Using the criteria tab, you can supply criteria for animals that owner is interested in adopting - it's a cut down version of the find animal screen with just the criteria relevant for a prospective owner.
Ticking the active flag causes this owner's criteria to be included in the list of actively searching owners. You should untick this flag when the owner has adopted an animal. To view matches for currently active owners, run the ``Owner Criteria Search'' report under the Inventories group.
Only one set of criteria can be held per owner.
