The most expensive cat health problems we see are almost always preventable. After more than eleven years of breeding champion cats at Bangkok Cats and studying animal biology and biosecurity, the pattern is consistent: the cats that stay healthiest longest are the ones whose owners understood the basics early and applied them consistently. This guide covers those basics in full.
Nutrition is the foundation of everything
Every other section of this guide depends on this one. A cat eating a poor diet will have compromised immunity, a higher disease burden, worse dental health, lower muscle mass in old age and a shorter lifespan. No amount of supplements, treatments or vet visits fully compensates for years of inadequate nutrition.
Cats are obligate carnivores. Their entire physiology is built around digesting animal protein. The two most critical dietary requirements beyond sufficient protein are taurine and adequate moisture. Taurine deficiency causes heart disease and blindness. Chronic dehydration, which is extremely common in cats fed exclusively on dry food, contributes significantly to kidney disease, one of the leading causes of death in older cats.
We feed our Bangkok Cats champions raw food. We stock only products we would give our own cats. If you are considering improving your cat's nutrition, start with our raw feeding guide on this blog.
Vaccinations in Thailand: what your cat actually needs
Thailand has specific disease pressures that differ from Western countries. The core vaccines every cat in Thailand needs are protection against feline panleukopenia (also called feline distemper or parvovirus), feline herpesvirus, feline calicivirus and rabies. These four cover the most serious and most common infectious threats.
Feline panleukopenia is particularly prevalent among unvaccinated cats in Thailand and has a fatality rate that can reach ninety percent in young kittens without treatment. It spreads easily and survives in the environment for long periods. This is not a vaccine you skip.
FIP (Feline Infectious Peritonitis) caused by feline coronavirus is also notably common in Thailand. Most cats carry the underlying coronavirus harmlessly, but in some individuals it mutates into FIP. There is now a treatment available (GS-441524) that has transformed outcomes for FIP-positive cats, but prevention through good husbandry and avoiding high-stress environments remains the first line of defence.
For indoor-only cats, your vet will advise on whether additional vaccines beyond the core set are necessary based on your specific circumstances. The general principle is: do not skip core vaccines, and discuss non-core vaccines with your vet rather than deciding based on internet advice.
Dental health: the most neglected area of cat care
By the age of three, most cats have some degree of periodontal disease. By four, the majority have visible dental problems. This is not inevitable. It is the result of diet and the absence of preventive care.
Dental disease in cats is not just about bad breath or discomfort. Bacteria from infected gums enter the bloodstream and over time cause damage to the kidneys, heart and liver. The cat that seems fine at eight years old but has had untreated dental disease for years is quietly accumulating systemic damage.
The most effective dietary contribution to dental health is chewing. Raw meaty bones provide mechanical cleaning that no dental treat or chew toy can replicate. This is one of the practical reasons a raw or partly raw diet is beneficial beyond just nutritional content.
For brushing, the earlier you introduce it the better. Cats that are accustomed to having their mouths handled from kittenhood accept tooth brushing far more readily than adult cats introduced to it suddenly. Use a pet-specific toothpaste as human toothpaste contains xylitol which is toxic to cats.
Annual dental checks with your vet allow problems to be caught early. Professional dental cleaning under anaesthesia is sometimes necessary and significantly better than allowing disease to progress untreated.
Weight management: why fat cats are not healthy cats
There is a persistent cultural tendency in Thailand and elsewhere to associate a chubby cat with a well-cared-for cat. The opposite is closer to the truth. Obesity in cats significantly increases the risk of diabetes, joint problems, liver disease, urinary tract disease and a shortened lifespan.
Every breed has a different ideal body shape, which is why breed-specific knowledge matters. A British Shorthair is naturally stockier than a Siamese. Judging weight by a single standard misses this variation. The most reliable assessment is the body condition score: you should be able to feel your cat's ribs without pressing hard, there should be a visible waist when viewed from above, and the belly should not hang noticeably.
