In addition to the numbers (say 5, 15) can you also put the common letters (e.g. S/S) in your pet breed info? I don't know about others but I find it a heck of a lot easier to see "S/S" then to recall 5, 15.
Yes, I do know you can click the "?" but when you are on an iPhone looking at a pet up in the mobile AH trying to figure out what breed it is (by matching the stats against the listing), this can be a tad cumbersome (not to mention sliding the level slider back to 1.)
