Cluin... cats eat rats. Now... well trained and cared for cats do no shit on other peoples' property nor piss on their laundry. Nor do they fuck in your trees.

Unfortunately, the law does not require people to be trained for ownership of cats OR dogs. Such would never eliminate all problems, but would go a long way to keeping problems to a minimum. From there, I am sure the odd problem could be managed.

Most problem cats are wild. Fact is, you ain't gonna see them... on accounta they are wild.

I did have a cat once who was crapping in my neighbours flower bed. Once I was told, it only took me three days to train it not to do so.

The cats are not the problem. Ignorant owners are the problem.
