Abstract: Myodes rufocanus as an important rodent species in the forest regions of Northeast China, has attracted increasing research attention due to its unique ecological characteristics and potential value as a laboratory animal. However, its solitary nature, high aggressiveness, and specific nutritional requirements pose significant challenges for captive breeding. Based on international rodent welfare standards, this study systematically optimized the housing environment, behavioral management, and breeding strategies for Myodes rufocanus. Experimental result demonstrated that:A mixed bedding system of corncob and wood shavings effectively controlled cage humidity while meeting nesting requirements; Individual housing significantly reduced fight-induced mortality.Dietary enrichment (Chinese cabbage, apple branches) and exercise enrichment markedly decreased stereotypic behaviors. Furthermore, subcutaneous implantation of PIT tags enabled precise individual identification. This study establishes a standardized protocol for the laboratory adaptation of Myodes rufocanus, filling a critical gap in welfare research for voles of the Myodes genus.
