Nice card for a girly, it has pink, yellow, and white stripes for the background and to add a little fun the cat wobbles back and forth on a little spring. When you touch the cat in a cupcake it will move back and forth, hence wobble.
I stamped Happy Birthday on the light pink strips and then cut the strips to quarter of an inch and layered the strips with dark pink and yellow and used the card stock of white to be a stripe also.
For the inside I stamped Have a great birthday in pink to finish the card.
