I've been researching a lot when it comes to hamster food, and I've found a good mixture of food that I want to feed my hamster. But I want to give some more fibre from time to time, just to make sure that he gets enough, as the fibre content is a bit below the recommended amount.
I've read that they can have lentils, but do they have to be cooked, or can I give them uncooked?
Is there anything else I can give to give some extra fibre
?
