An animal feeder 10 comprises a container 11 into which liquid feed for a young animal can be placed. A mounting arrangement 12 coupled to the container is of a construction which, in use, enables the container 11 to be attached to an element of a structure such as a rail of a fence. At the lowermost part of the container 11 is a teat mounting 13 which has at least first and second teat mountings 19 and 20. The first teat mounting 19 has a different orientation relative to the container 11 to that of the second teat mounting 20. As a result an end user of the feeder can select one of the teat mountings 19 and 20 for the mounting of a teat P depending on whether the end user wants the teat P to project away from or through the fence on which the container is mounted. A bung or blanking plug 24 is used to seal the other teat mounting.
