Cats and Pit bull fighting
One of the issues that was mentioned about cat issues in Baltimore, where I am right now, is that in pit bull fighting - which is unfortunately becoming more prevalent - it seems that some people toss cats (or other animals) to the pit bulls for practice. One of the ladies I was speaking with at Alley cat Allies was saying that people have been known to pick up their pit bulls and toss them into colonies of cats to let them practice on the cats. She had asked if we had experience with dogs killing cats in Singapore - I emailed back to say that while there are cases of dogs killing cats, those are usually dogs that are themselves homeless and usually abandoned/left behind. There have even been cases of people letting their dogs off leashes to chase cats - but so far I have not heard of cats being used for practise for dog fighting.
It's terrible what people will sink to do - and not just to the cats, but to the pit bulls and other animals that are thrown TO the pit bulls.
