We live in a London semi. A few months ago our cat starting bringing in dead or half dead rats over a period of a week or so. This past week it is started happening again. I'm fairly sure they are breeding in our neighbour's compost bins as we've had our cat 2 years and this only started happening since they installed the compost bins last autumn. I'm going to talk to them about it but I'm a bit concerned that their solution will be to try and poison the rats and I'm worried my cat could get poisoned as she is a real hunter. Has anyone got any advice before I approach the neighbours?
