Ehhm, my father and I have this habit, calling all cats Puss or Manis (sweety in English)

This is Father's 2nd son He took him in and raised him when I went to the college, I almost thought he was my replacement because for his entire life my father never ever had had pet.

Oh he is a bit rugged now, since he is like the king cat around my neighborhood (love fighting too much) and that becomes a problem now since my grandma picked another male kitten (need not nursing now) and Manis hates him, I get frustrated every time Manis attacks this kitten, what should I do, this kitten is really sweet and cute TT_TT He hates other male cats except this little guy, not mine, but I feed and pet him that he bounces every time he sees me (well, he is Manis' offspring)
