I have 2 cats (ages 14 and 12). The 14 year old Cody just had surgery today and he's a long haired cat so I had him shaved all over. When I brought him home today, the 12 year old Skylar hissed and growled and attacked him twice. I'm having to keep Cody shut up in my son's room or Skylar shut up in my room. Is this normal? Why would Skylar suddenly start growling at and attacking Cody?
