No animals were denied affection or food in this experiment.
- Test 1 (Tucker) Tucker approached the barrier, turned in a circle. Stood at the edge. He would not cross.
- Test 2 (Tucker) Tucker approached the barrier, turned, left the area (He may have been influenced by Gypsy barking in another room)
- Test 3 (Gypsy) Gypsy approached the barrier, walked through it. She knocked down several pens, but I think they were hit by her tail, not her feet.
- Test 4 (Tucker) In this experimental run, Gypsy was on the other side of the barrier. Tucker approached, hesitated, and would not cross.
