You pretty much just go to your inventory and use it, just like any other item. The page that comes up will show the ID numbers of any dead pets you have - you can go to the graveyard on Reiflem to see what type of pet each one is.

No, you can only use it in the pets in your graveyard.
If they were to allow us to do otherwise, it would essentially be stealing and would pretty much devalue all pets.
