It's not easy to put the harness on Mocha. I had to struggle for more than 5 min to put it on. After putting the harness on, Mocha tried to fly away many times and crashed onto the floor. After awhile, Mocha settled down a bit and I cautiously took him outdoor. I just walked a few steps outside my house. I was afraid Mocha would take off anytime without warning. To my surprise, Mocha stood still on my finger and enjoyed the walk and the new surroundings. We had a wonderful short walk.
