How long does each "life stage" last for pets?
I'm waiting for an adolescent to become an adult so I can breed him, he's 24 days old and not an adult yet, anyone know how long each stage lasts?
Thanks :]

Eggling -> Hatchling = 3 Days
Hatchling -> Adolescent = 6 Days
Adolescent -> Adult = 18 Days

Total Cycle = 27 Days.

This can be sped up through Magical Pies, Nurtures, Page Views, or just simply having the Eggling start with a headstart.

To add on to what Krin said, it's best to use the pet's image url to see the accurate age of the pet. The pet's age on the pet's profile is indicative of it's age in days since it was created. Some pets don't start at "0" when they were created. This is especially so for pets that were found/ captured from the wild.

Nurturing, page views, and pies also increase the pet's maturity, without changing the pet's age in the profile.

To view the accurate pet's age, copy the pet's image url and at the end of the code, there is a &maturity=___ where the number in the blank is the pet's age in hours.

So pets become hatchlings at 72 hours,
they become adolescents at 216 hours,
and become adults at 648 hours.

Thank you both! :]
