University of Illinois researchers studying a contraceptive vaccine called GonaCon developed a unique study environment intended to mimic free-roaming cat populations. Cats were housed in a large, two-level open enclosure with many enrichment opportunities, including a climbing tree, furniture, toys, scented objects, hidey-holes and an outdoor enclosure.

Volunteers also played with and trained the cats. Instead of using lab cats, cats were brought in from a local shelter. Although GonaCon ultimately was not shown to be effective for preventing pregnancy, lead investigator Amy Fischer believes she will use the hybrid research/shelter facility in the future to test new contraceptive technologies.
