Mine always have access to dry ferret food and in the evenings I give some type of meat. then remove the remains 1st thing in the morning. They will need cleaning daily and the best form of bedding I have found if you have no access to straw is shavings for both sleeping area and eating and excersise areas. If you clean out the shit corner everyday, and then the rest weekly. My Old friend feeds his on bread and milk but hes stuck in the old days and although his ferrets are healthy I dont recomend this. although his strain of ferrets have probably not been fed much else
