Houndsley is sad. Not because it's raining or because there are holes in his sweater, but because he doesn't know when his birthday is. And now Catina is sad, too. But friends are good at cheering each other up, and Houndsley and Catina are the best of friends. So it won't be long before they each discover, in a most surprising way, how a first-rate friend can brighten even the saddest days.
