I recently noticed that some of the pet headshots on my profile are totally out of alignment, showing a clipped area of the pet's body or even the blank bg area. Is there a way to adjust the area that the frame is around, like you can with the avatar headshot editor? I looked around, but didn't stumble on an option.

yes, on the "your pets" page you can click the little arrow in the top right of each pet's info box. "edit headshot" is the second option on the dropdown list.

Excellent! Thank you so much. :)
