If I find an injured wild animal, can I keep it at home and look after it for a while?

No. What the original text describes is "temporary holding" rather than keeping: a quiet, dark, warm, well-ventilated cardboard box or covered container, lined with a towel rather than fabric that can entangle, with no water bowl and no food, kept away from human voices and from dogs and cats, contacting the local licensed wildlife rescue organisation or shelter as quickly as possible to hand the animal over, and not holding it oneself for longer than the necessary waiting time.

A wild animal looks docile and unafraid of people — does that mean it is friendly towards humans?

No, that is a warning sign. The original text states that a wild animal that "looks docile and is unafraid of people" is not being friendly; it may be ill (rabies, for instance, affects behaviour), injured and unable to flee, or already attached to humans (imprinting, which will make later release impossible); ordinary people should avoid initiating contact and avoid letting the animal become accustomed to humans.

Which zoonoses call for particular care when in contact with wildlife, zoo animals or working animals?

This article lists six: rabies (bites from wild mammals; once symptoms appear it is almost always fatal, and anyone bitten must seek medical care immediately for assessment of post-exposure prophylaxis), avian influenza (contact with sick or dead poultry or wild bird droppings; a notifiable public health event), tuberculosis (close contact between zoo keepers and large mammals), leptospirosis (water search-and-rescue dogs coming into contact with contaminated water or the urine of wild rodents), psittacosis (respiratory secretions of birds) and salmonella (reptiles; the risk is higher in children and the immunocompromised, and hands must be washed after contact).

What needs attention in the care of working animals after retirement?

The original text makes three points: after retirement activity drops sharply while the working-period ration is maintained, readily causing obesity and increased joint load, so the ration must be adjusted; the home environment must take account of age-related joint protection (non-slip flooring, gentle ramps instead of stairs); and the transition to retirement may bring difficulty adapting behaviourally, similar to role-transition anxiety, calling for a gradual reduction in workload rather than an abrupt stop to work.

Finding an injured or apparently abandoned wild animal and taking it home to keep, or feeding it whatever comes to hand — why does this go wrong?

Finding an injured or apparently abandoned wild animal and taking it home to keep, or feeding it whatever comes to hand. You do not know what it should really eat or how it should be cared for, and feeding the wrong thing is often worse than not feeding at all; the correct approach is to telephone the local licensed wildlife rescue organisation and let professionals handle it.

The eight columns of this chapter’s 12-column knowledge tree that have not been published separately, together with the chapter’s plain-language section on the five deadliest mistakes people make. Covers three subdomains — wildlife, zoo animals and working animals: the scope of this Tier, housing, nutrition and feeding, behaviour and welfare, preventive medicine, zoonoses, household toxins and hazards, geriatric care and euthanasia decisions, plus five mistakes that most often harm the animal. Species and lifespan, normal vital signs, common diseases and emergency red flags have each been published as separate articles and are not repeated here.

This content is compiled from the Wildlife and Working Animals chapter of the veterinary animal encyclopedia. The same sign calls for different handling in different species, and copying what is done for another species can be harmful — first confirm which animal you are dealing with.

This article collects the columns of this chapter's 12-column knowledge tree that have not yet been published as separate articles. The four columns on species and lifespan, normal vital signs, common diseases and emergency red flags have each been published as separate articles and are not repeated here.

0. Scope of this Tier (three sub-fields, different in nature, treated separately)

Sub-field	The ordinary person's role	The focus of this part
A. Wildlife	Not a keeper, merely a passer-by who happens to encounter／pick up the animal	"What not to do" ＋ how to hand over lawfully to a rescue organisation
B. Zoo Animals	Visitor／keeper／veterinarian, not a private owner	Herd medicine, quarantine, anaesthetic risk, visitor safety
C. Working Animals	User／employer／adopter after retirement	Occupational injury, transition to retirement, euthanasia decisions

In the 12 columns below, each column is split into A／B／C blocks as required; columns on which the original teaching material says nothing at all are marked directly as "not in the original material".

From the article text; read alongside the full article.

