the bins are kept at the back of the houses so i dont know whether he doers this all through the week but i have noticed a few times now he has jumped up and pissed in my neighbour's bin. only hers and no-one elses. her bin is always packed so it never fully closes that is how he is able to get into it. one day i saw him push the lid right back over so it was fully open. today i saw him again and when i went to call him away my neighbour came out and chased him aswell. i hadn't reached the door yet so she didn't see me but what can i do? i expect she will be getting pretty pissed off with this but i dont know what i can do except keep in in the house which he hates.
