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 2.011, the total number of normal achievements that count towards milk is 395 and the maximum attainable Milk amount is 1,580%.

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.


As the player gained more and more (non-shadow) achievements, Milk will change its appearance and flavor.

After you purchased the "Fanciful dairy selection" heavenly upgrade, you may freely choose the flavor of Milk. Furthmore, there are 9 more types of Milk - Zebra Milk, Cosmic Milk, Flaming Milk, Sanguine Milk, Midas Milk, Midnight Milk, Green Inferno Milk, Frostfire Milk and Soy Milk. These new types of Milk are unique in introducing not only new colors, but new patterns to the Milk.

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. You can check the overall Kitten multiplier in top of Achievements section in Stats.

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.

The effect of Garden plants on Milk percentage is much more complex. The power of Whiskerbloom can be increased by Nursetulip, but Nursetulip itself will reduce overall CpS. See following examples for detailed discussion. All examples assume that:

  • The achievement is 1580% (maximum as v2.012)
  • Including all other 3 non-garden modifiers.
  • All plants are mature
  • The soil is clay.

Example 1Edit

A full 6x6 plot of 36 Whiskerblooms has a modifier of fW = 1+0.0025*36 = 1.09, and combining all other three non-garden multipliers will give the effective milk percentage:

$ M=1580%*1.05*1.05*1.1*f_W\approx2088.59805% $

The resulting Kitten multiplier will then be:

$ K=(1+0.1M)^2(1+0.125M)^2(1+0.15M)^2(1+0.175M)^2(1+0.2M)^5\approx 171,517,188 $

Example 2Edit

To reach the highest possible 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

The overall Whiskerbloom modifier will be:

$ f_W=1+\frac{1}{400}\left[2\left(\frac{5}{4}\right)^2+4\left(\frac{5}{4}\right)^3+4\left(\frac{5}{4}\right)^4+8\left(\frac{5}{4}\right)^6\right]=\frac{9241}{8192} $

The max effective milk percentage which can be achieved is:

$ M=1580%*1.05*1.05*1.1*f_W\approx 2161.510735% $

The expected resulting Kitten multiplier for this would be:

$ K=(1+0.1M)^2(1+0.125M)^2(1+0.15M)^2(1+0.175M)^2(1+0.2M)^5\approx 240,967,763 $

However, Nursetulip reduces overall CpS by a factor of:

$ f_N=\left(1-\frac{1}{40}\frac{5}{4}\right)^6\left[1-\frac{1}{40}\left(\frac{5}{4}\right)^2\right]^{12}=\left(\frac{31}{32}\right)^6\left(\frac{123}{128}\right)^{12}\approx 0.5124033903 $

Which means the overall production multiplier is only fNK = ~123,472,699. Thus, despite having the largest possible Kitten multiplier, this setup is far less efficient due to the Nursetulip factor.

Example 3Edit

To offset the Nursetulip debuff, the best garden arrangement is:

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

The total Whiskerbloom modifier for this setup is:

$ f_W=1+\frac{1}{400}\left[11+12\frac{5}{4}+8\left(\frac{5}{4}\right)^2+\left(\frac{5}{4}\right)^4\right]=\frac{112881}{102400} $

The effective milk percentage for this setup is:

$ M=1580%*1.05*1.05*1.1*f_W\approx 2112.269177% $

Which gives the Kitten multiplier:

$ K=(1+0.1M)^2(1+0.125M)^2(1+0.15M)^2(1+0.175M)^2(1+0.2M)^5\approx 191,496,053 $

The Nursetulip factor will be:

$ f_N=\left(1-\frac{1}{40}\right)^4=\left(\frac{39}{40}\right)^4 $

With a resulting overall production multiplier of fNK = ~173,052,664, which is ~1.4 times as much as the previous example, and 1.072% higher than the simple arrangement of 36 Whiskerblooms.



The top 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.


The bottom 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.
