No person having ownership, custody, possession, or control of any animal shall allow or permit such animal to defecate in or on the public property included within any City park. In the event any animal shall defecate in or on any public property within any City park, the person owning such animal, or the person who at the time has custody or control of such animal, shall cause the product of such defecation to be immediately and completely removed from the City park and shall thereafter cause the same to be properly disposed of outside the City park. No person having ownership, custody, possession or control of any animal shall leave such animal unattended in any City park in any manner which would render such person’s ability to comply with this section impossible or impractical. Nothing in this section is intended (and should not be construed) to alter, amend, or in any manner modify any other ordinance regulating the ownership, possession, or control of any animal.
