## Description

Breed calicoes, tortoiseshells, and ultra-rare coats using real cat genetics. Predict the odds with "What might be born?" - can you call the coat before it arrives?

"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 and fur length 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?
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, with the odds for each.
Read the parents' gene cards, work out which pairing gives you the coat you want, and go for it.
Every so often a mutation turns up that no prediction saw coming.

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 60 coats that are genetically possible are waiting to be found, and every undiscovered one comes with a hint. Go after the 6-star "legendary" cats by working out the right pairings.

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 19 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 screen, 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.)
