Using the criteria tab, you can supply criteria for animals that owner is interested in adopting - it's a cut down version of the advanced 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 also need to set a date to make the criteria active, and optionally one to make it inactive if you would like to give up looking after a period of time. To view matches for currently active owners, run the ``Owner Criteria Search'' report under the Reports->Inventories.
Only one set of criteria can be held per owner.
