If I remember rightly, all the Chinese need to do is have the whole population of the country stand on each other's shoulders and the top most guy chissel pieces off of the moon.
Erm....... The DARk Side of the Moon is in sunlight when the side facing us is in darkness. It is like this for 15 days or so a month.
Cats are just too stupid to use. Anyway Cats only dig holes for one reason only and that is to crap in someone elses' garden.
To put a Cat up there and then make it dig survey holes first they need to plant flower bes or a vegetable garen, belonging to someone othr than the owner of the Cat, at all theplaces that they want surveying. This would negate the reason for sending the Cats in the firstplace as the gardener could survey the MOon himslef.
