After the pet has been applied to your character, you will receive an in-game mail containing the egg for your pet. In order to transform your egg into a pet, you will need to visit the Pet Minder NPC in the main city (Sanctum or Pandaemonium) to hatch your egg. Once your egg has been hatched, it will be available in your character’s Pet List. You can access this list via the main Menu button. (The icon looks like an up arrow and is located to the left of your flight meter.) Please be aware there is not a default hotkey to access the Pet List. However, you can create one under the Key Mapping tab in your Options Menu.
For more information regarding the in-game pets, please refer to the following article:
