The most expensive cat health problems are almost always the preventable ones. Not the rare genetic conditions or the freak accidents. The slow ones: dental disease left for four years, a kidney that quietly lost function while nobody ran bloodwork, a cat carrying two extra kilos since it was three.
This page is the map. Each section gives you the short answer and points to the article that covers it properly. Written from how Pau and Sun manage health at Bangkok Cats, a world championship cattery, and from Pau's background in animal biology and biosecurity.
Nutrition comes first, and it is not close
Every other section on this page depends on this one. A cat eating badly has weaker immunity, worse teeth, less muscle in old age and a shorter life. No supplement or treatment buys that back.
Two things matter most beyond adequate protein. Taurine, which cats cannot make and which the heart and retina fail without. And moisture, because a cat on dry food alone lives mildly dehydrated for years, and the kidney pays for it.

Vaccination and parasites in Thailand
Four core vaccines cover the serious infectious threats here: panleukopenia, herpesvirus, calicivirus and rabies. Panleukopenia is the one not to gamble on. It survives in the environment for months and kills a high proportion of unvaccinated kittens.
Parasites are a year-round problem in this climate rather than a seasonal one, and indoor cats are not exempt. Fleas arrive on clothing and through window gaps.
Dental disease, the one nobody watches
Most cats have some periodontal disease by three. That is not inevitable, it is what happens without prevention. And it does not stay in the mouth: bacteria from inflamed gums reach the kidneys, heart and liver over years.
Chewing is the most effective daily intervention. Raw meaty bone does mechanical cleaning that no dental treat replicates.
Weight
A chubby cat reads as a well-loved cat in Thailand and in most places. It is closer to the opposite. Obesity raises the risk of diabetes, joint disease, liver disease and urinary problems, and it shortens life measurably.
Judge by body condition, not by a number. Ribs findable without pressing hard, a visible waist from above, a belly that does not hang. Breed changes the ideal shape, which is why a single standard misleads.
The urinary tract, and why it is an emergency
Urinary disease is common in cats and one presentation of it kills fast. A male cat straining in the tray with nothing coming out may have a blocked urethra, and that is fatal within a day or two without treatment. It is the single most time-critical thing on this page.
Urine colour and litter habits are the earliest signal most owners get.

Neutering
Neutering changes metabolic rate, which means the same portion that maintained a cat before surgery will put weight on afterward. Timing, recovery and the portion adjustment are all worth getting right rather than guessing.
Stress, the risk that does not show on a blood test
Chronic stress suppresses immunity, drives urinary disease, and shortens life. A great many problems that arrive at a vet with a physical label have a stress component underneath that nobody addresses.
The common causes indoors are too little territory and vertical space, unpredictable routine, an animal in the house the cat never bonded with, and nothing to do. Condominium living in Bangkok concentrates all four.
The signs are over-grooming to bald patches, soiling outside the tray, unprovoked aggression, persistent hiding, and appetite change. Fix the environment before medicating the symptom.

The senior cat, from eight onward
Cats are senior from around eight and geriatric from around twelve. Two things change that owners usually get wrong.
Kidney function declines quietly. Annual bloodwork from seven catches it while diet and management still change the outcome. Waiting for visible illness means the window has closed.
And muscle mass falls even in cats eating normally. That is sarcopenia, and low protein accelerates it. The old advice to cut protein in senior cats is wrong as a general rule. Protein restriction belongs to advanced kidney disease specifically, guided by bloodwork, not to age.
What cannot wait
Some signs are not a wait-and-see. Straining to urinate with little or nothing produced. Laboured or open-mouthed breathing, which a cat does not do unless it is in real trouble. Sudden hind limb paralysis. Collapse, seizures, blood in vomit or stool, or a full day without eating or drinking.
Any of these means the vet now, not tomorrow.

Common questions
How often should a healthy cat see a vet?
Once a year up to about seven, twice a year after that. The second visit is not padding. It halves the time a developing problem can run unnoticed.
Do indoor cats need vaccines and parasite prevention?
Yes to both. Panleukopenia survives on shoes and clothing, and fleas come in through window gaps. Indoor lowers exposure. It does not remove it.
My cat seems fine. Is bloodwork at seven really necessary?
That is the point of it. Kidney and thyroid changes are well advanced before a cat looks unwell. Testing a healthy cat is what gives you a baseline to compare against later.
Should I reduce protein for my older cat?
Not as a rule. Senior cats lose muscle, and low protein makes that faster. Restriction is for diagnosed advanced kidney disease, decided by bloodwork with your vet.
What is the one thing that matters most?
The food. It sits underneath dental health, weight, kidney function and immunity all at once, and it is the only item on this page you control at every single meal.
Where to start
If your cat is under three, start with nutrition and get the vaccination schedule right. If it is between three and seven, dental and weight are where the damage accumulates. If it is over seven, book the bloodwork.
