Probably Stolen Rats Guide: Breeding, Care, and Meat Production
Master rodent ranching in Probably Stolen. Learn breeding cycles, cage management, feeding mechanics, and how to butcher rats for massive meat profits.
Surviving the brutal weekly rent escalations on a dystopian orbital station demands high-margin enterprise, and farming Probably Stolen rats has quickly become the ultimate survival strategy for indie shopkeepers. Instead of relying purely on scavenged junk and stolen meds, mastering Probably Stolen rats provides a continuous stream of protein for the station's starving lower decks. Whether you picked the Rat Wrangler origin or transitioned into animal husbandry through black-market favors, breeding rodents turns modest nutrient tubers into credits.
This comprehensive guide covers everything from reproductive mechanics and disease mitigation to butchering yields and optimal shop display setups.
Unlocking the Rat Wrangler Scenario and Starting Kit
Following the 48.3.12 patch for Probably Stolen on Steam, the previously unlisted "Rat Wrangler" scenario is now fully selectable from the main menu. Choosing this origin sets your shopkeeper up with the fundamental tools of animal husbandry right on Day 1, bypassing the need to unlock initial blueprints through Joe Wild.
When launching a Rat Wrangler playthrough, you begin with a specialized animal cage, a starter colony of rodents, feeding supplies, and a butchering cleaver.
Starter Kit Contents:
- 1x Small Animal Wire Cage
- 4x Mature Adult Rats (mixed male and female)
- 2x Juvenile Rat Pups
- 1x Butcher's Cleaver
- 1x Livestock Immunity Serum
- Small Nutri Feed Chunks
Selecting perks that complement this lifestyle makes an enormous difference. Player experience reveals that taking the "Bad Lease" negative perk (+40 credits weekly base rent) can be safely offset by picking upfront credit bonuses like "Savings" or reputation boosts like "Well Connected." The early cash influx lets you acquire vital storage infrastructure, such as a Smuggler's Bay from Dr. Jackson, keeping unauthorized livestock out of sight during surprise security checks.
| Starter Item / Asset | Primary Purpose | Base Durability / Usage |
|---|---|---|
| Small Animal Cage | Houses up to 6–8 rodents before overcrowding occurs | Requires scrap metal to repair |
| Butcher's Cleaver | Converts mature rodents into raw meat and morsels | Indefinite (standard tool) |
| Nutri Feed Chunks | High-calorie, seedless tuber rations for livestock | Single-use consumable |
| Livestock Immunity Serum | Boosts animal disease resistance at the cost of hunger | Single-use injectable |
| Starting Capital (Base) | Used to purchase machinery and feed reserves | 750–900 credits (perk dependent) |
Breeding Mechanics and Lifecycle of Probably Stolen Rats
Success when cultivating Probably Stolen rats hinges on understanding the hidden biological stats under the hood. Every rodent in your colony possesses dedicated metrics: weight (measured in grams), hunger rate, immunity, fertility, and health.
The reproductive cycle of Probably Stolen rats requires at least one healthy mature male and one non-pregnant adult female sharing the same cage. Once impregnated, female rats enter a short gestation cycle lasting approximately two days before delivering litters of small pups weighing roughly 45 to 55 grams.
Life Cycle Progression:
Rat Pup (45–55g) ➔ Adolescent Rat (120–190g) ➔ Mature Adult Rat (275–385g+)
Managing cage capacity is critical. When the rodent count exceeds the physical limits of your cage, an "Overcrowding" debuff triggers. Community reports confirm that overcrowding drastically tanks colony fertility, elevates stress, and accelerates disease outbreaks.
To maintain peak breeding velocity, keep a strict gender ratio of roughly one male for every three or four females. Excess males should be isolated and processed for meat immediately to preserve space for pregnant females.
| Rodent Growth Stage | Typical Weight Range | Time to Next Stage | Recommended Action |
|---|---|---|---|
| Newborn Pup | 45g – 60g | 1 – 2 Days | Leave in cage; ensure ample feed access |
| Adolescent | 120g – 200g | 1 – 2 Days | Monitor sex; administer growth serum if needed |
| Adult Female | 270g – 380g | Terminal (Breeding) | Keep paired with a male; monitor pregnancy status |
| Adult Male | 300g – 390g+ | Terminal (Breeding) | Retain 1–2 for studding; butcher excess males |
| Diseased Adult | Any Weight | Terminal (Declining) | Isolate immediately or butcher to stop contamination |
Nutrition, Disease Prevention, and Cage Maintenance
Keeping your Probably Stolen rats healthy requires balanced feeding and meticulous sanitation. Rats cannot survive indefinitely on cage air; starved animals will stop gaining weight, lose fertility, and eventually succumb to wasting disease.
