We are currently having building work at the moment so we don't live at our new house, I was looking out the window from the new extension and saw a massive rat in next doors garden, she has a lot of dogs (she breeds them) so my heart was in my mouth thinking her dogs were going to get injured, as they are only small dogs, but luckily the rat vanished when they came outside. I mentioned this to the builder and he said he has seen loads of them next door and he went to speak to her. Turns out, she knows she has them and has had them for a while, she calls them her pets and doesn't want to get a pest controller in as she doesn't want to harm any animals 
I don't want to move into my new house with lots of rats living next door as I have children and also a dog myself. I spoke to my local council who said it's not their problem and I need to speak to citizens advice as it's a legal problem and I will need to take her to court for an enforcement order. Surely this isn't right, isn't it an environmental problem, any advice on what to do?
