🚨🚨🚨🚨 Due to network congestion, we are increasing the birthing fee from 0.001 ETH to 0.002 ETH. This will ensure your kittens are born on time! The extra is needed to incentivize miners to add birthing txs to the chain. Long-term solution will be explored very soon! 🚨🚨🚨🚨

Graphs

Ralf Putmans (DerpyBastard) has graphed these birthing fee values against the ETH/USD price to chart the breeding price in USD over time (from November 28th, 2017 up through April 14th, 2018):

Birthing Fee

The average breeding price in USD over this entire time period is $6.06. Since the distribution of cats is skewed, the average amount spent to actually breed each kitty would be slightly different. You could overlay the births/day to calculate that number.
