Not fair to malign all our species for this.  Most of us have never even owned cats.  I have, but I have never abandoned one.  This is the problem with the 'community' cat nonsense--it's a form of political coercion by 'no-kill' animal welfare extremists who demand we as a 'community' assume 'responsibility' for the plight of abandoned domestic felines simply by virtue of being HUMAN, when we don't even do that for each other!

But the cat-nutters argue we're guilty because we're human and our species has abused and exploited 'da poor widdle tiddeez' for millennia. Therefore we must accept without complaint being exposed, along with our children, to the more than 30 potentially fatal zoonotic diseases carry and be prepared to sacrifice ourselves, our children, and all living things (all of which taken together are less important than the life of a single cat) on the altar of the cat-nutters' monumental, sanctimonious egos.

And by all living things, that includes the cats themselves.
