Hay Manger is designed to provide your pet with alfalfa timothy hay or other fresh vegetables that it naturally craves & needs. It attaches directly inside any wire cage at any level that is easy for your pet to access & is designed to keep alfalfa & hay off cage floors where it would become soiled. It also eliminates wasted food. Hay Manger also comes with a built-in salt spool hanger so you have a sanitary spot for your critter's Salt Savors.
