Hey Ive been reading and I have been seeing alot about What % of protein is ok or needed for rats. Breeding males and females and growing babies. The lab blocks I could get from the local pet shop has 23% protein. I have herd thats way to high. Is it and why is it so bad. Also whats a good % of protein to have. I know lots of people use the Mazuri 6f. I wasnt able to get it in time before the racks were finished. So I picked up this stuff from the local pet shop. I also didnt want to spend 30.00 or so on shipping. Then I find out the local Mazuri dealer cant get the 6f for some reason. Anyways whats the right % of protein and why?
