Both Filou and Tigris are VERY picky with cat food. It is hot here and I feel they eat really nothing. They do that every summer and their weight doesn't change. After some days of eating very badly they usually have one day in which they eat more....

Filou would go for human food but he doesn't get it (of course he gets some bits but only on occasion, never daily, and it could be less than 10 g salmon or just being allowed to lick an avocado peel )

Filou however eats more than Tigris. He is 7,5 lb.
Tigris is extremely picky and he is 13 lb.

I stopped to worry about that. They know what they are doing.
