Just checked on my neighbour's cat... some waste of skin thought it would be fun to wrap an elastic band around her paw and think that she will be okay as her paw is swollen but warm and the next few hours will tell alot.
My neighbour is a retired doctor so she knows what to look for and loves this cat more than anything... it showed up one day and adopted her and is the sweetest thing.
People who do this kind of thing need to be beaten... repeatedly.
