Plain milk

Plain Milk

Milk is a valuable resource which unlocks the Kitten series of upgrades that greatly increase cookie output rate in direct correlation to the amount of Milk the player has. Milk is gained by unlocking normal (non-Shadow) Achievements at a rate of 4% milk per Achievement. As of version 2.01, the total number of normal achievements that count towards milk is 378 and the maximum attainable Milk amount is 1,512%.

The Milk is represented by a wave-animated overlay at the bottom of the Big Cookie partition. The overlay gradually gains height as the Milk percentage increases. The milk changes color and name when the Milk percentage reaches a new hundred, although this has no effect on cookie production. New Milk types and Kitten Upgrades have been introduced with new Achievements and the consequential higher possible Milk levels.

Each kitten has a certain factor to milk percentage and provides a total production multiplier. These effects stack multiplicatively. For example, if you have Kitten helpers and Kitten engineers. With 160% Milk, Kitten helpers multiply production by 1+1.6*0.1=1.16, while Kitten engineers multiply production by 1+1.6*0.15=1.24. Combined, these two multipliers will get you a total production multiplier of 1.16*1.24=1.4384.

In addition to the kitten upgrades available in the store, there is one kitten type available through Ascension. This kitten type has a milk factor of 0.1, the same as Kitten helpers.

Possible ModifiersEdit

Besides kittens, there are other factors relative to milk bonus.

milk multipliers
Santa's milk and cookies 1.05
Breath of Milk 1.05
Mokalsium, Mother Spirit 1.1/1.05/1.03
Garden plants (mature, clay) 1+0.0025W
W = # of Whiskerbloom

These are multipliers to the Milk percentage and stack with each other multiplicatively. If you have 160% milk, the effective milk will be 160%*1.05=168% with one of Santa's and aura effect, or 160%*1.05*1.05*1.1=194.04% with all three non-garden effects when Mokalsium been placed in the diamond slot. To reach the maximum effective milk percentage, the Garden should be planted as follows:

W: Whiskerbloom, n: Nursetulip
n n n n n n
n n n n n n
n n n n n n

and the max effective milk percentage can be achieved is:

$ M=1512%*1.05*1.05*1.1*\frac{9241}{8192}\approx 2068.483691% $

The max milk multipliers possible is:

$ (1+0.1M)^2(1+0.125M)(1+0.15M)^2(1+0.175M)^2(1+0.2M)^5\approx 43,385,448 $ However, since Nursetulip will reduce overall cps, the overall multiplier is:

$ (1+0.1M)^2(1+0.125M)(1+0.15M)^2(1+0.175M)^2(1+0.2M)^5*0.5124033903\approx 22,230,851 $

To get the best overall multiplier the best garden arrangement is:

W: Whiskerbloom, n: Nursetulip
W W n W n W
W W n W n W

The effect milk will be

$ M=1512%*1.05*1.05*1.1*\frac{112881}{102400}=2021.361390% $ and the overall multiplier will be

$ (1+0.1M)^2(1+0.125M)(1+0.15M)^2(1+0.175M)^2(1+0.2M)^5 0.9036878906\approx 31,752,571 $

which is 0.144% higher than the arrangement that full of 36 Whiskerblooms .


This image shows the multipliers for each kitten upgrade, based on the milk percentage. In each group of 3 lines, the bottom line is the base multiplier, the middle line is the multiplier with either Santa's milk and cookies or Breath of Milk, and the top line is the multiplier with both. In the endgame, each of the last 4 kitten upgrades triples production.


This image shows the multiplier for the Breath of Milk dragon aura, based on the milk percentage and which kitten upgrades are active. In each group of 4 lines, grouped by color, the bottom line is the base multiplier, the next line is the multiplier with Santa's milk and cookies, the next line is the multiplier with Kitten angels, and the top line is the multiplier with both. The lines for each kitten upgrade assume that all previous kitten upgrades are active as well. Also, since Breath of Milk and Santa's milk and cookies have identical effects, their meanings on the chart can be swapped.

Dunking the CookieEdit

The Cookie-dunker Achievement is gained by accumulating enough Milk and adjusting the browser window in a way that the Big Cookie is overlayed by the Milk graphic on a sizable area. This can be done by zooming in a lot or reducing the height of the page for instance, pressing F12.
