After realizing how helpful it was to have fresh water for the pets handled so easily, I bought another one for an elderly friend. Pets are such important companions to the elderly, but as their owners advance in years it is harder to provide the more frequent level of care needed for the pet. This great source of fresh water is very reliable and I know the pet has water for at least a week. Plan to rinse the bottom tray with soapy water when refilling to keep it sparkling clean. I bought a similar product to dispense dry food and life is better for both the elderly owner and adored pet.
