Hi Jackspratt,
If you want to drop me a PM, happy to answer any and all of your questions. Feeding requirements are not too different to moggies but I do supplement my lot with some raw and cooked meats. The boys in particular have big appetites but also have delicate tummys (bengal breed characteristic).
I would say the biggest difference you need to be aware of is personality. They can be fairly demanding and you need to be prepared for that. Happy to chat you through.
