Any law that will cut down on the cat population is A-OK in my book. I'm not just saying that because I hate the horrible creatures.. it's just unnecessary for the animal to not be fixed.
That being said, I agree that there should be some sort of licensing when it comes to owning a pet. People should be educated about various breeds and needs of pets before they purchase an animal.Go to any dog thread here and I'm sure you'll find I've said the same thing. It's not a powerful breeds fault that it killed someone. It's the dumbass owner that didn't know what the hell was going on.

So yeah, like I said.. Down with cats!! errmmm I mean, I think this law is a good thing
