This debate is often presented as one right answer. In practice both formats can be complete and balanced, and the best choice depends on your cat's health, your routine and what your cat will actually eat.

| Factor | Wet food | Dry food |
|---|---|---|
| Moisture | High — a meaningful water source | Low — cat must drink more |
| Calorie density | Lower per gram | Higher per gram |
| Portion control | Easy, pre-portioned | Easy to over-serve |
| Puzzle feeders | Rarely suitable | Works well |
| Cost per calorie | Generally higher | Generally lower |
| Storage | Refrigerate once opened | Long shelf life |
Cats descend from desert animals and have a weak thirst drive relative to their needs. Getting water through food is one straightforward way to raise total intake, which is why many vets suggest including wet food.
The idea that ordinary dry kibble cleans teeth is overstated; most kibble shatters rather than scrubbing. Specific dental diets are designed differently. Brushing remains the most effective home dental care.
A common practical setup: wet food at meals for hydration and portion control, plus a measured amount of dry food in puzzle feeders for foraging. Keep the total within the daily allowance.
