Hang on, the original post was about dog owners standing by while their dog deposits a pile of excrement in a public place and fails to clear up. Cats and tortoises tend not to be on leads, they roam freely, therefore pretty unrealistic for the owners to be able to clear up after them.. It is hardly the same thing. You wouldnt be expected to clear up after your dog or tortoise in the UK either. But in the UK you WOULD be required to clear up after your dog so why not do it here too??
