Most cat food decisions get made backwards. You pick a bag, then look for reasons it was the right bag. This page starts from the other end: what a cat is, what that means for what goes in the bowl, and where to read more on each piece.
Everything below is drawn from how Pau and Sun feed at Bangkok Cats, a world championship cattery where every cat has eaten a raw diet its entire life. Each section is a short answer with a link to the article that covers it properly.
Start with what a cat actually is
Cats are obligate carnivores. Not by preference, by classification. The teeth have no grinding molars, the saliva has no amylase, the stomach runs at a pH of 1 to 2, and the gut is roughly four times body length against twenty for a cow. Every part of that anatomy assumes the incoming meal is raw animal tissue.
The clearest single piece of evidence is taurine. Cats cannot synthesise it in useful quantities and lose it continuously through bile. Without a daily dietary supply the heart muscle weakens and the retina degrades. There is no plant-based substitute.

What actually goes in the bowl
A complete raw diet is a ratio, not an ingredient. Roughly eighty percent muscle meat, ten percent edible bone, ten percent organ, with at least half the organ portion being liver. Muscle meat alone is not a diet. Liver alone is not a diet. The proportions are the diet.
Organ is where most raw diets fail. Too much liver too fast produces loose stools, the owner blames raw food, and the cat goes back on kibble. Introduce heart first, then liver slowly, then kidney.

Is raw food safe
The bacterial objection deserves a direct answer rather than reassurance. A cat's stomach acidity and fast transit time are specifically adapted to raw animal protein carrying a bacterial load. Sourcing and handling are where real risk lives, not in the practice of raw feeding itself.
Commercial raw food is a different question again, because it involves a kill step. Which kill step a manufacturer uses changes what survives in the food and what it does to the nutrients.

How to switch a cat over
Most people who give up on raw quit around day four, which is usually the middle of the adjustment rather than evidence that it failed. A cat that has eaten dry food for years has a gut microbiome adapted to carbohydrate. Changing that takes weeks, and the stools during those weeks are not a verdict.
Go gradually, watch the stool, and hold at the last ratio that worked rather than pushing through.

Feeding kittens
A kitten raised on raw from weaning never needs a transition at all. Its digestive system was never adapted to anything else. The requirements differ from an adult in quantity rather than kind: more food relative to body weight, more meals per day, and closer attention to the calcium and phosphorus balance that bone provides.
Raw, freeze-dried or wet
These formats are not interchangeable. They differ in moisture, in how they are preserved, and in what the preservation does to heat-sensitive nutrients. Knowing which compromise you are making is more useful than picking on convenience alone.
Common questions
Is raw feeding expensive?
More per meal than entry-level kibble, less than the veterinary bills associated with the conditions that high-carbohydrate diets contribute to. Which number is bigger depends on how far ahead you count.
Can I feed raw in Thailand's heat?
Yes, with ordinary food hygiene. Keep it frozen, thaw in the fridge rather than on the counter, serve straight from cold and lift anything uneaten after thirty minutes.
Does a raw diet need supplements?
A correctly balanced one does not. Taurine comes from heart, calcium from edible bone, vitamin A from liver. The exception worth considering is a little fish oil if your protein rotation has no oily fish in it.
My cat refuses raw food. What now?
Usually a texture and temperature problem rather than a taste one. Serve at room temperature rather than fridge cold, and try lightly searing the outside while leaving the middle raw.
Can senior cats switch?
Yes. The nutritional case does not change with age. The exception is diagnosed kidney disease, where protein and phosphorus need managing with your vet.
Where to start
If your cat is already eating raw, the ratios article is the one that will improve the diet most. If you are still deciding, start with the digestive system. If you have decided and want to begin, the 21 day plan is the practical route.
