I'm so sorry you're going through this. I know a lot of people who say they're allergic just don't like cats. I know severe cat allergies do exist but are rare. My mom was an asthmatic and she wasn't allergic to cats. She had other things that triggered her attacks and she avoided them. She also made it her problem and not anyone else's. My mom died at 62 from her asthma. He's just one who will not. I agree that if his allergies are real then he never should live in a place that allows animals. They are plenty to choose from and the noise well that's part of apt. living, as long as it's reasonable noise. Not loud music or parties. Honey please don't stress. Like some have said, this is not your fault. You did nothing wrong. Play nice and also be polite.
