Probably Stolen Rats: Feeding, Breeding and Care
Raise rats in an Animal Cage, keep suitable food available and watch hunger, health and crowding before trying to expand the colony. The official starting-scenario list includes Rat Wrangler, while the supplied recording shows rats as a separate business experiment rather than a guaranteed source of profit. The community husbandry reference provides the detailed breeding and care rules. It should not be confused with the aquarium system used for fish, even though both involve feeding and growth.
Begin with the right system
Rat Wrangler is one of the officially announced starts, but not every scenario begins with the same animal setup. The community starting-kit reference describes a cage, rats and supporting supplies for that particular route. A player arriving through another business needs to inspect what is actually available before copying a ready-equipped example. Owning a rat as an isolated inventory item is not the same operating situation as maintaining a functioning cage.
The supplied completion recording also moves between rats and fish, which its machine translation sometimes makes awkward to follow. Those observations should not be merged into a claim that a fish tank is the ordinary rat enclosure or that fish food is appropriate for every animal. The supplementary reference treats husbandry and aquaculture as separate systems. Identify which animal and equipment you are using before applying an instruction that only happens to mention feeding or breeding.
Establish a feeding routine
The husbandry reference describes hunger changing over nights and rats using food in the cage, including a dispenser where available. That makes feeding a continuing operating requirement rather than a single purchase that permanently solves the colony's needs. Check the current hunger state and the actual supply before ending the day. A cage containing something labelled as food is not enough evidence if the reference identifies that item as unsuitable for the animal.
The same source distinguishes appropriate inputs and warns about consequences from feeding rats their own meat. This page therefore does not recommend using every spare food item interchangeably or building a self-feeding loop from animal remains. The supplied video only observes the business and does not establish a tested universal diet. Use the item description and the cage's current contents instead of turning the player's experimentation into an unsupported feeding recipe.
Separate growth from breeding
The community reference distinguishes stages of growth and says breeding eligibility begins before the stage labelled adult. That is a reason to examine the actual animal's information instead of using one remembered age for every question. Growth, fertility and pregnancy are separate states in the reference, not different names for a single progress bar. A rat can therefore need one kind of attention for weight and another for reproduction.
The documented reproduction process also depends on the animals involved, rather than making every pair a guaranteed fixed nightly output. The reference describes fertility and a pregnancy period instead of an instant transformation when two rats share space. Do not count an expected litter as saleable inventory before it actually exists in the cage. Exact colony output for a particular set of genes and conditions remains Pending confirmation (待确认) unless the setup has been checked.
Keep health and cleanliness visible
The community husbandry page links poor conditions with disease risk and describes waste or dead animals as relevant to cage management. The supplied recording's uncertainty about collected droppings is not evidence that leaving them indefinitely is a profitable production rule. Cleanliness should be considered as part of animal care before treating every by-product as ordinary long-term storage. Check the state of the enclosure rather than judging it only by how many animals are present.
Crowding is another reason that expansion should be deliberate. More animals can create more management needs, and the reference describes harmful consequences when space is heavily occupied. This page does not invent a universal safe number of rats for every cage and arrangement. Use the actual enclosure and its condition information, and do not assume that a successful small colony can be scaled simply by adding every animal you find.
Understand what genes and tools change
The reference lists growth, hunger, fertility, immunity and longevity among the characteristics that affect care and reproduction. It also describes a Gene Scanner for examining inherited traits. That means a result from one animal is not automatically the result expected from every rat carrying the same species name. Check the information you can actually observe before blaming the enclosure for a difference associated with the animals themselves.
Specialised tools and serums have their own stated effects, so their existence is not a reason to improvise a universal improvement recipe. The supplied recording does not establish that every intervention raises every desirable characteristic at once. Treat any claimed trade-off according to the item description and do not invent a guaranteed best breeding line. If the relevant trait or effect cannot be verified, mark that conclusion Pending confirmation (待确认) rather than turning an appealing plan into a fact.
Turn output into a business deliberately
The official premise includes additional trades and crafting, and the community husbandry reference describes butchering rats into meat. The amount and form of output are linked to the animal's condition rather than a universal sale price per rat. A production step still needs an actual buyer and an operating plan, just as the supplied water-business recording needs more than a working machine. Do not confuse an inventory value with money already available for rent.
The completion recording shows rat raising as one of several experiments during a difficult run, not a controlled proof of maximum profitability. It provides no basis for an income guarantee, a fastest store-buyout schedule or a promise that neglecting care has no consequence. Start with a colony whose food, health and space you can track, then evaluate the output you actually obtain. Use the beginner guide for the cash routine and the guide directory for other trades without mixing their equipment rules into the cage.
Do not use one age for every milestone
The husbandry reference lists mating from three days old and an adult growth stage from five days old. Those are different milestones, so waiting for the adult label is not the same question as checking whether the animal can participate in breeding. The same reference describes pregnancy lasting three nights rather than immediate offspring after a pairing. Keep the animal's age, breeding state and the passage of nights separate when deciding what result to expect next.
These are documented baseline milestones, not a promise of identical growth, fertility or survival for every rat. Hunger, health and inherited characteristics also appear in the reference and should remain part of the observation. A delayed result therefore needs a check of the animal's current condition before you infer a new species rule or declare the cage broken. Record which milestone you were testing and what the animal actually showed, rather than reducing the whole system to one remembered number from a guide.
