Don't underestimate the value of your kitties

[Arwen Swordthain]

Heres a copy of the calculation I did for a friend a few years ago. Kept the notecard I dropped her.

based on 120 days of feeding and milk
each last 28 days
so
120/28 = 4.3 rounded up so 8.6 per pair
8.6 x 170 = 1462L$
8.6 x 140 = 1204L$

this ignores the fact kittens don't drink milk for the first 7 days taking that into account milk costs are
113/28 = 4.06
8.12 x 140 = 1137L$

total cost to feed and give milk for 120 days = 2599L$ per pair.
that number divide by the number of boxes gives the cost per kitty but does not take into account any time spent

so 2599/16 = 162.44L$
2599/14 = 185.62L$

no milk means
1462/14 = 104.42L$

plus time for spending 30 minutes each day cuddling.

And as stated by Devilness and Ivy that doesn't include any other costs involved in breeding so realistically since you will never sell every box produced the cost per box actually sold will be much higher to cover the cost of boxes unsold.