3. Housing (enclosure／water quality／temperature and humidity／lighting)

Sub-field	Environmental focus
A Wildlife	Temporary holding (not keeping) when an ordinary person picks up an injured wild animal: a quiet, dark, warm, well-ventilated cardboard box／covered container, lined with a towel rather than fabric that can entangle, with no water bowl／food, kept away from human voices and from dogs and cats, contacting the local licensed wildlife rescue organisation or shelter as quickly as possible to hand the animal over, and not holding it oneself for longer than the necessary waiting time
B Zoo	Species-appropriate space and environmental enrichment, quarantine isolation facilities (physical separation of newly arrived／sick animals from exhibit animals), double-barrier safety design between visitors and animals, biosecurity across enclosures (disinfection routes, no sharing of equipment)
C Working Animals	Kennels must match activity level and quality of rest; the home environment of a retired animal must take account of age-related joint protection (non-slip flooring, gentle ramps instead of stairs, the same principle as for older dogs in T1); working horses and mules need shelter and a dry environment for the feet (to prevent foot disease)

4. Nutrition and feeding (including what keepers most often feed wrongly)

Sub-field	Focus	Most common mistake
A Wildlife	An ordinary person should not feed a wild animal they have picked up — you do not know the species' true diet, and the wrong food can cause a gastrointestinal emergency or worsen shock; giving cow's milk／human infant formula to a young mammal by mistake can cause diarrhoea and even death	"It looks hungry so I fed it", "pouring milk into a baby bird/animal to save it"
B Zoo	Diet must be adjusted by a zoo nutritionist according to species, age and reproductive state, including feeding enrichment to reduce stereotypic behaviour	Visitor feeding (feeding in breach of the rules is one of the main causes of obesity, foreign-body obstruction and behavioural problems in zoos)
C Working Animals	Energy／electrolyte requirements rise during periods of heavy work; after retirement activity drops sharply while the working-period ration is maintained, readily causing obesity and increased joint load	Not adjusting the ration after retirement

5. Behaviour and welfare (normal behaviour, stress signals, the five welfare needs)

Sub-field	Focus
A Wildlife	A wild animal that "looks docile and is unafraid of people" is not being friendly, it is a warning sign — it may be ill (rabies, for instance, affects behaviour), injured and unable to flee, or already attached to humans (imprinting, which will make later release impossible); ordinary people should avoid initiating contact and avoid letting the animal become accustomed to humans
B Zoo	The five welfare needs (freedom from hunger and thirst, from discomfort, from pain, injury and disease, freedom to express normal behaviour, and freedom from fear and distress) are the basis of international zoo welfare assessment; stereotypic behaviour (pacing back and forth, over-grooming to the point of hair loss) is an observable red flag for poor welfare
C Working Animals	Signs of occupational burnout: avoidance of tasks the animal previously loved, declining work performance, irritability; the transition to retirement may bring anxiety-like signs, calling for a gradual reduction in workload rather than an abrupt stop to work

6. Preventive medicine (vaccination／deworming／neutering／frequency of health checks)

Sub-field	Focus
A Wildlife	This belongs to population-level public health management of wildlife (such as the distribution of oral rabies vaccine baits), not to the level of an individual animal's keeper, and ordinary people neither can nor should carry it out themselves
B Zoo	A compulsory quarantine isolation observation period for newly arrived animals ＋ faecal parasite examination ＋ serological screening; herd vaccination programmes according to species and local regulations; routine tuberculosis screening in large herbivores and primates (because of the zoonotic risk); frequency of health checks [Verification result: no fixed figure should be given for this item — it varies with species, institutional policy and local regulations, and must be set case by case by the zoo veterinary team]
C Working Animals	Pre-service health and orthopaedic screening (such as screening for hip／elbow dysplasia, to avoid entering service with existing disease); vaccination and deworming adjusted to occupational exposure (for example, water search-and-rescue dogs need enhanced protection against leptospirosis — the same vaccines as in T1 but adjusted for risk); regular fitness-for-duty examinations

