What happens if you don't feed your pet? Also, is there anything like an autofeeder system to feed my pet? I feel like Angelbird is always hungry and I'm constantly feeding her and it's annoying.

Nothing really happens, but you won't be able to battle with that pet. You can put your pets in the resort or the Rathskeller Inn to keep them fed and played with, but you won't be able to use them for Major Drills quests that require feeding/playing with a pet if you do those

Thanks, . I'm still learning! But I appreciate the info a lot!
