All About Cattributes

UPDATE: My discussion about terminology with Alanfalcon has spurred the adoption of several new terms among the CryptoKitties staff, which you might see them use in the near future. Instead of dominant (D0) and recessive genes (R1/R2/R3), they might refer to active (A0) and hidden genes (H1/H2/H3) for normal cats and H0/H1/H2/H3 for fancy cats. In addition, they prefer classifying genes found in Generation 0 cats as Level 1 while Wingtips is a Level 3 gene (instead of using the “Tier” keyword).

Every cat has a cattribute/trait in 8 different categories which each has an impact on the visual appearance of the cat (except for Fancy cats). There are also 4 additional categories which are normally hidden.

If you do not understand basic CryptoKitty genetics, including how dominant and recessive genes work, then I recommend you start with some older CryptoKitties411 articles:

The 8 primary cattribute categories are:

  • Fur / Body
  • Pattern
  • Eye Color
  • Eye Shape / Type
  • Base Color
  • Highlight / Pattern Color
  • Accent / Secondary Color
  • Mouth

One detail that is often missed is that the background of the cat image is determined by the Eye Color of the cat.

There are also 4 additional hidden categories. Basic Wild genes do not seem to do anything but Tier 1 Wild mutations (e.g. Elk, Trioculus) are additional cattributes which are displayed and impact the visual appearance of the cat. At this time, it is not known what Mystery, Secret, and Unknown genes do, though there is plenty of rampant speculation of what they might do.

Fancy cats of a given type all have the same physical appearance though the background color does change depending on Eye Color. Fancy cats are assigned a numbered Fancy badge instead of having cattributes displayed. However, they still have relevant dominant and recessive traits which can be passed down to their offspring. And while none of their family or mewtation jewels are displayed, these still exist and can be passed down as well.

Not all cattributes are the same. Some are much rarer or more valuable than others. To help you better understand the nature of cattributes, here are some broad categories that are sometimes used. Most of these terms are used colloquially (instead of there being an official definition) so there may be slight differences in meaning or usage.

Normal / Base Traits

“Normal” often means the standard traits that do not fit in any of the other categories (not mutations, retired / discontinued, or founder traits).

Sometimes, “Base” trait is used to refer to all non-mutation traits (which may include retired / discontinued and founder traits). So Jaguar might be considered a “Base” trait but not a “Normal” trait.

Founder Traits

The first 100 cats are the Founder cats and they are each assigned a special Founder badge. Every Founder cat has the following genetic makeup for their dominant and recessive genes:

Fur: Himalayan, Munchkin, Ragamuffin, or Sphynx
Pattern: All Founders are 100% 🐎 Purebred Jaguar
Eye Color: Chestnut, Mintgreen, Sizzurp, Strawberry, or Topaz
Eye Shape: Crazy, Simple, or Thicccbrowz
Base Color: All Founders are 100% 🐎 Purebred Orangesoda
Highlight Color: Chocolate, Coffee, Lemonade, Royalpurple, or Swampgreen
Accent Color: Granitegrey or Kittencream
Mouth: Beard, Happygokitty, Pouty, or Soserious

Jaguar is a special case because among Generation 0 cats it can only be found among the original 100 founders. That means that any higher generation cat with a Jaguar gene is a descendant of at least one of the Founder cats.

Beard, Chestnut, and Simple are also notable cases because the only Generation 0 cats with dominant Beard, Chestnut, or Simple are some of the Founder cats. These genes may appear in non-Founder Generation 0 cats but only as recessive genes.

The traits listed above are collectively called Founder traits because they were present in those original cats. However, these genes can be found in other Generation 0 cats as well (except no Beard, Chestnut, or Simple as dominant and no Jaguar at all).

Since jewels were introduced much later, Founder traits are also notable because they do not have associated jewels (no diamond, gild, amethyst, or lapis). This can be an important consideration for players who want 8 jewel or 9 jewel cats.

There are also some additional jewel-less traits that are often considered Founder traits even though none of the 100 Founder cats technically had any of these genes:

Pattern: Luckystripe, Totesbasic F, and Totesbasic G
Base Color: Aquamarine, Greymatter, Salmon, and Shadowgrey

These cattributes can be found in some of the earliest cats (e.g. Bug Cat exclusive, 500-number cats) and other low number cats (e.g. Knight Kitty exclusives).

Retired / Discontinued Traits

Over time, some traits are phased out and no longer appear in new Generation 0 cats. These are referred to as “Retired” or “Discontinued” traits. Note that this is not an official designation. There is nothing to prevent Axiom Zen from including these genes again in upcoming Generation 0 cats but that has not happened so far.

An older list of Discontinued traits can be found here:

Discontinued Traits

I do plan to write an article in the near future to update the list of Retired / Discontinued Traits.

“Recessive” Traits

Recessive traits (which is different than recessive genes) is sometimes used to refer to traits that show up in recessive positions (R1, R2, or R3) in Generation 0 cats but are not expressed (D0) in any of those cats. The only way for these genes to become dominant is to breed the cats until gene swapping causes them to move into the D0 position.

