Complaints about dogs and cats running loose in the neighborhood and owners walking dogs without cleaning up after them is a never ending complaint. State and County laws state that dogs must be licensed, leashed, and cleaned-up after, and under control at all times. Cat owners should be aware that free-roaming cats are at risk. Cats are subject to poison by chemicals used on lawns, by rodent bait, and by antifreeze leaking from cars. They may be tortured or killed by a sick individual, or stolen and sold to research laboratories. Studies have documented the serious impact of free-roaming cats on the populations of birds and small mammals.
