Microchip pet feeder (BH8 Bournemouth)

Hi
I know it’s a big ask, but I wonder if anyone has a sureflap microchip cat bowl / feeder (or any make) that works with the microchip in my cat!
She has to have expensive gluten free food, or she gets very ill.
However I have many cats. They all want her expensive food.
Looking for a way to stop them eating her food, and / or her stop eating their food.

Thank you so much if you have anything suitable that you’re happy to offer.

Sam (and Cuddles the cat 🐾)