The following traits can be found as recessive genes but not dominant in Generation 0 cats:

Fur: Chartreux and Savannah
Pattern: Calicool, Camo, Ganado, and Spock
Eye Color: Doridnudibranch and Forgetmenot
Eye Shape: Baddate, Otaku, Serpent, and Stunned
Base Color: Dragonfruit, Harbourfog, Hintomint, and Nachocheez
Highlight Color: Apricot, Barkbrown, Lilac, Poisonberry, Scarlet, Springcrocus, and Violet
Accent Color: Belleblue, Emeraldgreen, Missmuffet, and Peach
Mouth: Belch, Gerbil, Wasntme, and Whixtensions

Since it requires gene swapping to get these traits into a dominant position, it is rarer to see these cattributes expressed among low generation cats.

Furthermore, some recessive traits are rarer than others. For example, Chartreux can only be found in the R3 position of Generation 0 cats while Camo can be found in R2 or R3, and Otaku can be found in R1, R2, or R3.

As a result, for Generation 1 cats, a Chartreux is rarer than a Camo, which is rarer than an Otaku, which is rarer than a normal trait like Totesbasic or Granitegrey.

I will be going into more depth on these recessive traits in an upcoming article.

Mutation Traits

When two cats breed, certain pairs of traits can mutate into a new trait. For a primer on mutations, please take a look here:

Mutations

Mutation traits simply do not appear in Generation 0 cats as dominant or recessive genes. So if you see something like this:

https://www.cryptokitties.co/kitty/21391

You know there is something wrong because Tigerpunk is a mutation and Otaku is a recessive trait so neither should be dominant in a Gen 0 cat. If you actually look at this cat’s genetic code, you will see that its Pattern is really Totesbasic F and its Eye Type is Thicccbrowz. So this is a front-end bug with the website.

It takes time for mutations to propagate so low generation cats with mutations can be extremely valuable and 🐎 Purebreds are not even possible until several generations have passed.

Note that there is some variance with terminology. Most people seem to refer to Cloudwhite as a Tier 1 mutation and Wingtips as a Tier 2 mutation. However, there are some people who refer to all base traits (non-mutations) as Tier 1, which would make Cloudwhite Tier 2 and Wingtips Tier 3. Furthermore, Alanfalcon has been advocating the use of “ascension” instead of “mutation.”

How are fancies “released” and “discovered”?

When a certain combination of traits appear together in a cat, it becomes a fancy cat. For example, if you breed a cat that has onyx, henna, wolfgrey, and slyboots, you will get Negato the Ninja Fancy.

But underneath their ornate exterior, Fancy Cats are a lot like other cats. Their genes work the same way, and they can come from ordinary parents. Really, the only thing that separates a fancy cat from a regular one is its artwork.

What this means is that Fancy Cats are not determined in the smart contract on the blockchain. They are determined solely by their display on the CryptoKitties website.

Developers can therefore “release” fancy cats in this manner. They go into the code for their website display. Normally, cats are just displayed as the sum of their cattributes:

If cat has googly eyes, display googly eyes.
If cat has sphynx body, display sphynx body.

But if developers want to release a fancy, they just a) find a trait combination that doesn’t currently exist in any cat, and b) adjust the code to override the standard picture with a fancy picture if that combination appears.

If cat has googly eyes, display googly eyes.
If cat has sphynx body, display sphynx body.
BUT if a cat has googly AND sphynx, display MISCHIEVOUS FANCY CAT.

What This Means

Recently, the developers announced that they would release a Golden Fancy Cat in honor of their being nominated for the Golden Kitty Award. Basically, they did not plan and code a Golden Fancy from the game’s inception. They just decided to do it because something special happened.

Because the “recipe” for a fancy cat usually incorporates related cattributes, we can assume that the developers will require “gold” as part of the recipe. What else might it require? Orangesoda? Daffodil? Lemonade? Let’s check the Marketplace to see if that combination exists. When you search the Marketplace for that combo, make sure to select “All Kitties” instead of just the ones for sale. 

golden kitty

Yes, it looks like those exist already, so that can’t be the formula for the Golden Kitty. Maybe we could throw in the ganado pattern? Does that exist? No! It doesn’t yet!

So if you’re feeling especially lucky, you can follow your hunch and try to create a cat with gold, orangesoda, daffodil, lemonade, and ganado. Chances are that it won’t turn into a fancy, but you never know! You might get the first one!

What This ALSO Means

Don’t try to create the next Halloween Fancy Cat right now. Even if you have a hunch, chances are 1) the required traits are even released yet, or 2) the developers haven’t assigned it a formula yet. So if you create that combo right now, it’ll just be another combination that “already exists” and won’t be in consideration for the fancy. That’s my opinion, anyway.

CAVEAT

I actually don’t KNOW how fancies are released. Some players are convinced that all the fancies have already been decided and programmed. They may be right. But I personally don’t think so, especially because of the developers deciding to release a Golden Kitty (and naming it in honor of Earn.com, the winner of the Product Hunt contest). That feels spur-of-the-moment to me.

