Mmmm.. I will use soya milk on hamsters 9not on them i meant on food!!) to see if they like it..
My children.. we dont "boiled" the cow milk, but however, they can eat in small amount - cheese sauce.. only tablespoon.. because it bee "heat treated".. the lactose is Milk sugar - hospital describe to me.. imagine COW milk lactose is 50p size.. when use in cooking.. it turn into 20p size..
lot of milk intolerance people can eat goat milk in small amount because lactose is 20p size. (Milk allergic cannot eat goat milk) does that help understand??
