Gerritt was already excited and meowing while I was getting the front door open.  Gerritt was very low on water, but did have some food when I arrived in the morning.  After restocking supplies, Gerritt and I played on the couch.  Gerritt alternated between chasing the feather on the string and randomly hurling his body against the couch.  After some more chasing, Gerritt settled down and I pet him on the couch for a long time.