I also think that this method of releasing fancies allows the developers to time the fancies with events, such as holidays or new region launches.

Happy Fancy Hunting!

Which Traits are Rare?

There are two kinds of rarity in CryptoKitties, immediate rarity and long-term rarity.

To find out what traits are rare RIGHT NOW, the best tools to use are CryptoKittyDex or the KittyExtension. They tell you the current rarity of traits. You can also check the news section of my sidebar to see what traits have just been released. The newest traits are  the rarest ones in the immediate time frame.

If you want to know what traits will hold their rarity for a longer period of time, check out the Trait Chart. The traits near the bottom are mutations. The darker the blue, the more mutations it requires to breed into that trait. Those traits are usually more rare in the long-term, especially in low-generation cats.

(And if you want to know what traits will be rare in a REALLY long time, look at the boring basic traits that everyone is trying to breed out of their cats. If everyone is trying to mutate out of those traits, it’s possible that those original basic traits will slowly become rare over time. [Excepting totesbasic, which currently has three genes that map to it.])

Maximize Your Mutations!

To understand mutations, please read this post first.

We know how genes mutate, and we know that stacked mutations–especially in low-generation cats–are generally more valuable. So I’ve created a tool to help maximize mutation potential.

Ahem.

Is your cat’s life dull and drab? Is she tired of giving birth to boring kittens?
Does she want to spice up her life with MUTATED OFFSPRING?!
Then I have the dating service for you!
Use this sheet to find the ideal partner for your CryptoKitty to maximize the odds of mutations.

A DOUBLE Fancy?!

Related post: How to Make Fancy Cats.

UPDATE: Bad news, guys, there’s no double fancy. *weep* Check out this cat: https://cryptokittydex.com/kitties/395204. It has all the traits required for Mistletoe (crazy, oldlace, gerbil) and Dracula (laperm, spock, strawberry, wild_1) and it just became…a Dracula. How boring. (props to @deithy for finding this cat)

When Stitches the fancy zombie cat appeared and we hashed out his recipe, we discovered something interesting. Check this out:

fancy chart stitches dracula

Look! It’s possible to have a cat with ALL the traits necessary for BOTH Stitches and Dracula. WHAT DOES THIS MEAN?! Which fancy would you get?

To know for sure, someone’s going to have to do it. (Chop, chop, breeders, let’s go.)

But in the meantime, let’s speculate. I think that if a cat were bred with all the traits for Dracula AND all the traits for Stitches, it would unlock a TIER-2 FANCY. It would be neither Dracula nor Stitches, but an entirely new fancy altogether. It would be incredibly rare because it would require 8 specific traits(!). And maybe it would be somehow related to the two fancy cats that went into it (Zombie + Vampire = Frankenstein Cat?).

Anyway, someone should definitely do it. The ultimate undead cat awaits.

Happy Breeding!

How to Make Fancy Cats

Some CryptoKitties are classified as Fancy cats. Their artwork differs from the standard set of cattributes. After a fancy cat is unlocked/discovered, you can breed your own by combining certain cattributes until the limit is reached. (Exclusive cats like Genesis cannot be reproduced through breeding.)

Fancy Cat Recipes and Limits

Vernon (320) = amur + springcrocus + fabulous + belleblue + cottoncandy + soserious
Berry (200) = dragonfruit + apricot + thunderstruck + emeraldgreen + simple
PussForProgress (1920) = himalayan + safetyvest + peach + gerbil
FortuneCat (888) = calicool + sapphire + harbourfog + swampgreen + beard
LionDance (888) = manx + googly + royalblue + starstruck
DogCat (88) = tigerpunk + sweetmeloncakes +barkbrown + periwinkle + yokel
Tabby (250) = ragamuffin + otaku + morningglory + cheeky
YuriCatsuki (250) = elk + tiger + cymric + neckbeard
MisterPurrfect (1,000) = strawberry + chocolate + wuvme + baddate
Earnie (500) = orangesoda + birman + grim + hotrod
Momo-chan (500) = onyx + henna + wolfgrey + sass + bloodred
Negato (500) = onyx + henna + wolfgrey + slyboots
Stitches (500) = hintomint + swampgreen + seafoam + saycheese
PhuZiqaat (1,000) = chartreux + spock + alien + pouty
SantaClaws (1,000) = cloudwhite + scarlet + beard + wild_d
Mistletoe (2,000) = crazy + oldlace + gerbil
Dracula (2,000) = laperm + spock + strawberry + wild_1
ShipCat (2,000)= sphynx + luckystripe + crazy + orangesoda
DuCat (10,000) = cymric + tongue

Purebred Cats

Before you read this post, make sure you know how to read a kitty’s genome.

Here’s what I think. Rarity in traits is fleeting. Alien eyes are valuable for like a day, and then everyone moves on to the next thing. But purebred cats–cats that have the same gene in D0,R1,R2,R3–will have rarity that lasts. They will have predictability: you KNOW what trait they will pass on. This predictability will come in handy when trying to create fancy cats.Read More »
