1. A rotatable animal feeder, comprising:

1. first means for supporting said animal, said first means being provided with an access opening for said animal;

2. second means for covering said first means to confine said animal;

3. third means rotatably mounting said second means on said first means;

4. fourth means carried by said second means for restricting said animal from a portion of said first means, whereby said animal must push said fourth means away from said portion of said first means to obtain food placed on said portion of said first means; and

5. fifth means placing said access opening in communication with an animal cage, said first means comprising:

A. a platform having a bottom wall and an upstanding side wall, said access opening being provided in said bottom wall; and

B. a spillage guard upstanding from said bottom wall and spaced inwardly from said side wall for forming a channel between said side wall and said spillage guard.

2. A rotatable animal feeder, comprising:

1. first means for supporting said animal;

2. second means for covering said first means to confine said animal;

3. third means rotatably mounting said second means; and

4. fourth means carried by said second means for restricting said animal from a portion of said first means, whereby said animal must push said fourth means away from said portion of said first means to obtain food placed on said portion of said first means, said third means comprising:

A. a dome having an encompassing side wall, said fourth means depending from said dome; and

B. a cylindrical boss depending from said dome, said boss being rotatably mounted on said first means.

3. An animal feeder comprising:

a cage for housing said animal, said cage having an opening provided therein;

a tubular member having one end mounted in said opening in said cage and having a second end;

a platform connected to said second end of said tubular member, said platform having an opening provided therein in communication with said tubular member, whereby said animal has free access to said cage and to said platform;

a pivot pin upstanding from said platform;

an upper housing rotatably connected to said pivot pin, said upper housing including an encompassing side wall having a lower edge extending to a position closely adjacent said platform for caging said animal in said upper housing; and

at least one feeding compartment provided in said upper housing, said feeding compartment having an encompassing side wall, an open top and a bottom wall, said bottom wall of said compartment being provided with an opening through which food may be dropped onto said platform below the bottom wall of said compartment, said encompassing side wall on said compartment preventing said animal from having access to said food without pushing said compartment to rotate said upper housing until said compartment moves past said food.

4. A rotatable feeder for animals, comprising:

a platform having a bottom wall, an upstanding side wall and an open top, said bottom wall of said platform having an opening provided therein;

a cylindrical member having an encompassing side wall defining an open end and a closed end, said open end of said cylindrical member being mounted in said opening in said bottom wall of said platform, said encompassing side wall of said cylindrical member being provided with an opening so that an animal may gain access to said platform through said cylindrical member;

a post affixed to said closed end of said cylindrical member; and

a dome rotatably mounted on said post, said dome including a side wall having a lower edge disposed adjacent the encompassing side wall on said platform for confining an animal to said platform, said dome also including a pair of feeding compartments each having an open top, an encompassing side wall and a bottom wall, said bottom wall of each feeding compartment extending to a position sufficiently close to said platform that said animal cannot pass between said bottom wall of said compartment and said platform, said bottom wall of said compartment being provided with a small opening through which food may be dropped onto said platform in such a position that said animal must push against said compartment and rotate said dome on said post in order to gain access to said food on said platform.

5. A rotatable feeder as stated in claim 4 including an annular spillage guard on said platform adjacent said platform side wall for forming an annular channel in which said lower edge of said dome side wall is disposed.
