What might cause rust coloration in certain rabbit breeds?

The presence of rust coloration in certain rabbit breeds is often a result of environmental factors, particularly poor hygiene. When rabbits live in dirty environments, the accumulation of waste, dirt, or other contaminants can lead to staining of their fur. Additionally, dead hair can trap particles and moisture, further exacerbating the issue. This rust coloration can appear more prominent in certain breeds that are prone to lighter coat colors or have a specific texture that shows discoloration more easily. Maintaining a clean living space and regular grooming helps prevent these unwanted color changes in rabbits' fur.
