I want the two cats to stay in at night. The young male has too much energy. He ran out when I was letting my little dog back in. The only way I could get him to come is pretending I had a treat and I felt I had to follow through for him to believe me in the future. I gave him greenie treats but it was short lived. He harrassed his mother and I had to intervene. The male was not happy and is looking for trouble. I don't know how I am going to keep them in during the warm weather.
