    Patent number: 4483274
    Abstract: The present invention is an animal feeding unit (10) having a body (11) with a hollow interior for containing the feed. Access openings (16) for the animal to retrieve feed from the body interior are provided in a front portion (18) of the unit. The feeding angle of the openings (16) is adjustable through a slot and fastener arrangement (28,29,30) provided for mounting the unit. The slot (20) and fastener (29,30) are located in a rear portion (20) of the body (10). The location of the fastener (29,30) within the slot (28) determines the feeding angle of the access openings (16).
