Most cats won't eat everything just because it's there ( there's always the gut bucket exception), they are much better at self regulation than dogs. Kittens need little and often, their stomachs aren't very big. I would just do it by proportion e.g. if it's two pouches a day of wet and 40g a day of dry ( as an example) I would do 2 meals of 0.5 pouches and 2 meals of 10g of dry.
Brilliant thank you. They actually don't always finish everything but I was worried I may be giving them too much, sounds as if I am doing ok.
I have been giving them 1.5 pouches each per day then just leaving dry food down all day (as per the instructions of the rehoming lady) but I was worried I was putting too much dry food down.
They seem happy enough, they love fresh chicken loads, I also gave them fresh salmon, they were fine yesterday but one was a little bit sick today after it. They had their vacs today so maybe it was that. He seems ok now though, they are currently performing a WWE show on the sofa
