I think you are being a little harsh..
On second thoughts get him a kitten and make him look after it.
It will give him respect for animals.
Now that's cruel and unusual.
Just kidding cat people!
The presumption with that statement is that he does not already look after the family dog or cat or raise goats or chickens or do any number of things in a responsible mature fashion.
Maybe we should wait until all the facts on this case are covered.
