## What is Cat Genetics Lab?

"What kind of kitten will we get next?"

Cat Genetics Lab is a breeding simulation built on the real rules of cat genetics.

REAL HEREDITY
Coat colour, pattern, white markings, fur length, colourpoint and dominant white all pass from parent to kitten exactly as they do in real cats.
- Why are calico and tortoiseshell cats almost always female?
- How can two black cats have a grey kitten?
- How can one gene hide every other coat a cat is carrying?
You pick the answers up naturally, just by playing.

PREDICT, BREED, CHECK YOUR ANSWER
Choose two cats and the prediction strip shows every coat their kitten could have.
Call your shot - say which coat will be born. Get it right and the kitten grows up twice as fast. Get it wrong and the odds stay hidden for your next breeding, so it pays to read the genes rather than guess.
Every so often a mutation turns up that no prediction saw coming.

DEDUCTION MODE
Recessive genes a cat is hiding show up as "?". The moment a dilute, solid, longhaired or colourpoint kitten is born, the parents' hidden genes are revealed - the same test cross a real geneticist would use.

HOW TO PLAY
1. Pick two cats and predict what will be born
2. Breed them, and see the kitten's coat
3. A rare coat earns a new entry in your collection
4. Kittens grow up in 30 minutes (you get a notification), then they can breed too

COMPLETE THE COLLECTION
All 122 coats that are genetically possible are waiting to be found, and every undiscovered one comes with a hint. Townspeople send requests you can fill for rewards, and the Foster Board lets you take in a cat whose genes you can see before you decide. Finish the collection and start a new lab, keeping your records and achievements.

SEE WHY THE ODDS ARE WHAT THEY ARE
Tap any item in the prediction strip to open a Punnett square for each gene, so you can follow the maths behind the percentage. There's also a family tree going back to the grandparents, and a records screen with lifetime stats and 23 achievements - plenty to do after the collection is full.

YOU MIGHT LIKE THIS IF
- You like cats
- You like filling in collections
- You've lost time to breeding systems in other games
- You're a bit curious about how heredity works

Free to play, at your own pace.
(A banner ad sits at the bottom of the catalog tab, and a full-screen ad appears now and then while breeding. A one-time purchase removes both. Reward ads are always your choice to watch. There is also a Decoration Pack that only changes how things look - it never changes how the game plays.)


## Version history (last 5 releases)

### 1.10 — 2026-09-28

Two daily challenges, and more ways to read the genetics.

- Today's Quiz: three questions picked by the date (probability, pick-the-pair, deduction). Everyone solves the same set that day. The answer screen opens the Punnett square so you can see why, and a perfect day earns an Advice Ticket. Share your result as emoji.
- Cat Show: match the day's theme and the judge's taste, and enter one of your cats each day. Win and you get a Grow Ticket, plus a ribbon next to that cat's name.
- Twins: sometimes two kittens are born at once. Two different coats from the same parents show what "inherited independently" really means. Your prediction counts if either one hits.
- Inbreeding: the closer the pair, the more likely a mutation (about 4x for the closest pairs). In exchange the kitten takes longer to grow up. You see this before you breed.
- Test cross: what did not appear is a clue too. Every kitten without the recessive coat raises the odds that the parent is not hiding that gene, right on the gene card.
- The collection now shows who found each coat and when, and the tab gets a red dot for new finds.
- Fixed: the breed button could stop responding, Grow Tickets could disappear, and twins completing two requests at once only showed one thank-you.

### 1.7 — 2026-09-24

The collection grew to 122 coats, and you can now deduce the genes your cats are hiding.

NEW GENES
- Colourpoint: colour only on the face and ears, like a Siamese.
- Dominant white: one copy hides every other coat a cat is carrying.
- The collection went from 60 coats to 122.

PREDICTION IS NOW A MOVE YOU MAKE
- Call which coat will be born. Get it right and the kitten grows up twice as fast.
- Get it wrong and the odds stay hidden for your next breeding, so read the genes rather than guess.

DEDUCTION MODE
- Recessive genes a cat is hiding show up as "?".
- A dilute, solid, longhaired or colourpoint kitten reveals what its parents were carrying.
- Can be turned off in Settings.

REQUESTS FROM TOWN
- Fill a request for Grow Tickets, DNA Kits or a visiting stray.
- Spend an Advice Ticket to be told which pairing to try.

FOSTER BOARD
- Take in a cat looking for a home with Grow Tickets.
- You can see which genes it carries before you decide.

A NEW LAB
- Finish the collection and start over, keeping your records and achievements.
- Four different starter cats every time, a little harder each round.

ALSO
- Added a Decoration Pack: 10 collar colours and 4 lab backgrounds, cosmetic only.
- Fixed lifetime records being lost when starting a new lab, and white cats showing a 0% appearance rate.

### 1.3 — 2026-09-18

Version 1.2 could erase your cats and collection when you updated.
We're sorry for the trouble - this is fixed in 1.3.

Also in this update:
- Six more languages (English, German, Spanish, French, Korean, Chinese)
- Remove ads: a one-time purchase that clears the banner and full-screen ads
- Reward ads: watch one to grow a kitten up instantly, or raise your cat limit (up to +5)
- Day streaks, and six new achievements for 19 in total
- Share your completed collection as a single card
- Rebuilt breeding screen: about three times as many cats visible in the list

### 1.1 — 2026-09-08

英語に対応しました。そのほか、遊びを深める4つの追加です。

・確率のしくみ（パネット方形）: 「うまれるかも？」の項目をタップすると、遺伝子ごとの掛け合わせ表で「なぜその確率になるのか」を目で確かめられます
・家系図: ねこの詳細から、親・祖父母までさかのぼって血すじをたどれます（里親に出した親の記録も残ります）
