What to know
-
Tink upgrades are information unlocks that expose hidden cat stats and relationship signals used for breeding decisions.
-
You level Tink by donating kittens (typically the ones with weak stats, bad traits, or no valuable skills).
-
The information you unlock includes indicators like aggression, libido, inbred info, and sexual orientation, plus how cats feel about specific housemates.
-
After you finish all of Tink’s upgrades, additional kitten donations convert into a simple coin reward.
In Mewgenics, you should look to get Tink leveled early because his upgrades are all about revealing hidden breeding and relationship info, which makes pairing cats (and planning a bloodline) much less guessy. Tink only accepts kittens, so you can progress his upgrade track steadily while your best adults keep running zones.
| Upgrade theme | What it adds | How it helps |
|---|---|---|
| Breeding-related insights | More visible information about your cats for breeding decisions | Helps you stop wasting cycles on incompatible pairs and improves long-term planning |
| Aggression indicator | A way to see aggression as a marker | Helps you avoid pairing (or rooming) cats that will constantly clash |
| Libido indicator | A way to see libido as a marker | Helps you understand why breeding attempts stall even when everything else looks fine |
| Sexual orientation indicator | A way to see sexual orientation as a marker | Helps explain non-breeding outcomes caused by same-sex pairing |
| Like/dislike signals | Shows whether cats like or dislike certain cats in your home | Helps you manage pairings and reduce friction in your house dynamics |
| Inbred indicator | Shows whether a cat is not inbred, slightly inbred, or moderately inbred | Helps you avoid increased birth-defect risk from repeated close-family breeding |
| Post-max reward | Extra reward after you exhaust all upgrades | Turns spare kittens into a consistent resource |
How to unlock and level Tink upgrades
Tink’s requirement is straightforward: he wants kittens, which is why his track is considered one of the easiest to push compared to NPCs that require zone progress, injuries, or specific conditions.

Step 1
Breed regularly and decide up front that some kittens are information fuel, not future adventurers.
Step 2
When a kitten is mediocre (weak stats, poor traits, or no class-specific skills), send it to Tink instead of trying to force it into your main line.

Step 3
Keep donating kittens as you play so new layers of breeding-related info unlock as early as possible.

Step 4
Once you have exhausted all of Tink’s upgrades, continue donating only if you want the repeatable coin payout that replaces further upgrades.
All Tink upgrade unlocks and what they do
This is the full set of Tink-related information unlocks grouped by what they reveal and how to use it in practice.
Aggression visibility
Tink eventually reveals an aggression indicator for your cats. Use it to avoid housing or pairing cats likely to create conflict-heavy dynamics, especially when you are trying to keep breeding consistent instead of chaotic.
Inbred visibility

Tink also unlocks an inbred indicator, which lets you see whether a cat is not inbred, slightly inbred, or moderately inbred. This matters because inbreeding increases the chance of harmful birth defects, so the indicator helps you avoid repeating risky pairings for too many generations.
Libido visibility

Tink eventually reveals a libido indicator for your cats. Use it when you are stuck in a loop of failed breeding attempts and need a quick sanity check on whether the pairing has the drive to produce kittens on your schedule.
Sexual orientation visibility
Tink eventually reveals an indicator for sexual orientation. Use it to immediately identify cases where you are attempting to breed a same-sex pairing and wondering why nothing is happening.
Like and dislike visibility
Tink eventually reveals whether cats like or dislike certain other cats in your home.

Use it to plan who shares rooms and who you attempt to pair, since consistent friction can derail the stable setup you want for a focused breeding program.
What happens after you max Tink
After all of Tink’s upgrades are exhausted, continued kitten donations reward you with +100 coins.

Rewards & Milestones
| Milestone | Reward |
|---|---|
| Progressing Tink’s upgrade track | Breeding-related insights, including indicators for aggression, libido, sexual orientation, and like/dislike info about housemates |
| After all Tink upgrades are exhausted | +100 coins per additional kitten donation |
How to choose which kittens to donate
The cleanest rule is to donate kittens you would never build a run around, because Tink’s information upgrades are permanent value, while a bad kitten is usually temporary clutter. Donate kittens with mediocre stats, undesirable traits, or no class-specific skills so you can unlock the breeding intel sooner.
If your goal is better breeding outcomes with fewer wasted days, Tink’s upgrades are the most direct path because they turn hidden compatibility and temperament factors into visible, actionable info. Once you have them all, Tink becomes a steady way to convert spare kittens into coins while your best cats carry your runs.
