An animal feeding dish having a relatively shallow-food holding bowl that is upraised from the floor by a platform or pedestal so as to minimize whisker contact of an animal eating from the dish. The platform or pedestal can include spaced apart outwardly extending supports that shield interiorly disposed legs carried thereby from food dropped during eating while also preventing tipping of the dish. Such a bowl can be a spherical section having an advantageously large radius of curvature, including relative to bowl width or diameter, which produces a desirably shallow depth bowl that prevents whisker contact. The bottom most portion of the bowl is spaced suitably high relative to overall dish height to more optimally position the mouth of the animal during feeding to further minimize whisker contact.
