This is an official pet water bowl that heats water to 30-35 degrees Celsius (feels a bit cooler in reality). The water pressure can be adjusted within the pump (adjusting it is tricky, so splash protection is a must until you get used to it). No filters required. Comes with a spare pump. AC power supply. 14 cm in diameter. Calm colors: light beige and green. It has been used, so there is some dirt. Please be aware of this. ● Other notes: I have a cat. ■ Please follow the official rules for purchase. There are no personal rules such as prior greetings. ■ To avoid trouble, I do not accept any negotiations, including price reductions. There seem to be many other similar items for sale, so if you are not satisfied, please look elsewhere. ■ Shipping will be on the next weekday if purchased on or after Friday, so please be aware that it will take some time for you to receive it.
