Is it possible to make my cat more tolerant?

for some reason yur cat does not like the boys. what are the boys doing to the cat? are the boys teasing or picking on the cat? that would be my guess... watch the boys when they are around your cat. cats are usually mellow when treated kindly. i think that is what the problem is. your home is the cats home, so watch the boys and make them understand that the cat deserves respect.
