"Animal"

"Animal nuisance"

means any animal other than a dog that makes a noise which emanates from the animal not resulting in contact with another object or structure.

Such extended period of time shall consist of incessant noise for a continuous 30 minutes or more in any 24 hour period, or intermittent noise that accumulates to a total of 60 minutes or more during any 24 hour period. For the purposes of this chapter, a noise is not considered a violation if it is due to actions such as the animal kicking a stall or enclosure, dragging of a chain, rattling of a collar, or if the nails of an animal are scratching or clawing on a door, enclosure or other object. An animal shall not be deemed an "animal nuisance" for purposes of this chapter if, at any time, the animal is creating a noise disturbance, a person is trespassing upon private property in or upon which the animal is situated, or the animal is being teased or provoked.
