It's your birthday, its time to celebrate with some Happy Birthday Memes. Time to drag out the 10 year old reused birthday decorations and make yourself a cake. Or just guilt your friends into making the minimal effort to "surprise" you.
But your pet will always want to celebrate with you. Sure they might just be waiting for the right moment to inhale a piece of cake when your back is turned, but they will be just as excited as you, if not more so, for your special day.
