All my animals are spayed/neutered as soon as they are old enough. I now have 4 cats and they have been declawed, all four feet, since they are alone all day and all night. They get into scuffles but, having no claws it never gets serious. I do find tufts of hair sometimes in their room. I've never known of these cats or past cats fighting for territory. I guess I have been lucky, ages range from 14 down to 3 years old. I haven't seen any of them getting mad at each other. They are in a small room, not much room to get away from each other. Good luck.
