How much should I be feeding?

I've just bought a bag of Autarky for Roger, and I find the feeding guidelines a bit confusing, so I was hoping someone will be able to help.

He is currently on 250g of Harringtons per day and two weeks ago was 6.45kg, so he's somewhere in that region now. He's four months old now.

I'm thinking of just going for 250g again and seeing how he does. Any thoughts?

Hiya Eris, just go on what the recommended guidelines are on the new food and use them as that. Up it if you think or feed less if you think. I have just changed and she now has less as there is more nutrients hope that made sense lol) Xx

I'd always go by the guidelines on the bag because all the different brands have different nutritional values.

If they're complicated then by all means carry on with the same amount & just watch his weight to see if it needs to be increased/decreased.
