Clan exclusive pet

I cant find info about food for clan exclusive pet. I try every food but he dont want eat
Where is the timer for item (72h)
If i restart game then timer restart to?
if i hide animal then timer will testart?

 

And he get any %EXP from me?

 

Great, i got the answer. If someone interesting:
This animal no need food.
Timer i feeding meter
When this bar runs out, pet will be gone. There will be no reward or clan reputation from the pet like before, because this content is outdated/removed.
The timer freezes when the pet is unsummoned or character is offline. But it doesn't restart from the beginning.
