I like using all of the available ID numbers. Is it possible to get the ID numbers for caged battle pets? I am trying to figure out how different breeds, levels, etc are identified. I sell a bunch on the AH and TSM is useless when it comes to differentiating.

Rematch might show you this, but as far as Blizzard tooltips go, we haven't had any success getting ATT tooltips to appear on them. If you find an addon that does, please let me know.
