I agree entirely Steve. My friend across the road has rung the Police (on the non-emergency number of course)and they say it's a hazard on the roads and should not be entering gardens etc. They said the next time it's seen, they'll contact the RSPCA who will sort it out with the lady.
As my friend said, if it were a horse, cow or pig etc people would be reporting it immediately.
It actually isn't 'sweet' - it kicked a little girl in the stomach last week when she tried to stroke it. It's blooming huge.
