It seems to me he is creating more stressful social interactions through trying to bring in this cat wherever he goes. I don't think anyone here is against him bringing in Mr. Whiskers, its just most people aren't accustomed to is, so they are uncertain to the laws surrounding it. Its the fact that he isn't willing to help the situation by bringing his documentation (therefore relieving some of the stress), and then suing the business for not complying.
