He was mad at me all day yesterday! Every time I talked to him he would turn his head the other way. When I left the room he didn't call for me like he usually does. When I needed him to step up to put him to bed for the night, he gave me this look, growled and then stepped up. He did what I asked, but he made sure I knew he wasn't happy about it, lol! He seems ok this morning...we are playing peek-a-boo, which he initiated...so I guess he is done giving me the silent treatment ...for now anyway!
