The presence of pets onboard must be communicated beforehand so proper preparations can be made. The safety of both guests and crew members is paramount. So, boundaries must be established between human and animal passengers during the voyage. Pet owners should inform themselves thoroughly about local ordinances concerning leash laws and other requirements for containing animals while ashore. Adequate cleanup equipment must also be taken to ensure no trace remains from having had an animal onboard once disembarked from the vessel at the end of the journey.
