I have no clue why the spayed one is attacking the 9 month old. But I have a pregnant female attacking a neutered male that just happens to be her son from a previous litter. She only does this when my Husband is home. She doesn't attack the other male nor does she attack my 7 month old female. I think it is just one of those mysterious things that just happen. They can't talk so we have no clue as to why they do what they do. All we can do is intervene and try to find acceptable solutions.
