PetCaught 

Note: Blizzard is implementing this functionality into the default UI with Patch 5.1, so this addon will be made obsolete at that point.

What's this?

PetCaught is a very simple addon that appends a "Caught" or "Not Caught" note to the tooltips of any wild battle pets you may encounter. The goal is to help you catch 'em all more easily, removing the need to check the pet journal to determine if you've already captured a certain pet.

The addon will add the note to both world tooltips as well as minimap tracking tooltips. In addition, it will note the quality of your captured pet (for example, Poor, or Uncommon) so that you can decide if you want to try to capture a higher quality of a pet you already have.

PetCaught has no UI or configuration, just drop it into your addons folder and you're good to go. If you've got suggestions or screenshots, let me know in the comments below.
