It can certainly be challenging to figure out which specific cat is the one we lost or the one that ended up rezzing as a white cat on the dock while trying to retrieve it from the online cattery. I retrieve cats from the cattery to inworld and vice versa daily and the only times i have lost kittens recently have been during this process.
Considering the "dud" that rezzes on the dock contains no info whatsoever of which cat it was supposed to be, the comparison between the "stock" in world and what's listed on pedigree can take a long time (and leaves me with a lot of eye strain as well).
I support this request fully, as it might alert us of the lost of a cat even before we notice it in world. Also extremely helpful for us with cats at various locations on the grid.
