@Wilson I'd guess there's possibly some similarities with what's available for you and what's available for me (US, Minnesota)
If you've got Solid Gold branded foods, give them a shot, they're a lot like cat crack and good for picky eaters. If you can get Weruva, specifically the "Cats in the Kitchen" line, there's one that's chicken that, if your kitty likes the plain chicken breast, s/he would probably love. It's basically shredded chicken that looks and smells tastier than any human canned chicken I've tried.
With any food, try Forti-Flora or Advita probiotics sprinkled on top, too. They have flavor and smell enhancers added to them (animal digest) to make them more appealing to sick and picky eaters
I've had a few picky eaters in my time, and it can be stressful to try to find what they'll eat (one of mine insists on a new flavor every day, another one will only eat one flavor and only if the texture is "perfect" for her)
