The only possible answer to the question in the title is that the girl lacks sufficient morality to treat animals decently. That must be a parental failure. This girl who is 12 years old was caught on CCTV cameras dumping someone else’s cat into a rubbish bin and then dumping a bag of rubbish on top of the cat to make sure that he stayed in the bin. As it happened he escaped and we hope that he is well. The girl and her mother turned themselves into the local police station after the video went viral on the Internet which forced their hand. The idea no doubt was to prevent her being arrested and charged.
