According to several studies cats are wreaking havoc on native wildlife. http://www.nytimes.com/2013/01/30/science/that-cuddly-kitty-of-yours-is-a-killer.html?_r=0 According to this article cats kill a median of 2.4 billion birds and 12.3 billion mammals a year, but it is feral cats that pose the biggest problem. Still should pet cats be allowed to roam the neighborhood freely? As far as I know all other types of pets are required to be contained or leashed. The infrastructure is already there to pick up strays and fine their owners. This would also cut back on the number of feral cat colonies and allow us to identify feral cats easier. Some time ago there was a thread that showed two knuckleheads drop kicking a cat. I found that disturbing and I am not proposing any type of inhumane treatment. Cats will act like cats and there is nothing we can do about that. It is the level of responsiblity should we expect from pet owners. So what to you think? If someone has a pet cat should they be required to contain it?
