Birthing a new kitty
Once a kitty is has baked in the oven long enough, you may call this to birth it. Generally this is called for you by the CryptoKitty birthing service.
The first caller to this receives the autoBirthFee that was sent during
the call to breed. All callers after simply burn gas, and there are many
people competing to birth your kitty.

I build these tools in my spare time for fun, but if you would like to buy me a coffee or send a kitty my way, it is always appreciated.
