Animal feeding teats are often removed from a feeding receptacle for cleaning or for re-use on a larger receptacle. A nipple end of the teats is typically designed for use in a specific orientation to aid the suckling of a young animal, and therefore the teats need to be fitted to the feeding receptacle correctly. The animal feeding teat according to the present invention has a rectangular connection feature in a base end of the teat that is designed to mate with a similarly shaped feature on a feeding receptacle. It is considered important that the connection feature has only one or two lines of symmetry, so that the teat can only be fitted in one or two orientations relative to the receptacle. The teat is retained on the receptacle by a separate retention system.
