I believe that, should I/we get to a lovely hereafter, we will learn much. Including that: where there is love, whether from our fellow humans, or from our pets, we will find that they are there also.
Recently, I have come to believe that love is an essential force of the universe, and it can never be extinguished. As witness to that, I frequently pat the handsome little tin where reside the ashes of my favorite kitty, Smokey, gone now nearly 15 years. (He had been a stray with a previously broken shoulder when he arrived meowing at our doorstep. And for 13 years he justified the highest kindness that could be bestowed upon him, and he upon us.)
I send my sympathies; but moreover, great hope that there is no permanent loss of such blessed camaraderie.
