Making cat food at home?

Good morning/afternoon evening, cat parents!

I wonder if I am able to cook something at home that will be nutritional enough for cats?

Currently, there is a cat food crisis in my country, no cat food available in any of the stores, and the brands I find that are scarce and are just ridiculously expensive (i have 9 cats).

I'm not absolutely sure how this will work out, the cooking, and if they can get used to it, because it doesn't look like the problem at the moment will resolve anytime soon.
