Water is an essential part of a cat's diet
– an average pet cat requires between
150ml and 200ml of water everyday.

Cats can become dehydrated.
How to determine dehydration: A cat may be dehydrated even when drinking plenty of water due to medical problems, over-activity, heat or stress. One way to easily determine this condition is to check for skin elasticity. On the upper back just below the shoulders, using your thumb and forefinger, pinch the skin gently, lift up and then let go. If the skin returns to normal quickly, your pet is absorbing enough water. If not, encourage your cat to drink more water and call the vet immediately.
