Doesn't work perfectly with the chip
You have to wait 3 seconds for it to open. If your pet isn’t in the exact position with the chip, it closes while they’re eating, and since it takes 3 seconds in that exact spot, it’s very hard for them to be able to eat again.
What does work very well is that it doesn’t let another animal eat; there are no gaps. But it’s very difficult to get a pet to adapt to eating here.
