Once you're the proud owner of a MoonCat, what can you do with them? Well, obviously you can CUDL them and admire them in your wallet viewer, but there's a wide Ethereum world out there, and several applications offer perks and bonuses to MoonCats and their owners:
MoonCat AcclimatorponderwareA good place to stop by first, after adopting a MoonCat. MoonCats that have spent their whole lives on the moon need a little help adjusting to their new environment.
