Free roaming cats are subject to so many bad things - getting squashed by cars, eaten by a predator, mauled by dogs, fighting with other free roaming cats, poisoned, and hauled off to animal control when your neighbor gets sick and tired of your cat preying at their bird feeder and crapping in their flower beds. Cats do NOT need to free roam outdoors. They are domestic animals and not wild ones - they have been domesticated for over a thousand years. Mine are perfectly happy in their cat trees, windows, and so on. If you insist on letting your cat out, then build him a catico - many plans and pictures are available online. Indoor only cats live a happy 14 years or more (it is not "imprisoning" them) and free roaming cats live an average of 2-5 years. Yes, there are indoor cats that die early and outdoor cats that live a long time - but these are the averages. So responsible people keep their cats indoors, and responsible people do not let their cats become a nuisance to other neighbors. I love cats - but I am considering getting a trap. A neighborhood cat comes into my yard, tears out any garbage she can find, poops in my flower beds, and chases the birds that I attract with a bird feeder. Your right to a free roaming cat ends when that cat becomes a nuisance.
