How much food do you give your cats?

Bertie has dry food down 24hrs a day. 4-5 Dreamies at 3pm and a Felix pouch at 5 pm.
He can tell the time

Mine eats two pouches of Felix at night and about a decilitre of dry food over the course of 24 hours.

He' s big and out and about a lot, but I feel two pouches of Felix is perhaps a bit much, as when his brother was alive, they shared two pouches. I've spoilt him since Storm died, I know.

Sometimes he adds a mouse or two to his daily diet.

I ignore the I'm hungry look that all cats can put on on demand.

Looking at the advice from (I think) Cats Protection, and talking to friends, we are giving our cat 2 pouches a day, with dry food available too, though she's not very interested in this. I don't see her becoming fat as she's not that interested in food (though that has its own drawback in terms of teaching her to use the cat flap!)

My cats expect to eat every time I go in the kitchen. One has a digestion problem and has mainly wheat-free food. Generally we feed them 4 times a day (between approx 50 and 100g), with some biscuits in between and at bedtime. They're both 'well-covered'. The younger one often turns her nose up at the food and goes and catches herself a rabbit. So no way can we regulate how much she eats!
