In Kittens Game, the hover text (using "Theme by Kida") for festivals looks like the following:
Hold a cultural festival to make your kittens happy. (+30% to happiness and double growth rate for a year)
The wiki page doesn't explain what "double growth rate for a year" means, and it's not clear what exactly can "grow" (it's certainly not kittens).
Question: During a festival, what does "double growth rate for a year" imply?
Best Answer
It refers to the time span between when you build a house and the time the kittens spawn in it.
Especially during endgame scenarios where you build a lot of houses quickly, it's nice to have them fill up faster. Some metaphysics upgrades also affect this behavior.
