Unlike a lot of guys, I love cats. Had quite a few, along with my dogs.
But the love stops when a cat is in my yard, and its not my cat. Feral cats are a nuisance predator, no worse than coyotes and should be dealt with accordingly.
Subsonic rimfire, do the voodoo you do.
As far as feline domesticus, I know they are a "free spirit" type of animal, so if people love them that much, they better live way out in the country, or keep them inside.
Now, torturing and whatnot, that's going too far. Unless they are Al Qaeda cats, in which case, I guess they can be waterboarded.
This kid needed supervision. Now I suppose he'll get it.
