We own a cat.  He is part of the family.  That said, we have our share feral cats in our neighborhood.  Some of them look quite deformed (probably from inbreeding).   A neighbor had a job awhile back going up on Mauna Kea to rid the area of feral cats as it was desimating the bird population.  Our cat occasionally catches a dove which does not make us too happy.  Of all the animals being put down, I wonder how many of them are stray dogs and feral cats?  Seems like we need to get humans to be more responsible about the dog and cat population.
