If you’re feeding your mice a high-quality, nutritionally complete diet, Jackie, hay may not be necessary. However, it can be a good source of minerals and fiber for your pets. Hay can also provide entertainment, as your pets can burrow through and build nests out of it. To determine if you should provide hay for your mice, you may consider discussing their diet with your veterinarian, who may have additional recommendations based upon their nutritional requirements. If you do choose to give your mice hay, please be sure that it’s high quality and free from mold and dust.
