When I first took my little kitten in I asked Dr. Joe if he had any suggestions. He said that I should rub "Calley's" cheeks (2 year old and ruler of the house) and then immediately after rub "Zoey's" cheeks. Something about transfering Calley's smell on the baby that whould possibly make Calley warm up to her quicker. I'm happy to report that after the first 2 days I left them alone on a regular basis and with in a week Calley was cleaning and playing with the kitten. Now they constantly mess with eachother.. it's funny!!
