In order to make sure your cat has enough clean water, you need to replace his water fountain with fresh water at least once every day.

Keeping your cat’s water clean and fresh regularly is essential to prevent the growth of bacteria. Microbes can live in the mouth of your cat which can easily contaminate their water supply and eventually create a place for bacteria to thrive.

If you’re using conventional water bowls, it’s important to have them cleaned and wiped thoroughly using hot water and clean basin every 2 days. Experts recommend that you use glass, porcelain, or stainless-steel bowls since these kinds are easily maintained compared to plastic materials.

Luckily, there’s a water fountain that can give your cat quality water supply throughout the day.
