This is a feeder that can be used when you want to separate food for multiple pets. By registering the microchip (or included tag) of the dog or cat you want to feed in advance, the lid will automatically open when the registered pet approaches. Requires 4 D batteries to operate. Batteries are not included, so please prepare them. The instruction manual is in English (other languages are also available, please check the photos of the manual), but it can be used intuitively with illustrations. Two food bowls are included. One is unused (the one with the divider). The other one (without the divider) has been used and cleaned with bleach, but the black marks as shown in the photo remain, so please be aware of this when purchasing. Overall, there is some wear and tear, so please refrain from purchasing if you are concerned. We have included as many photos as possible, but if you have any concerns, please contact us and we will take additional photos. The original price was about 45,000 yen and was purchased on Rakuten. I used it to separate food for one cat in a multi-cat household, but I no longer need it, so I am selling it.
