Small movable window: Pet_Name: Loyalty_Level (Loyalty_Name)
Window size follows the text length
"Pet is hungry" warning under the name when the pet is no longer Happy (yellow = Content, red = Unhappy)
Hunger is re-checked every 15 seconds (configurable), after combat, on pet change and when feeding ends
At max loyalty (Level 6) the window is hidden unless the pet is hungry
Hunters only
Makes no pet queries while you are AFK (keeps the AFK flag from flickering)

Installation

Download the latest AdePet-v1.0.2.zip from the Releases page.
Extract it so the folder AdePet sits directly in <WoW folder>\Interface\AddOns\ (the path must be Interface\AddOns\AdePet\AdePet.toc), remove -main from folder name.
Enable AdePet in the AddOns list on the character select screen.

Commands

Command	Description
`/hungry X`	Set the hunger check interval to X seconds (minimum 1, default 15)
`/hungry`	Show the current interval
`/adepet lock`	Lock the window position
`/adepet unlock`	Unlock the window so it can be dragged
`/adepet reset`	Reset the window position

/adepet debug prints the raw pet happiness and loyalty values (useful for bug reports). /ap works as a short alias for /adepet. Drag the window with the left mouse button; the position and interval are saved per character.

Notes

Hunger detection reads the pet's happiness level (Happy / Content / Unhappy). The 1.12 API does not expose a numeric satiety value, so there is no bar.
Feeding is detected through the "Feed Pet Effect" buff. The check matches the English buff name (this check will not work if using any other language).
Not checking pet state while player have "afk" status. Can cause stange flicker with afk/nonafk status shows in chat, but no longer keeps you online, which can't consider as boting, and I'm to lazy to looking which cause it.
