We had a jet black cat named Zabo, who ruled the roost where our Doberman Pinschers were concerned. Zabo kept them in order, and all had bloody scratches on their noses till he got them trained. And he loved one of them, Kurt, we even boarded them at the Vet together in the same cage. That shocked the Vet and he made me put them together and just stood back shaking his head. I'll have to admit that Zabo was a savage little beast, hated everyone not in our family, and the Vet began to have a knee jerk reaction to all black cats brought in to him. One friend was upset because when she took her black cat in for a first appointment, he jerked away from it, dropping his stethoscope and asked if it was named Zabo. She never met Zabo and didn't know what he what he was talking about.
Zabo went to the Rainbow Bridge many years ago, but he is still missed and the kids still speak of him.
