There are plenty of communities that have laws requiring a cat to be leashed or restrained in some manner if outside. I don't know what the laws in this community are. I doubt if the snake owner was in violation of any law if the snake was on his property, at least if this occurred within a fenced yard. As someone pointed out if this was a dog rather than a snake it wouldn't even be news. Cats and dogs that are allowed to roam free off of your property often meet an early demise. If you let your cat roam free you have to be ready to accept that It could be shot, hit by a car,poisoned, killed by an animal or any number of things. If you can't handle that you should keep it inside.
