I agree with all that’s been said. Plenty of fresh water, raw meat and the occasional egg, I give mine an egg once a week. Plenty of bedding, shavings and barley straw. I’ve found shredded paper good during the summer months but not as useful in the damper weather. In time their coats will be good as new. I’ve had ferrets do this in the past, some of which have lived to 9 years old.
