What this means
Daily water needs scale with body weight: dogs roughly 50–70 ml per kg, cats 40–60 ml per kg. A 20 kg dog needs about 1–1.4 litres a day. Food matters too — wet food can supply most of a cat's intake, while dry food contributes little. Tracking the cups you see them drink gives a rough picture of whether they're hitting their range.
Recommendations
- Cats naturally drink little — a fountain and multiple bowls placed away from food encourage intake.
- In hot weather or after exercise, offer extra and keep the range topped up.
- If your pet's drinking jumps suddenly up or down, that's worth a vet check — it can signal illness.
Watch out
- Intake needs rise with heat, activity and illness — the range is a healthy baseline, not a ceiling.
- Sudden changes in thirst are a medical flag, especially in older pets and cats.
