What type of fault refers to a muddy belly on an agouti cavy?

The term "muddy belly" in agouti cavies indicates a lack of the sharp, distinct color separation that is characteristic of this color pattern. When cavies exhibit a muddy belly, it implies that the color is not clear and crisp, which can diminish the overall appearance and quality of the animal.

Labeling this as a minor fault means that, while undesirable, it is not severe enough to warrant disqualification from showing, nor does it drastically affect the animal's health or structural integrity. A minor fault might impact a judge's scoring, but it doesn't render the cavy ineligible for competition.

In contrast, major disqualifications would involve more serious issues that could affect the animal's health or well-being, serious defects would imply significant structural or genetic issues, and visual flaws usually refer to superficial issues without implications for health. A muddy belly is thus seen as a solvable issue relative to the overall quality of the cavy's coat, justifying its classification as a minor fault rather than a more serious concern.
