Please lah, don't be such an ass****. 
If you really need help with the cats, pls contact the cat welfare
society for cat repellent. They do help out with these things.
Otherwise, leave some dry cat food outside for the cats so they
won't go into your home to steal the bread or whatever (as if cats
will really eat bread?? ) . You have a house, so you can afford the
little bit of cat food.
