With cat tickets, right now, yes, you most certainly should. Not only does it give you chances to better your cats, it can also give you a chance at the rare cat capsule!

Later in the game, it might not matter as much to + level your normal cats (mine are all +40 or higher), but you'll be wanting those rare tickets.
