My Battle Pet Notifier is a tool I wrote to assist with finding battle pet and assisting with capturing rares. When starting a battle, a side window appears showing you what the pets are that you are battling, in addition to what you currently have of that type. For rare hunters, a button is available to quit the battle without confirmation. If a rare of a type you do not have is in the battle, this button is greyed out to prevent accidental quitting.

I also have a search functionality to assist with your adventures in captures. Either use the minimap icon (which also plugs into fubar and titan panel) or use the command line. In the tree window, if you click on a pet type from a zone and you have the addon TomTom, all the points where you have encountered this type will appear as dots on your map.

A tally window is available to show some various stats - how many unique rare types, rares you have with non rares, etc. Some of these are clickable to give more details in the chat window.

Slash commands:

/pets [reset] - alternate method to open the search panel (the reset option rebuilds the search window in case it gets tainted)
/tally - open the tally window
/petdb clear - clears the database of points for the pet battles.
/plot - If TomTom addon is installed, this command will plot a waypoint to all the battle pet tamers that have daily quests that have a bag as a quest reward.
