The domestic cat naturally drinks little water: it is a desert animal and does not feel thirst like we do. However, at home, with dry food and a controlled climate, chronic low hydration leads directly to kidney and urinary problems. Here are 8 practical strategies.
1. Prevalent wet food
The first trick is not to "make them drink": it is **to increase the water in food**. A wet diet (75-80% water) doubles the water intake compared to dry alone.
2. More water bowls in more rooms
Cats prefer **not to drink where they eat** (an evolutionary legacy to avoid contaminating water with their prey). Place 2-3 bowls in different areas of the house, away from the food bowls.
3. Running water fountains
Running water attracts cats: it simulates a natural stream. Most cats drink more with a fountain. Cost: €30-60.
4. Fresh water, changed every day
Stagnant water loses flavor and attracts dust. Change it at least once a day. Wash the bowls weekly.
5. Ceramic or glass bowls
Plastic ones release a "chemical" taste and harbor bacteria. Ceramic or glass are better.
6. Add broth (no salt, no onion)
Diluted chicken or fish broth (1:5) to the water or food. Increases palatability.
7. Ice in the bowl in summer
Many cats love fresh water. An ice cube in summer is a little enjoyable play.
8. Water in "high" places
Some cats prefer to drink in elevated spots or near the tap. A bowl on the kitchen sink may be appreciated more than one in the corner.
How much water should they drink
An adult cat weighing 4 kg should consume **160-200 ml of water per day** (total, considering wet + bowl). If drinking only from the bowl: 60-100 ml visible.
If they seem to be drinking suspiciously much (over 100 ml/kg per day only from the bowl), talk to your veterinarian: it may be a sign of **diabetes, hyperthyroidism, kidney failure**.
The state of affairs
Hydration is the single most important lever for the health of a cat's kidneys. A few adjustments, consistently applied, can reduce the risk of urinary and kidney problems by 50-70%.