The primary driver of feline obesity is caloric excess combined with insufficient activity. Free-feeding dry food is the most common cause. Dry food is calorie-dense, low in moisture and highly palatable in a way that makes it easy for cats to overconsume. Switching to measured meals, increasing protein and decreasing carbohydrate content, and introducing regular play all contribute to weight normalisation.
We covered this topic in detail in our blog post on why fat cats are not cute. The health implications are serious and worth understanding fully.
Stress: the invisible health risk
Stress in cats is widely underestimated as a health factor. Chronic stress suppresses immunity, contributes to urinary tract problems, causes or worsens behavioural issues and shortens lifespan. Many of the health problems Thai cat owners bring to vets have a stress component that goes unaddressed.
Common stressors for indoor cats include insufficient territory and vertical space, unpredictable routines, the presence of other animals they have not bonded with, loud noise and lack of mental stimulation. In Thailand specifically, condominium living presents particular challenges because space is limited and environmental enrichment is often minimal.
Signs that a cat is under chronic stress include over-grooming to the point of bald patches, house soiling outside the litter box, aggression that seems unprovoked, hiding persistently and changes in eating habits. If you notice these signs, addressing the environment comes before medicating the symptom.
Parasites in Thailand: what to watch for
Thailand's tropical climate creates year-round parasite pressure that does not exist in colder countries. Fleas, ticks, ear mites and intestinal worms are all common even in indoor cats. The reason indoor cats are not immune is that fleas can enter on clothing, other animals or through gaps in doors and windows.
Year-round parasite prevention is advisable in Thailand rather than the seasonal approach used in temperate climates. Your vet can recommend appropriate preventive treatments based on your cat's lifestyle and exposure risk.
Intestinal parasite checks via annual fecal tests are worth doing, particularly for cats that have access to outdoor areas or that eat raw food from sources you have not thoroughly verified.
The senior cat: what changes at eight and beyond
Cats are considered senior from around eight years old and geriatric from around twelve. The health management of older cats differs from younger cats in several important ways.
Kidney function naturally declines with age. Regular bloodwork from age seven or eight onwards allows early detection of kidney disease, when dietary and medical management can significantly slow progression and maintain quality of life. Waiting until a cat is visibly unwell before testing means the opportunity for early intervention has already passed.
Muscle mass decreases in older cats even when they appear to be eating normally. This is called sarcopenia and it is accelerated by low-protein diets. Maintaining adequate dietary protein in senior cats is important and directly contradicts the outdated advice to reduce protein in older cats as a general rule. Protein reduction is only appropriate for cats with advanced kidney disease and should be guided by bloodwork, not assumed.
Senior cats also benefit from more frequent vet checks, at least twice yearly, softer food if dental problems make eating difficult, environmental modifications like lower-sided litter boxes and ramps to elevated resting spots, and increased warmth as thermoregulation becomes less efficient.
When to call the vet: signs that cannot wait
Some signs in cats indicate an emergency and should never be managed with a wait-and-see approach. These include straining to urinate with little or no output, which can indicate a urethral blockage that is fatal within twenty-four to forty-eight hours. It also includes laboured or open-mouth breathing, which cats do not do unless they are in serious respiratory distress. Sudden hind limb paralysis is another emergency and is often caused by aortic thromboembolism. Collapse, seizures, severe vomiting or diarrhoea with blood, and inability to eat or drink for more than twenty-four hours all warrant immediate veterinary attention.
For non-emergency changes worth monitoring, signs of illness we covered in detail in a separate post on this blog include changes in appetite, personality shifts, changes in stool consistency and unusual weight loss or gain.
Building a health routine
A practical annual health routine for a cat in Thailand looks like this. A full veterinary check twice a year from age seven and once a year for younger adults. Core vaccinations updated on the schedule your vet recommends. Year-round parasite prevention appropriate to your cat's lifestyle. Monthly weight checks at home, either with a kitchen scale for smaller cats or by weighing yourself holding the cat and subtracting your own weight. Regular dental observation and professional cleaning as your vet advises. Bloodwork annually from age seven to catch kidney, liver and thyroid changes early.
None of this is complicated. All of it is significantly cheaper than treating the conditions that develop when it is skipped.
