Hay Manger was designed to provide your pet with alfalfa, timothy hay or other fresh vegetables that it naturally craves and needs. Hay Manger attaches directly inside any wire cage at any level that is easy for your pet to access. Hay Manger was designed to keep alfalfa and hay off cage floors where it would become soiled, plus it 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.