9. Zoonoses

Disease	Source of infection	Risk to humans
Rabies	Bites from wild mammals (raccoons, bats, foxes and others, varying by region)	Once symptoms appear it is almost always fatal; anyone bitten must seek medical care immediately for assessment of post-exposure prophylaxis
Avian Influenza	Contact with sick or dead poultry／wild bird droppings	Some viral strains carry a risk of disease in humans; it is a notifiable public health event
Tuberculosis	Close contact between zoo keepers and large mammals (elephants, primates)	Requires institutional biosecurity protection and regular screening
Leptospirosis	Water search-and-rescue dogs coming into contact with contaminated water／the urine of wild rodents	Both humans and animals can be infected; working dogs need vaccination and occupational protection
Psittacosis	Respiratory secretions of birds (zoo／pet birds)	Can cause influenza-like or pneumonic signs in humans
Salmonella	Reptiles (zoo petting areas, pet reptiles)	The risk is higher in children and the immunocompromised; hands must be washed after contact

10. Household toxins and hazards

Sub-field	Hazard	Explanation
A Wildlife	Secondary rodenticide poisoning	Raptors that eat rodents which have taken rodenticide suffer secondary poisoning
A Wildlife	Lead shot／lead fishing tackle	Waterfowl that swallow residual lead shot or lead sinkers develop lead poisoning (see column 7)
A Wildlife	Oil spills／chemical contamination	Marine birds and mammals fouled with oil lose their waterproofing and insulation and need professional cleaning; ordinary people should not attempt to wash them themselves
B Zoo	Disinfectants, toxic plants among enrichment items	Exhibit design must exclude plants and equipment toxic to the particular species
C Working Animals	Chocolate／xylitol and the like (the same as household dog toxins in T1)	Working dogs are equally subject to the general canine toxin list, with the added need to watch for contact with explosives／narcotics training samples in the working environment (occupational exposure for narcotics and explosives detection dogs)
C Working Animals	Heat inside a vehicle	The risk of fatal heatstroke from being left in a vehicle during rest breaks, the same as for ordinary pets

11. Ageing, palliative care and euthanasia decisions

Sub-field	Focus
A Wildlife	For an incurable wild casualty that cannot be released and has poor quality of life, euthanasia is often a professional judgement made by a rescue organisation on welfare grounds, not "leaving it to die"; this judgement must be carried out by a licensed rescue institution／veterinarian, and ordinary people should not decide or carry it out themselves
B Zoo	Aged animals require quality-of-life assessment tools; changes in social dynamics after the loss of a member of the group (in elephant or primate groups, for instance) are also a care consideration
C Working Animals	Retirement procedures must be initiated when the term of service ends or health means the animal is no longer fit for duty; retired animals are commonly adopted by their original trainer／handler; retired working animals showing difficulty adapting behaviourally (similar to role-transition anxiety) need gradual support; the principles of euthanasia decisions are the same as for ordinary pets — no longer making an animal "keep working or keep going" while carrying pain that cannot be relieved

The 5 Deadliest Mistakes People Make (Plain-Language Version, for Readers with No Background)

Finding an injured or apparently abandoned wild animal and taking it home to keep, or feeding it whatever comes to hand. You do not know what it should really eat or how it should be cared for, and feeding the wrong thing is often worse than not feeding at all; the correct approach is to telephone the local licensed wildlife rescue organisation and let professionals handle it.

Seeing a wild animal that is docile and unafraid of people, and reaching out to touch or pick it up. A normal wild animal should be afraid of people and should run. Its not being afraid of you is instead a danger signal — it may be ill (including with infectious diseases that can be transmitted by a bite), or it may be injured and unable to run. Do not approach, do not touch.

Seeing a wild animal that is soaked through or looks weak, and pouring water or milk into it yourself. Forcing anything into the mouth of a weakened animal readily causes it to choke and aspirate into the airway, which is more dangerous than leaving it alone. Wait for professionals to handle it.

Taking children to the zoo and reaching through the railings to feed or touch the animals. This is not only against the rules, it genuinely injures people (bites, scratches) and makes the animals ill (eating the wrong thing). Every zoo's feeding rules are set for the safety of both sides; do not take matters into your own hands.

A working dog or working horse at home still looks able to work, so it is kept at high-intensity work until it breaks down and only then does anyone notice it should have retired. Working dogs and working horses suffer occupational wear just as people do — joints wear out, stamina declines, and they become mentally fatigued. The animal will not say "I cannot do this any more"; it is up to people to notice early that it is walking with a limp, becoming unwilling to work, or slower to respond, all of which are signals to arrange retirement or reduce the workload, rather than waiting until it collapses to act.
