Quick answers to common questions from cat parents

A cat needs approximately 50-60ml of water per kg of body weight per day. For a 4kg cat, that's about 200-240ml (roughly 1 cup). Cats on dry food need more, while wet food provides significant hydration.

Cats have a low thirst drive evolved from desert ancestors. They may prefer running water (fountains), dislike the bowl's location (too close to food/litter), or find the water stale. Try a ceramic fountain placed away from their food.

Wet food (70-80% moisture) provides significant hydration. A cat eating only wet food may get 60-80% of their water needs from food alone. However, always provide fresh water โ€” especially if feeding dry food as the primary diet.

Common signs: lethargy, dry/tacky gums, sunken eyes, loss of appetite, and decreased skin elasticity (the 'skin tent' test โ€” gently pinch the skin between their shoulders; if it doesn't snap back quickly, they may be dehydrated).

Yes! Many cats instinctively prefer moving water โ€” it's fresher and more interesting in their eyes. Cat water fountains can increase water intake by 50% or more. The constant filtration also keeps water cleaner and more appealing.
