Very cool that you do that for them. Just one thought is that most rodents are very sensitive to dairy. I know this cause I did a little research on mice and how it really makes no sence for them to like cheese as much as they supposedly do. Also I dont know if you have heard of the raw meat diet for dogs but its really the same concept. I find it funny that many people do this raw meat diet for their dogs and dont realize that their dogs diet is so much healthier than their own.
Yes, I know of the BARF diet. My chiropractor feeds his dog that way to control arthritis. He thinks it's fantastic that I eat this way, but I'm not sure if he does. He hasn't mentioned eating any of these foods. I think his wife is a vegetarian or something, and he has an ongoing argument with her about food.
The pet-store where I got the hamsters, I told the salesman I've been feeding the hamsters raw grass grazed cultured unsalted A2 local butter and raw grass grazed cultured unsalted A2 cheese. He responded to be careful about cheese because he gets constipated by cheese and it will do the same to the hamsters. The hamsters have not gotten constipated yet, but they do get very calm and just different (in good ways) after the dairy. When one of my hamsters eats it, it's more slowly than the other foods, but concentrating on and savoring it and indistractable (single minded).
