i just switched from db to 6f for my breeders and kent 23% for my growups only 12 bucks for the kent and all in all the smell is less waste is way less and bigger litters and no greasy rats anymore for the few extra dollars hands down food made for rats seems to equal more healthy happier rats and happier wife and kids with the less smell. local feed store orders anything i can find so it should be easy to get
