🐱 Body weight

🐱 How Much Water Does a Cat Need Every Day?
A healthy cat generally needs:
40–60 ml of water per kilogram of body weight per day.
For example:
| Cat Weight | Recommended Daily Water Intake |
|---|---|
| 3 kg (6.6 lbs) | 120–180 ml |
| 4 kg (8.8 lbs) | 160–240 ml |
| 5 kg (11 lbs) | 200–300 ml |
| 6 kg (13.2 lbs) | 240–360 ml |
This includes water from:
💧 Drinking water
🍖 Wet food moisture
🥣 Other food sources
🍖 Does Diet Affect How Much Water a Cat Needs?
Yes.
A cat’s diet has a major impact on hydration requirements.
🥩 Cats Eating Dry Food
Dry food usually contains around 10% moisture.
Cats eating mainly dry food need to drink more water to maintain proper hydration.
🍲 Cats Eating Wet Food
Wet food can contain a much higher percentage of water.
Cats eating wet food may naturally drink less because they already receive moisture from their meals.
📊 Dry Food vs Wet Food Hydration Comparison
| Food Type | Water Content | Additional Drinking Need |
|---|---|---|
| Dry Food | Low moisture | Higher |
| Wet Food | High moisture | Lower |
| Mixed Diet | Medium | Moderate |
