How do Family Jewels work?

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

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!

Undiscovered Fancies – Hints and Speculation

Update: Earnie (the Golden Kitty Fancy) does NOT require gold. Details below.

There are a lot of fancies waiting to be discovered right now. Here’s what we think we know. (Remember: before going after a fancy combo, make sure no kitties already exist with that combo.)

Golden Kitty Fancy (Earnie)earnie.jpg

  • Named in honor of for winning the Product Hunt Golden Kitty Award (CryptoKitties was a nominee for the award).
  • Released around Feb. 1.
  • Twitter hint #1: “Their favorite drink is neither Coke nor Pepsi.” This probably means that orangesoda is a required trait, although it’s possible it could be referring to lemonade (or both).
  • Twitter hint #2: “They picked up this cattribute on a trip to Burma…” This is referring to the cattribute birman (confirmed by the developers on Twitter).
  • Twitter hint #3: “Earnie has a favorite kind of fairy tail…” This is probably referring to grim.
  • Twitter hint #3.5: “Trying to breed Earnie with a cattribute as literal as this one is a fool’s errand…” This means that gold (eye color) is NOT a required cattribute in the Earnie formula.
  • Earnie has 4 traits. (According to the CK developers on Twitter.)
  • Earnie = orangesoda + birman + grim + gold + (lemonade(?), daffodil(?), …?)
earnie 2
Don’t I look like a Golden Kitty?


Good Fortune Kitty (Maneki-Neko)Fortune Kitty

  • Unconfirmed fancy from a leaked image from a meet-up in Hong Kong.
  • Guesses from the image: wingtips, calicool, soserious, topaz/forgetmenot/sapphire, bobtail
  • From the Wikipedia page about Maneki-Neko (lucky kitties), it says that they’re most commonly white. So cloudwhite is likely part of the formula as well.
  • Note: Most fancies have 4-trait requirements. And some fancies exhibit traits that aren’t part of their formulas (e.g. SantaClaws has cheeky), and vice versa.
  • Maneki-Neko = wingtips(?) + calicool(?) + cloudwhite(?) + bobtail(?) + soserious(?) + topaz/forgetmenot/sapphire(?) + …?

Lion-Dance Kitty (Chinese Fancy #2)

  • According to a Quartz article about the CryptoKitties launch in China, there will be three fancies released during the Lunar New Year holiday season, and one of those will be kitty dressed in a lion-dance costume.

Chinese Fancy #3

  • See above comment.

Chinese Golden Dragon Exclusive Kitty

  • According to the same Quartz article, there will also be an exclusive kitty that resembles a golden dragon. Since it will be an exclusive fancy kitty, it will not have a recipe and will not be able to be created.

Year of the Dog Kitty (Exclusive?)dog kitty

  • This dog kitty is most likely an exclusive kitty (cannot be reproduced). In other words, it probably doesn’t have a “recipe”.
  • We know it exists based on this image and message from Benny: “We’ve announced our partnership with Cobo for the Chinese New Year launch. We will be doing a co-marketing campaign with the top prize being one of the most coveted kitties. A symbol for the year of the dog!”

Draco (Dragon Kitty)draco

  • May or may not be released yet.
  • No hints have been given out, no traits have been confirmed. The formula pieces below are pure guesses.
  • Draco = wuvme(?) + verdigris(?) + googly(?) + spangled(?) + elk(?) + …?

 Korean Fancy

  • Unconfirmed, but since there have been fancies for Japan (ninjas) and fancies for China (see above), we can assume that South Korea will get some too.

Valentine’s Day Fancy (Love Kitty)

  • Unconfirmed, but there are usually fancies for all the major holidays.
  • Love Kitty = wuvme(?) + chocolate(?) + strawberry(?) + …?

Weekly 411 – Week 2 (2/1/18)

New Traits
1/30: twilightsparkle (eye color, mutation of forgetmenot and sapphire)
1/30: forgetmenot (eye color)
1/30: norwegianforest (body type)
1/30: savannah (body type)

New Fancies
1/31: Momo-chan (Ninja Fancy)
1/29: Negato the Ninja (Ninja Fancy)


  • Word on the street is that there will be fancies released for each new region CryptoKitties is launching into this month. Ninjas for Japan, something for China / HK (maybe a Fortune Cat?), and something for South Korea (I hope it’s a K-Pop Kitty!).
  • Speaking of fancies, we know there’s a Golden Kitty fancy waiting to be discovered (probably needs gold eyes).
  • It’s also likely that there will be a Valentine’s Day fancy released before Feb. 14.
  • “Family jewels” (enhanced cattributes) are supposed to arrive this week. Hmm…where are they? Speculation is that they may have something do to with “first-of-their-kind” cats. The developers suggested that they might apply to you if you were “one of the first to discover a new cattribute these past few weeks”.
  • Now that the China launch is just around the corner, players are starting to pay attention to the Chinese numerology of Kitty #s. In particular, players are looking for kitties with several 8’s in a row. In Chinese, the word for 8 (ba) sounds very similar to the word for wealth (fa), so several 8’s together (8888) suggests that you may be very lucky and prosperous. To learn more about Chinese numerology, look HERE.
  • Something is going to happen when we hit 500,000 kitties. According to this tweet, Kitty #500000 may look something like this:kitty 500k


  • The first Kitty Battle is happening now! The winner of the Kitty Battle contest will receive an exclusive Kitty411 Gold Medal, a free kitty, and a limited-edition kitty football helmet. For details (and to enter your kitty), visit the CONTEST page.

  • CryptoKitties developers keeping dropping hints on Twitter about undiscovered fancies. Players are speculating that there might be a Teenage Mutant Ninja Turtle Fancy waiting to be discovered (see this tweet). Some players are convinced that “turtleback” would be a needed trait for a ninja (turtle?) kitty.
  • There’s also speculation that there’s an undiscovered fancy that uses “onyx” (see this tweet). (Either the same or different fancy as the turtleback one.)
  • Aaaaand also “henna“. (See tweet here.)


  • The artwork for “onyx”, “pouty”, and “ganado” was changed. Onyx now has white whiskers instead of black, pouty now has less of a smile, and ganado’s side and chest diamonds no longer match the side and chest color, respectively. See the Original Artwork post for pictures and details.
  • The developers said that their Twitter polls give out hints about undiscovered Fancy Cats.
  • Mark Flavelle (co-founder) had an AMA on Token Daily.
  • CryptoKitties was nominated for a Golden Kitty Award from Product Hunt. The developers suggested that they will release a “golden kitty” fancy if they win the award. Go here to vote.
  • Family Jewels, or “enhanced cattributes”, are coming next week. I wonder what that means!

A DOUBLE Fancy?!

Related post: How to Make Fancy Cats.

UPDATE: Bad news, guys, there’s no double fancy. *weep* Check out this cat: 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!

The Future is Meow.

One thing that’s cool about CryptoKitties is that they’re a real blockchain asset, 100% owned by you. Once you buy a kitty, it cannot be taken from you or destroyed. Your kitty belongs to YOU.

That means you can do whatever you want with your kitties, whether it be within the CryptoKitty interface or in another environment altogether. As third parties develop new ways to play with the kitties, the possibilities explode.
