Within the purview of this article, a cat shall be considered
a public nuisance if it has no known owner or custodian, or if it
has no known place of care or shelter, or if it habitually trespasses
upon or damages either private or public property or annoys, bites,
scratches or harms any lawful user or occupant thereof.
Any person who owns, keeps or harbors any cat at any place within
the municipality or who permits any cat to enter the corporate limits
of the municipality shall exercise sufficient and proper care of and
control over such animal at all times to prevent the same from becoming
a public nuisance, by allowing his or her cat to habitually trespass
upon or damage either private or public property or by allowing his
or her cat to bite, scratch or harm any person.
