Custom quests that use pet eggs

[Naruhodo]

I still want to catch 'em all and get rid of all the taming items stuffed up my Kafra-land.. and then get rid of the eggs too. New strong pets are good, but I still need to do stuff with all this old pet crap

I agree that a Pet Adoption repeatable quest would be perfect and fun. Perhaps the quest NPC could ask for a different pet each day and have rewards similar to the Blank Card rewards or whatever the GMs deem is most balanced and fun.
