I have one cat who is terrified of black people. Back before my complex got rid of all the grass and replaced it with ugly, nasty gravel, I had two cats that were leash trained. One is nuts and I had to give her a lecture on not talking to crackheads (she was literally meowing out a window to a crackhead who was talking back to her). The other one absolutely hates blacks. I took him out for a walk and two sets of my neighbors came to say 'hi'. He let the Fatties pet him but he climbed me and his his head in my armpit when a black neighbor tried to pet him. The nicest office girl was black and he had fit and cried and hid when I let her in to hear my awful neighbors. She was actually really cool but she was moved to another complex. There's a window that I have a cat bed in and he can see the front door. So many delivery people take pics to prove delivery and make sure to get whoever is in the bed in the picture. Zeke runs if they are black but stays in the bed if they are white. Four of the five of my cats are black, including him, clearly he knows people are different.
