It's deplorable. Some people don't seem to realise animals have feelings like human beings.
Look at it this way. When we were brought up our parents taught us right and wrong and we learnt values. Nowadays kids are just left to their own devices without reprimand as mothers/fathers are "too busy" or just can't be bothered. So out on the streets they go shooting cats, pigeons you name it for "fun" Then they grow up to be like this person with no regard for life or become fox hunters, pheasant shooters, join illegal **** fighting, hare coursing etc etc. Let your children see this - it will hopefully remain in their minds and ultimately spread the word about these horrible practices.
