I decided to start the labor day weekend out early and take the day off of work. Zoey got to run loose in the house most of the day. Alot of the hissing has subsided, and she seems to be adjusting well. She now chases Ozzy around and jumps at Lucy in an attempt to play. They both have been very good about this new little intruder in the house. After lots of running around today, she finally took a rest. And I was glad, as I am not used to all that running and jumping about either!!
