All our bins are raised off the ground now, after Rufus perfected the art of bin raiding. Twice he knocked over the bin and took absolutely everything edible, even stuff which he would refuse if you offered it to him. On both these occasion the entire chicken carcass (cooked) was consumed, even though it had been wrapped up, awaiting transfer to the dustbin the next morning. It didn't seem to do him any harm, although he did pass some blue plastic of unidentified origin. I shouldn't worry, as things would have gone wrong by now. Coming down to the entire non putrescibe contents of the bin spread over the utility room and kitchen floor first thing is a tad annoying. Beware, I went to look for a better bin and there was a woman by them. We got chatting. She told me not to bother with the top touch bin, as her cocker had learnt how to get it it by knocking it over and touching the top!
