"Passage of Time will fix it" ... is what some older than me said.

Indeed, as a result, Many things have changed in my mind.　Most especially my "view of life and death" ... for better or worse.
"Think Everything I see is a Miracle, Whatever the memory and cross♰ I carry will be" ... is my current answer for myself.

Close your eyes, Listen quietly.　Or have a good dream.　You will see your dog again, someday.
