My husband and I have just secured a house to rent with Romans. We've paid a holding deposit and signed paperwork, even given notice on our current place. In the listing for the house it says 'Cats allowed' and this was confirmed multiple times by the person putting through our paperwork. I received a call today from the estate agents saying that there was a mix up and the landlord has said that we are not allowed our cats and it's either them or the house. Is there anything I can do to fight this? I'm so upset, this was our dream house and I'm also pregnant. Am I overreacting?
