Why don't my cats drink out of their water bowl!?

You can try giving them a water fountain. It's a water bowl for cats. Since they love drinking from the faucet, you can try the fountain because the water is moving, just like the faucet. Cats love moving water. You should also give them fresh water every morning, that way they will want to drink from it. Most fountains like that have filters, so it keeps the water fresh. The fountain also has a silent faucet to where the water just beautifully flows back into the water. Trust me, they will drink from that if they can drink from the faucets. They will love it :)
