There used to be a lot of rates about 30/20 years ago. That is when the started having a lot of cats. Also they used to come on a regular basis and put rat poison in the drains. But hey have not done this for many years now. Also we have a very big cat population now. It could be that you see a rat and it would be a good idea to report it to the Balladiya, cos I am sure they do not want rats to come back
