Cats are the second-most popular companion animal in the world and the most frequent free-roaming companion animal across the countries WARN is preparing to work in. Whether you live with a single indoor cat, run a small cat charity, or quietly feed a colony of community cats outside your home, the principles of good cat care are the same — they just scale up. This guide covers everything responsible cat carers should know, and goes further than most published care sheets on three under-covered topics: outdoor shelter design, TNVR for community cats, and recognising serious illness early.
Daily care: food, water and routine
Cats are obligate carnivores. Their bodies require nutrients — taurine, arginine, arachidonic acid, vitamin A in active form — that can only be obtained from animal protein. Get the food right and almost everything else gets easier.
- Wet food first. At least 60-70% of daily food intake should be wet food. Cats evolved to get most of their water from prey and frequently fail to drink enough on a dry-only diet. Chronic low-level dehydration is one of the main drivers of feline kidney disease.
- Twice-daily meals, not constant grazing. Free-feeding contributes to feline obesity, which the World Small Animal Veterinary Association (WSAVA) identifies as one of the most common preventable health problems in cats.
- Life-stage matters. Kittens need kitten-specific food until 12 months. Senior cats (10+) often need diets adjusted for kidney function and protein quality.
- Fresh water, always. Replace water at least once a day. Place water bowls away from food — cats have an instinctive aversion to water near prey.
- Never give cow's milk. Most adult cats are lactose intolerant.
Indoor enrichment: how to stop a bored cat becoming a difficult cat
Most behaviour problems in indoor cats — overgrooming, aggression, inappropriate toileting, destructive scratching — trace back to one cause: under-stimulation. A cat in an apartment needs deliberate enrichment:
- Vertical space. Cat trees, shelves, window perches. Cats feel safest above the room, not in it.
- Hunting play, twice a day. Ten to fifteen minutes with a wand toy mimicking prey movement — slow stalk, fast chase, brief "catch", reward with a small wet-food snack. This single change reduces inter-cat aggression and destructive behaviour more than any other intervention.
- Scratching surfaces. Vertical sisal posts and horizontal cardboard. Cats scratch to mark, stretch and condition their claws; refusing them surfaces guarantees they choose your sofa.
- Hiding places. A simple cardboard box is one of the most effective stress-reducing items in a cat's environment.
- Litter trays. One per cat plus one extra, placed in quiet locations, scooped daily, fully cleaned weekly. Most "litter box problems" are environment problems.
Veterinary care: the non-negotiables
Regardless of where in the world a cat lives, the veterinary baseline is the same:
- Annual health check. Weight, dental, kidney bloods from age 7, blood-pressure check from age 10.
- Core vaccinations. Feline panleukopenia (FPV), feline herpesvirus (FHV-1), feline calicivirus (FCV). Rabies vaccination is essential in rabies-endemic countries and is recommended by WHO and WOAH wherever cats may come into contact with potential vectors.
- Neutering by six months. Reduces mammary cancer, eliminates pyometra, reduces fighting, eliminates accidental litters. There is no health benefit to allowing a "first litter".
- Microchipping. A microchip is the single most effective intervention against permanent loss.
- Parasite prevention. Monthly flea-and-tick treatment, quarterly worming. Both are cheap and prevent serious illness.
- Dental care. Roughly 70% of cats over the age of three show signs of dental disease. Annual dental checks should be standard from age three onwards.
Community cats: the welfare population most people miss
Community cats — sometimes called feral cats, street cats or stray cats — are the cats that live outdoors near people but are not anyone's pet. They are usually born to other community cats, deeply bonded to their territory, and often unsuited to indoor adoption. Good cat charity work treats them as a recognisable population in their own right, not as "strays to be removed".
TNVR — trap, neuter, vaccinate, return
The internationally recognised approach to community cat populations is TNVR. The cat is humanely trapped, brought to a clinic, neutered, vaccinated (rabies plus core feline vaccines), ear-tipped (a tiny notch on the left ear, the universal sign of a sterilised colony cat), and returned to exactly the location it was trapped from. Done at sufficient scale (≈70% sterilisation coverage), TNVR stabilises and then reduces the colony, dramatically lowers fighting and disease transmission, and is the strategy recommended by major animal welfare bodies for free-roaming cats worldwide.
