1. Cats usually like to drink running water, so owners can buy a pet water fountain for their cats.
2. Mix canned food into cat food. Canned food is rich in moisture, which can provide your cat with enough water.
3. Boil cat grass or catnip in water and give it to your cat to drink. Cats like the taste and will drink more water. 
4. Place water in multiple locations around the house to pique the cat's curiosity and increase its willingness to drink.
5. If the cat really refuses to drink water, you can use a small syringe to force-feed it water in small amounts and frequently.
