So it is intended to be battle.net wide for the pets that can be shared. This should include almost all (if not all) of the current vanity pets. Several of the mounts are not going to be account wide depending on how they were originally intended to be acquired.
Quote:Account-Wide Pets
Pets are now account-wide. This means that any pet you have on one character will be shared with all of the others on your Battle.net account. Earn level 6 with Grunty on character A? Log in character B and that level 6 Grunty will be there waiting for you.If you have multiple versions of the same pet on multiple characters on your account, they will be merged into one. We will place any extras in your bags or mail them to you if you are out of space.
