The authorities here take the view that they are native/natural and are ignoring that they are of such numbers they are a real problem. In cities there is so much rubbish and litter that is easy pickings for them and they make a big mess when they knock bins over. I can cope with the mess, it's the poo on the garden, particularly with a 2 and a half year old that loves to be outside, thats the problem. Although watching the beast climb on my wood a few times ..hmmm, when he did that on a pile I'd yet to stack it made me cringe somewhat.
