What a terrible article. 

Cats do not belong in our ecosystem - any more than pythons belong in the Everglades. 
They are destructive, spread disease, and are the victims of cruel people who re-dump them because of “Life at any cost”.
It’s dangerous to humans too. 
One rabies shot upon neuter does not protect a cat for life. 
Toxoplasmosis can slowly destroy a young mind. 
More and more rabid cats are showing up in colonies. 
Just Google “Rabies in outside cats”. 
TNR does not work. 
It had 30 years to try. 
This outside need to hoard is sad - for the cats, and a danger to our children, wildlife, and immune compromised. 
Seeing your child going through mental changes due to Toxoplasmosis- is not “heartwarming “. 
The time has come to put liability on these irresponsible colony feeders.
