What is the cleanest pet to have?

Inquiring minds want to know: when it comes to choosing a pet, what criteria define "the cleanest" option? Are we considering factors such as shedding, odor, ease of grooming, or perhaps the pet's natural inclination to be tidy? Each pet breed or species has its unique set of hygiene requirements, so it begs the question: what pet requires the least amount of maintenance to keep its environment and itself relatively clean? Is it a cat, with its self-grooming abilities, or perhaps a specific breed of dog known for its hypoallergenic coat? Or, could it be a reptile or amphibian that requires minimal upkeep in terms of cleanliness? The search for the cleanest pet is indeed a multifaceted inquiry, and we seek to understand which factors weigh most heavily in determining the ultimate answer.
