I realized i had some new pets, and i clicked on them and i couldn't re-name them, or change their group. The rename button wouldn't show up, and one of my pets had the ''off the ground'' bug.

EDIT: OHNOES now i found misplaced tabs, as if they were on the pet picture when i went to  a person's page.

Can you please say what browser version and OS are you using? And do you have any plugins installed on your browser? Do you have issues with certain pet or with all of your pets?

Previously several users already reported the problems with problematic javascript just like in your case, and it was because of the browser plugins which interrupted our scripts work.
