CATS being banned at Home

My name is Roshan Dsouza. We have 2 cats at home. Our society secretary has put a issue in our annual general body meeting to ban our cats. We have cats that are indoors they seldom go out, no issues of them entering anyone,s door. Our secretary Mr Luke Lewis is biased and is OK with another member with dog as a pet in their flat, One of my cat 9 months old died of poisoning, we have no concrete evidence as to who did it. My cats poop and pee indoors, but due to one man's jealousy we are facing the burnt. Please help so we can raise a case against this problem. We are animal lovers and treat our cats with utmost care. Please help us.
