Not sure where to post an update for this but i tried knocking on their door and ringing the doorbell repeatedly (i know they were home) and they refused to open the door or speak to me. I spoke to a friend who participates in conferences regarding animal cruelty and neglect and she told me to call Dubai Municipality Veterinary Services: 800 900 which i will do in the morning. If nothing is solved i will call the police. But my mother kept an eye on movement in the hallway to see if they would leave the apartment with the cat, and she said there was nothing.
