A few weeks ago, I posted about a dismembered pigeon in my alley. For the last couple of weeks, when I go out the front, there is a lovely cat outside my alley gate. She is wearing a collar and doesn't look starved although the colar is tatty. I guess it must have been her that ate the pigeon. Anyway, when I go out, the cat runs away (I live on a busy high street). It runs through my front garden, through the vets front garden and down an alley next to an empty property. There is a room at the back of the alley with a door but as its derelict, there are ways to get out the back. I went to close the door after the cat to stop it coming through again but it ran out the door and further up the road. I don't know what to do as I can see an RTA waiting to happen - If I corner it, it could run into the road. No doubt it belongs to someone that lets their cat roam so I just don't know what to do.