Outdoor shelters that actually work
If you care for community cats, especially in colder months, shelter is critical and is the single area where most amateur cat-care advice goes wrong. A good outdoor cat shelter:
- Is elevated off the ground by at least 10 cm to stay dry.
- Has two exits so a cat is never cornered by a predator or another cat.
- Uses straw, never blankets or towels. Straw insulates and stays dry; blankets retain moisture and freeze.
- Has a small entrance (about 15 cm diameter) — large enough for the cat, small enough to keep heat in and bigger predators out.
- Is placed against a wall in a quiet area, away from foot traffic.
- Is paired with a protected feeding station at least a metre away — never inside the shelter.
Feeding stations
Feed at set times, in set quantities, in protected containers. Avoid leaving food out overnight (it attracts wildlife and pests). A reliable feeding routine is also what makes humane trapping possible when it is time for TNVR.
Recognising serious illness — the early signs people miss
Cats are extraordinary at hiding illness. The following are the early warning signs every cat carer should know:
- Sudden change in water consumption. Either much more or much less. Often the first sign of kidney disease, diabetes or hyperthyroidism.
- Weight loss despite normal appetite. Strongly suggestive of hyperthyroidism or diabetes in older cats.
- Reduced grooming. A coat that becomes greasy, matted or unkempt is often the earliest sign of pain — particularly dental pain or arthritis.
- Hiding more than usual. One of the most reliable behavioural signs that a cat is unwell.
- Difficulty urinating. Straining, frequent trips to the litter tray, vocalising. In male cats especially, this is a veterinary emergency — urinary blockage can be fatal within 24-48 hours.
- Breathing through the mouth. Cats almost never pant. Open-mouth breathing in a cat at rest is an emergency.
First aid basics
Every cat carer should know the absolute minimum first aid:
- Bleeding: direct pressure with clean cloth, get to vet.
- Suspected poisoning: never induce vomiting in a cat — go straight to vet. Bring the packaging.
- Heatstroke: cool gradually with damp towels, fan, get to vet.
- Choking: only attempt to remove visible obstructions. Otherwise straight to vet.
- Seizure: do not restrain. Time the seizure, keep away from edges and stairs, vet immediately if longer than 2 minutes or if first ever.
Do not give human medication. Paracetamol is fatal to cats. Ibuprofen is fatal to cats. Lily plants — including pollen on a cat's coat — are fatal. Antifreeze (ethylene glycol) is fatal in tiny quantities.
How a cat charity supports cats globally
A serious cat charity in 2026 does three things well: it funds direct veterinary care, it builds capacity for community cats through TNVR, and it supports responsible in-country adoption. What it does not do is treat community cats as a nuisance to be removed or rely on long-distance international relocation as its primary intervention. Long-distance relocation helps one animal at a time; TNVR and partner-funded cat shelter capacity help thousands.
When choosing a cat charity to support, look for:
- Registered charity status with up-to-date accounts.
- A clear veterinary policy and a published TNVR or community cat strategy.
- Honest reporting on outcomes, not just intake.
- A focus on the populations of cats who are most under-served — community cats, cats in countries with little or no cat-shelter infrastructure, cats in the meat trade.
How WARN fits in
World Animal Rescue Network is a UK cat charity in its launch stage. We do not run UK cat adoptions — if you searched for a local cat charity to adopt from, please support a UK rescue or shelter. Where we focus is the cats almost no one else funds: community cats in Vietnam, Indonesia, Pakistan, Kenya and Tanzania, the cats caught up in the Southeast Asian meat trade, and the broader population of free-roaming cats living in cities with little to no veterinary cover.
When a cat dies
Every cat care journey ends the same way, and it is one of the hardest parts of loving a cat. If you have recently lost a cat, our pet loss support guide covers cremation, talking to children, and recognising grief, and our in memory giving page explains how a tribute for a cat helps community cats overseas.
Help the cats WARN is being built for
WARN's Global Cat Protection Appeal will fund partner cat rescue and cat shelter capacity across Vietnam, Indonesia, Pakistan, Kenya and beyond — humane catch-neuter-vaccinate-return work, veterinary care for injured community cats, and responsible in-country cat adoption for rescue cats who can be safely rehomed.
Read the Global Cat Protection Appeal for the full plan, or donate today to fund our first surgeries, vaccinations and cat shelter weeks. Every pound helps another rescue cat get a fair start.
