True, but might I suggest a thorough search for dried cat food ? It may not be readily available but might be available in a speciality store, perhaps further away than is optimum.
Are there no ex-pat British or American cat lovers in the vicinity ? if there are, they may know where to buy dry cat food, or might be able to spare you some.

If all else fails, I see two options, one would be dried food intended for human consumption something like dried beef.

Or try canned wet cat food that has been frozen. Serve one portion fresh from the can, and another larger portion that is frozen, this will defrost fairly quickly, but might remain frozen for 6 hours, cold for another 6 hours and edible for 12 hours after that. Not really long enough, but better than nothing.
