It shouldn't happen to a cat. 
Cast off, and never having that Black Beauty ending of a warm lap. 
Trapped, made sore, ( neuter )  stuck with a needle, and tossed right back in the cruel streets. 
These are no animal lovers. 
There is no compassion in this abandonment . 
This is a means to an end for an unfulfilled human need to feed. 
It's not the cats fault. 
But this is blatant cruelty. 
TNR is blatant cruelty.
