Dear customer,
Thank you for sharing your feedback regarding your recent purchase of the fountain.
We appreciate your positive comments about the fountain's cuteness and quiet operation. In general, based on the water intake of cats, 1.5 liters is sufficient. If you have multiple cats, we recommend purchasing a larger capacity fountain. For example, we have a smart fountain with a 2-liter capacity available for sale: https://happyandpolly.com/collections/drinking-fountain/products/automatic-cat-water-fountain-upgraded-filtration-system?variant=41696600522845.
Additionally, we apologize for the difficulty you've experienced in cleaning and removing white stains from the outside of the fountain. Could you please contact our customer service email and provide a photo of the white stains? This will help us identify what the stain is and assist you further.
We are committed to providing you with the best possible experience and look forward to resolving these issues for you.
Best Regards,
Rose
