Claim 0:
1. A device for dispensing at least one food item to animals comprising:
a hollow inner sleeve having:
an inner surface, which delimits a storage volume, configured to receive at least one food item,
an outer surface, which defines a first lateral wall having a first plurality of orifices opening into the storage volume,

a hollow outer sleeve having:
an inner surface,
an outer surface, which defines a second lateral wall having a second plurality of orifices,, wherein the inner sleeve extends along a longitudinal axis within the outer sleeve so as to be coaxial with the outer sleeve,, and wherein the outer sleeve and the inner sleeve have a relative mobility configured to define a variable cover surface of the second plurality of orifices on the first plurality of orifices, wherein the variation of said cover surface generating a variable passage surface between the storage volume and the outside of the device,, wherein the relative mobility comprises a translation along the longitudinal axis,, the device comprising an additional hollow sleeve, extending along the longitudinal axis and having an inner surface and an outer surface, said outer surface defining a third lateral wall having a third plurality of orifices, and wherein the additional sleeve is movable in rotation relative to at least one of the inner sleeve and the outer sleeve so as to vary a cover surface of the third plurality of orifices on the first plurality of orifices and/or the second plurality of orifices,, the device being further such that:
the inner sleeve extends along the longitudinal axis within the additional sleeve so as to be coaxial with the additional sleeve,
the additional sleeve extends along the longitudinal axis within the outer sleeve so as to be coaxial with the outer sleeve such that the order of arrangement of the sleeves from the storage volume to the outside of the device is as follows:, inner sleeve, additional sleeve and outer sleeve,, the device further having an element for locking the translation in at least two different relative positions of the inner sleeve and the outer sleeve.
