How to Value Your Kitties

New Tool: Kitty Evaluator

It’s impossible to put a specific price-tag on a kitty because its value is determined by the market, but it is possible to identify what elements of kitties hold more value than others. For example…

  • When all other things are equal, low generation cats are more valuable than high generation cats.
  • When all other things are equal, mutations are more valuable than basic traits.
  • When all other things are equal, pretty traits are more valuable than ugly ones.

These comparisons can help you know what to look for in a kitty.

The more of these components you have going for your kitty, the more valuable it will be. Low generation is easily the most important factor (if you intend to breed your kitties). If nothing else, PLEASE pay attention to generation.

But is there an easy way to evaluate your kitty’s traits? Why yes! So glad you asked!

Final Takeaway

The most valuable kitties are usually those with multiple mutations in low generations.

To maximize your odds of getting mutations, use the Mutation Match-Up Tool.

Discontinued Traits

sizzurp, luckystripe, chocolate, and kittencream have all been retired

Many players are unaware that cattributes are slowly being discontinued. These traits are no longer being released in Gen 0 cats, so the only way to get them is through cats that are already in existence. As time goes by, they will become more and more rare in low generation cats because they’ll be harder to produce (as the originator cats are likely Catatonic by now).

Not only will the discontinued traits become more rare, many of them will also be needed to create mutations with upcoming traits. For example, the eye color sizzurp is discontinued, but once the eye color with kai gene “5” is released, there will be a series of mutations that can happen only when combined with sizzurp. (To understand how mutations work, visit my post on Mutations and my post on All Possible Mutations.)

This might make sizzurp more valuable in low generations only.

In addition to being needed for mutations, discontinued traits will also likely be used in making fancies down the road. I personally think that as soon as new traits stop being released in Nov. 2018, the focus of the game will shift dramatically to fancies, fancies, fancies. If that happens, all these old traits will come into play in a much bigger way.

Here are the discontinued traits so far (to the best of my knowledge):

How do Family Jewels work?

There are two kinds of Family Jewels: Mew-tation jewels and Cattribute jewels.

family jewels 2

Mew-tation Jewelsfamily jewels 4

These jewels are awarded to the first 500 kitties who initiate bloodlines for a trait. They do this by being the first in their family tree to either a) carry a new basic trait, or b) mutate into a new trait. The first kitty with a new trait gets a spinning pink diamond and the next 499 get lesser jewels.

Cattribute Jewels

After the originator kitties claim their jewels, they get to pass them down to their descendants as cattribute jewels. Any descendant of an originator kitty receives the jewel if it also carries the trait. This means that jewels may skip certain kitties but then show up later in their children. Again, all descendants may claim their ancestor’s jewel as soon as they share the same trait. The descendants’ jewels will be the same color as their ancestor’s original jewel. (Note: I said “all descendants” but I’m a little unsure whether they continue indefinitely or not.)

Think of is this way. When CryptoKitties launched, the developers released 100 Founder Cats that were all jaguars. Since then, there have been no other kitties released with jaguar genes. That mean, whenever you see a cat with the jaguar pattern, you know immediately that it has a direct tie to one of the Founder Cats. Family jewels mimic this exactly. If you see a kitty with a pink diamond next to “cloudwhite”, you know that it has a direct link to the very first cloudwhite kitty.

You can click on a jeweled cattribute to see the originator kitty that it came from.

Example: fj kitty

This kitty was one of the first 500 kitties to unlock the pattern “camo”. All of its descendants may receive its blue camo jewel if they carry the camo gene.

This kitty is also a descendant of the very first “slyboots” kitty, and a descendant of one of the first 100 “thundergrey” kitties. Etc.

Will jewels make my kitty more valuable?

It’s hard to say right now because they’re so new. But I think it’s safe to say if there are two kitties with all other things equal, the kitty with more jewels will be valuable.

The mew-tation jewels will be more valuable than the cattribute jewels, and the most valuable jewel will easily be the pink diamond. The other jewels may end up as just eye candy, but the pink one will likely hold more significance.

Founder Badgesfounder badge

The Founder Cats did not get jewels, nor did their offspring. Poor jaguars. But the founders did get something else. They got badges. Aww.

What can I do with jewels?

You can collect them! If you breed jewel cats with other jewel cats, you can try to create kitties that have jewels next to ALL their cattributes. How fun would that be?!

Happy jewel collecting!

List of All Possible Mutations

Each trait has a “mutation pair” that, when bred together, has a small chance of mutating into a completely different gene. Here’s a guide on how to find all possible mutation combinations, even for non-visible genes and newly-released traits.

First, we need the Trait Chart. The Trait Chart shows all the discovered traits and their corresponding genetic codes. When a new trait is discovered, we simply look at the cat’s genes to see what code the new trait maps to.

Look at the chart. Do you see how the traits are divided into pairs? Each pair of neighboring genes can mutate.

What do they mutate to? Look at the right-hand column that says “mutates to”. It tells you what kai code the pair has potential to mutate into. For example, otaku+simple mutates to eye type ‘j‘, which is “fabulous” eyes.

trait chart explanation

When a new trait is released, you can immediately tell 1) what it will mutate with, and 2) where the new mutation will fall. For example, once we see eye type ‘1’ released, we know that you can breed it with “wonky” and that it will mutate into eye type ‘h’. AND THEN eye type ‘h’ can be bred with “alien” to mutate into eye type ‘q’. AND THEN eye type ‘q’ can be bred with “wingtips” to mutate into eye type ‘u’, which will be a tier-3 mutation!!

Ahhh. Beautiful, valuable mutation cascades. You gotta love ’em.

To learn more about mutations, visit THIS POST for a full explanation (including probabilites).

Also, to increase the value of your cats, try to stack mutations. Find a breeding partner for your kitty to maximize your odds by using this Mutation Match-Up tool.

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.


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, 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!

Original Artwork

There have been a few instances where the developers have changed the artwork on certain traits. It can be assumed that cats with the original artwork will never be able to be reproduced (which would make them more rare). Do you have an original?

Serpent – changed to have thicker eyelids.

  • Last kitty with original artwork: 456675
  • First kitty with new artwork: 456709

serpent artwork

Onyx – changed to have white whiskers instead of black.

  • Last kitty with original artwork: 478686
  • First kitty with new artwork: 478762

onyx artwork

Pouty – changed to have less of a smile.

  • Last kitty with original artwork: 478717
  • First kitty with new artwork: 478733

pouty artwork

Ganado – changed the side diamonds and chest diamond so their colors no longer match the side color and chest color.

  • Last kitty with original artwork: 483035
  • First kitty with new artwork: 483066

ganado artwork

Calicool – a change so minor, I’ll bet you’ll never see it. Go ahead, give it a try. I dare you.

  • Last kitty with original artwork: 44x,xxx?
  • First kitty with new artwork: 45x,xxx?