The standard diet consists of "Nutri" tubers—mass-produced, pest-resistant crops developed by the station's Pasteline Corporation. While whole Nutri roots are too bulky for cage slots, small Nutri pieces and processed fruitlets provide ideal caloric density.
Sanitation is just as vital as food. Every night, active cages generate animal feces. If you leave droppings inside the habitat across multiple day cycles, the disease risk multiplies. Once a rodent contracts an infection, its max health drops steadily, threatening the entire pen.
Daily Rodent Care Routine:
1. Open cage interface each morning.
2. Remove and discard animal feces immediately.
3. Check rat hunger gauges and insert Nutri fruitlets or chopped produce.
4. Verify pregnant females are nourished.
5. Apply Livestock Immunity Serum if colony immunity dips below safe thresholds.
| Feed & Medical Item | Source / Vendor | Primary Effect | Downsides / Trade-offs |
|---|---|---|---|
| Nutri Fruitlets | Weekly Rat Wrangler | Efficient baseline caloric sustenance | Must buy in bulk during vendor visits |
| Dairy / Cheese Scraps | Scavengers / Food Sellers | High nutritional value, eaten greedily | Expensive on open market; larger rats hog it |
| Immunity Serum | Specialty Vendors | Drastically raises disease resistance | Temporarily increases rat hunger consumption |
| Steroid Serum | Specialty Vendors | Accelerates daily weight gain | Lowers base immunity; spikes hunger rates |
| Cleaner Robot | Late-Tier Hardware | Automatically cleans feces nightly | Requires power grid connection and maintenance |
Butchering and Turning Probably Stolen Rats into High-Margin Meat
Slaughtering Probably Stolen rats at peak weight is where your labor translates into raw economic leverage. When an adult rat hits 350 grams or higher, keeping it alive burns feed without adding significant value. Using your cleaver on a fully grown rodent breaks it down into multiple cuts of butcher-grade meat.
Butchering Yields (Adult Rat ~360g–385g):
- 1x Small Piece of Raw Meat (High base value: ~90–120 credits)
- 1x Medium Raw Morsel (~40–60 credits)
- 1–2x Small Morsels (~15–25 credits each)
Timing your meat sales is just as crucial as slaughter weight. Random station events frequently disrupt market dynamics. For instance, when the station bulletin reports a "Poor Nutri Harvest," all raw food and protein prices surge by 20% to 40%. Stockpiling raw rat meat in a refrigerated Smuggler's Bay during normal days and dumping your inventory during crop shortages produces astronomical profits.
| Harvested Meat Cut | Average Sell Price | Preferred Customer Archetype | Optimal Display Strategy |
|---|---|---|---|
| Raw Meat Cut | 90 – 140 Credits | Street Chefs, Upper-Level Souvenir Buyers | Place in primary showcase window |
| Medium Morsel | 45 – 75 Credits | Hungry Citizens, Laborers | Package alongside basic commodities |
| Small Morsel | 18 – 30 Credits | Low-budget Beggars, Desperate Citizens | Use as budget filler to empty wallets |
| Packaged Ration | 150 – 210 Credits | Mining Expeditions, Mercenaries | Requires crafting module (Junk Processor) |
Expanding Your Rodent Empire: Essential Upgrades & Vendors
To sustain an expanding rodent operation, you must outgrow the basic cage quickly. The weekly visiting Rat Wrangler merchant is your primary partner for specialty livestock equipment. She carries spare animal pens, genetic scanners (to inspect growth multipliers), automated feed dispensers, and concentrated serums.

Frequently Asked Questions About Probably Stolen Rats
Can I feed Probably Stolen rats their own butchered meat?
While the game's inventory interface allows you to drop raw meat items into the habitat, community reports strongly advise against cannibalistic feeding. Feeding rodents their own flesh can trigger severe disease conditions, ruining the reproductive fertility of your breeding stock. Stick to vegetable-based Nutri products and commercial grain pellets.
How do I stop Probably Stolen rats from contracting disease?
Disease outbreaks are caused by two primary factors: accumulated feces and severe overcrowding. To maintain a sterile environment, manually remove animal waste from the pen every morning. If an outbreak occurs, administer a dose of Livestock Immunity Serum to your breeding females and immediately cull any diseased non-breeders.
What is the ideal male-to-female ratio for breeding Probably Stolen rats?
Keep one virile adult male for every three or four adult females. A single male can impregnate multiple females within a couple of cycles. Storing excess males in a single cage wastes precious feed, accelerates overcrowding penalties, and cuts into your meat production throughput.
How do I upgrade my starting animal cage capacity?
To expand the small starter cage, you need metal ingots rather than basic scrap. You can purchase ingots occasionally from visiting metal scavengers or construct an electric furnace module from Dr. Jackson to refine raw station scrap into structural ingots. Each ingot upgrade raises the maximum capacity, allowing larger litters to mature safely.
