Ellie has always been our alpha cat. But I have noticed that since her encounter with the dogs she has lost some of her aggressive alpha behaviour. She lets the others eat first, does not fight them off chairs, and engages in more mutual grooming than she used to. Is this normal, should I do anything to restore her self-esteem and confidence, or should I just let them find a new pecking order? I must say it is a relief not to have her jostling the others out of position all the time, but I don't want her to be unhappy.
