I recently adopted a 4 month old male kitten. I also have a 3 year old female cat. I did the slow introduction thing and at first they didn't seem to mind each other. Now my kitten keeps hunting and jumping on my cats back. It seems like he's playing, but she howls and screams and fights back, but nothing she does seems to "teach him a lesson". Everything I've read says play is silent. I've tried separating them or distracting him with play, but he is fixated on chasing after her. Also, they're both fixed. Are they fighting or playing? Thanks everyone!
