Claim 9:
10. A device for determining whether to one of open a door, signal, and issue feed for an animal, comprising:
an image recording device adapted to capture images of an approach procedure of the animal located in proximity to the device, the approach procedure comprising a trajectory of the animal;
a database adapted to store reference images of a reference trajectory of characteristic procedures of approach of the animal;
a pressure sensor in proximity to the door configured to capture a weight; and
a control device coupled to the database and the image recording device, the control device determining a degree of matching between:
the trajectory and the reference trajectory; and
first features of the images and second features of the reference images;

wherein, depending on the degree of matching, the control device activates one of:
a drive for opening a door;
a signalling unit for issuing one of an alert tone and a luring sound; and
an issuing unit for issuing feed;

wherein the control device is further configured to determine if the animal is holding a captured animal in jaws of the animal by at least one of:
comparing the images and the reference images; and
comparing the weight captured by the pressure sensor with a reference weight of the animal; and

wherein the drive for opening the door is actuated only if the animal is identified as not holding the captured animal in the jaws.
