Thank you Elegran. I can confirm that their pee does indeed smell awful and in fact it is the first sign that they have taken up residence again in the garage. Horrid little blighters.
Belfast another appalling attack, we need to ask what is driving this.


we have plenty of owls, buzzards and red kites 

. Not sure how/why they got in jar- there was some water in it, they may have drowned.
