Sometimes one is lost....

Nature is full of abundance.

Her fecundancy  is bountiful, how else to provide for the future?

All beings have one imperative, and that is the biological one, to reproduce.  Within that "special purpose" there is abundance in numbers. 
When a Momma Kitty has her heat she mates as often as she can. in her litter she has insured her ability to procreate with many, often there is a little one that is called the "runt". it is not her choice,  just nature.

Our Paper Bag kitties were so young & so small when first discovered. Even though we fed & pooped them diligently, they began to suckle upon each other, which is not a good thing as it leads to infection plus other problems. But very common.  Despite  all intervention the littlest one, always referred to as "little, little kittie" waned.

Our Dear Kitty Loving Friend took them to bed with her to attend to their needs, before dawn we were awoken to her sobs of finding Little Little Kitty's stiff body & spirit gone.
 In the dark before light we buried her in the fruit grove & gave thanks for her spirit.
Amidst our cries &  sobs, we all hugged in agreement that these kitties would carry on!
One lost, the rest of the litter survives.
