Animal Removal

I need help!

Gulden park strand complex, just forward me an email to remove my cat from my flat. The complex doesn't allow pets and ive been having this cat for 4 years . There has been pets for years, many residents are okay with it. Unfortunately here is a man who bred Rabbits and sells them for personal income, has now requested to remove all cats due to the assumptions of cats eats this baby Rabbits. I am busy applying for approval but I'm so unsure about where I stand. Is there any one that can assist me please.
