I feel like making the list of birthday cupcake pets in the pound visible to ranks ck and higher would be beneficial in multiple ways - one being reducing the risk of identity exposure; for instance, on multiple occasions I have clicked on one of the pets on the list and clicked on the "adopt" link and got the "Sorry, this neopet already has an owner and is very happy!" message. All it takes is searching for that neopet to find the username of who adopted it.
Also it would increase the amount of CC pets that are actually still in the pound on their birthday which would be great, too!
Just an idea
