There are coyotes, predatory birds, big cats, etc.
Not in the civilised world there ain't. We ate, domesticated, or otherwise drove those to extinction hundreds or even thousands of years ago.
Most dangerous things around these parts (besides free-roaming cats) are cars, and a good public transport system together with a street and road network built around pedestrians and bikes (and said public transport) will get rid of most of those, too (though the reduction in noise might lead to more birds; nothing is perfect).
