Using these ceramic pet bowls is super easy. Just fill them with your pet's food or water and place them where your pet can reach. When it's time to clean, you can simply put them in the dishwasher. They're also microwave - safe, so if you need to warm up your pet's food, go ahead. As for maintenance, avoid dropping the bowls on hard surfaces as they're ceramic and can break. Regularly check for any cracks or chips. If you notice any damage, it's best to replace the bowl to keep your pet safe.
