We have an 8 year old Tabby who is usually very playful and loving. On Christmas Eve my wife and newborn son came home from the hospital and at first the cat pretty much ignored the baby. However, there have been several occations since then where the cat hides under my son's cradle while he is sleeping in it, and hisses very aggressivily at my wife as she walks by. Before the birth of my son, my cat and my wife were the best of friends without any problems at all. When I try to step in and remove the cat from the situation, she attacks me as well. I understand that the cat may be feeling jealous, but I thought we took all the necessary precausions to avoid this. Can anyone offer any suggestions on how the 4 of us can get along without any added stress to the cat and especially without any harm to my son?? Any suggestions would be appreciated.
