Does my bum look big in this?

Today a hug box arrived containing a furry bed and lots of feather toys (the kind i looove). Plus i get to play with the big box for a few days before my human throws it into the trash. Aren't I lucky?

But, does my bum look big in this picture? I'm on a diet and i think i've lost a little weight but i hear the camera adds 5lbs...
