What term describes the discoloration or stains on a rabbit's coat caused by urine, manure, or rust?

The term that accurately describes the discoloration or stains on a rabbit's coat caused by urine, manure, or rust is hutch stains. This term reflects the staining that occurs primarily due to the rabbit's environment, particularly in areas where they spend a significant amount of time, such as their hutch. These stains can affect the appearance of the rabbit's coat and may require proper grooming and maintenance to keep the rabbit clean and healthy.

The other terms do not specifically indicate the source of the stains or their relation to the rabbit's living conditions, which is why hutch stains is the most appropriate term in this context. Fur spots could refer to various types of markings or patterns on the fur, coat blemishes may imply imperfections not specifically associated with staining, and wool discolors generally pertains to fiber or wool qualities rather than the staining of a rabbit's fur from waste or environmental factors.
