This Mewgenics Breeding Guide details all the tips and tricks you need to breed so you have a better future cat. Breeding is one of the most important systems in Mewgenics, as is fighting. Winning fights during a run is great, but building stronger generations of cats is what really pushes your progress forward. If you want better stats and abilities than the average stray, you need to understand how breeding works and how to control it.
Breeding Guide – Mewgenics
At the beginning of the game, you won’t see all the important details about your cats. That is why sending 10 kittens to Tink early is extremely important. Doing this unlocks helpful information in batches like base stats, relationships, mood, libido, sexuality, and whether a cat is inbred.
Before you get serious about breeding, you need to understand what the stats and the symbols associated with them in your House mean. Each one affects how your cats grow, live, and pass down their traits.
- Comfort – It is represented by a sleeping icon and shows how relaxed your cats are. When cats have enough space and furniture, breeding becomes easier. You can raise Comfort by placing more furniture or spreading cats into different rooms.
- Stimulation – It is represented by yarn and measures how interesting the environment is for your cats. Adding furniture increases this. The higher your stimulation, the better the chances that strong base stats and useful abilities from parents will pass on to their kittens.
- Health – A medicine icon represents it and affects sickness and recovery. If Health is high, cats can heal wounds or diseases at the end of the day. If it is low, diseases are more likely. You can improve Health by cleaning poop, removing dead cats, and buying certain furniture. If you keep your House clean, you don’t need to focus too much on this stat.
- Mutation – A DNA symbol represents it and increases the odds of mutation/random genetic changes happening. Some furniture boosts this.
- Appeal – A House symbol represents it and represents the overall quality of your House. Raising Appeal improves the strength of the stray cats that visit.
You can improve your knowledge of breeding by sending kittens to Tink through the green pipe. Only base stats are passed to the next generation. A cat that became strong during adventures may still have weak base stats. For breeding purposes, base numbers matter much more than temporary power.
Be Selective with Your Cats
Not every cat deserves a place in your House. If a kitten does not stand out, it is usually better to send it away.
A simple rule: if a cat doesn’t have at least one stat at 6 or higher, it probably isn’t worth keeping. Later in the game, you can raise your standards and only keep cats with multiple good stats or at least one 7.
Trying to pass down specific abilities is difficult and unreliable. Instead of chasing certain traits, it is usually smarter to focus on high base stats.
Place cats with strong base numbers into the same room. This increases your chances of producing kittens with better overall stats. Grouping your strongest cats also makes it easier to manage class collars and build future roles more efficiently.
Weak kittens can be sent to Tink for research or saved if an NPC needs them.
Special Case: Gay Cats
Cats that are gay will not produce kittens. However, when they breed, they increase the chances of gay strays appearing in future days. These strays can inherit some of their stats and abilities.
While they won’t directly produce offspring in your house, they still influence the overall gene pool.
Focus on Appeal First
Furniture is bought weekly from Baby Jack. If you can afford it, buying everything helps overall growth. But early on, money can be tight.
In that case, focus on raising Appeal first. Higher Appeal means better strays will show up at your door. Without improving this, you may get stuck breeding average cats again and again.
After the Appeal, focus on Comfort so breeding happens more often. Stimulation should be strong so that abilities and stats pass down more reliably. Health can stay low if you keep things clean. Mutation is useful, but furniture for it appears less often, and it introduces randomness.
If your goal is steady improvement through breeding, Appeal, Comfort, and Stimulation are your main priorities.
How Breeding Happens
At the end of each day, cats in the same room can interact. Sometimes they fight, and sometimes they breed. If breeding happens, one or two kittens may be born. Newborn kittens cannot go on adventures right away, and they need at least one full day to grow up.
In the very early game, you only have one room. This makes breeding mostly random and harder to control. It also increases the risk of inbreeding, since all cats share the same space.
Use Separate Rooms Smartly
After donating a cat to Frank, you unlock the attic as a second room. The third room takes much longer to get, so for a while, you will only have two spaces.
Use this wisely. Keep your strongest breeding pairs in the main room with the best furniture and conditions. Move weaker cats and growing kittens to the attic. Combat-focused cats that became strong through leveling but have poor base stats are better kept away from your breeding area. This way, your best genes stay in a controlled space.
Avoid Inbreeding
Try not to keep closely related cats in the same room by checking their family tree. Breeding within the same family causes weaker, uglier offspring and stronger penalties over time. Birth defects become more common, and overall stats suffer.
If a cat has defects or clear problems, consider sending it to Tink or to Dr. Beanies.
Turning Catfights into an Advantage
Fights between cats might seem like a problem at first, but they can actually be used to your benefit.
Cats may start fighting for several reasons. Low Comfort in a room is one of the main triggers. High Aggression in certain cats can also lead to conflict. Rivalries form as well, for example, if two cats are partners and a third cat tries to interfere, that jealousy can quickly turn into a fight.
Of course, fights come with risks. Cats can get injured, and in some cases, they may even die. However, the winner doesn’t walk away empty-handed. Victorious cats gain a random stat increase, which makes them stronger over time.
If you have unlocked an extra room, you can take advantage of this system. Instead of keeping all cats in comfortable conditions, you can dedicate one room to fighting. Lower the Comfort by adjusting furniture and place your more average or less valuable cats there. Eventually, a few survivors will collect enough stat boosts to become solid fighters.
Value Good Mutations
Normally, base stats remain 7. However, mutations can push stats even further. Always check what a mutation gives and what it takes away. If a mutation has no downside, that cat is extremely valuable. Even if there is a penalty, it might not matter depending on how you use the cat.
For example, a mutation that adds Constitution but reduces Dexterity is great for close-range roles like Fighters or Tanks. If the drawback does not affect the cat’s intended job, it’s often worth keeping.
Smart Furniture Management
You can get furniture from Baby Jack or by bringing back Furniture Boxes from runs. Be careful with Furniture Boxes; if you equip them for their armour bonus and they break during combat, you will lose the furniture inside and won’t receive it at home.
