Summarize the following:
Ferrets need a lot of attention, and they should receive a considerable amount of out of cage time every day. Make sure you have at least an hour to play one-on-one with your ferret on a daily basis, as too much cage time can lead to stress and illness.  Ferrets are very intelligent and active, so you need to be engaged in play. This is especially important for single ferrets, who can get bored without a companion. Take time every day to play with your ferret in ways that offer both physical and mental stimulation. Single ferrets need more attention than ferrets kept in pairs or groups. An hour is the minimum amount of time you should spend playing with your ferret on a daily basis. Take an old towel and wiggle it around your ferret to get them interested. Your ferret will start to chase after the towel. When they catch an edge, you can pull your ferret around the room. When they let go, start the whole game over again. This game also works with rope tug-of-war style toys, available from most pet stores. Ferrets like chasing, and they like to be chased. This makes tag a perfect game for a solo ferret. Chase your ferret around the room and gently tap it's head or body to tag it. Then, start running away from your ferret and let it catch you. Go back and forth as much as you and your ferret are both willing.  To make the game more fun for your ferret, get down on your hands and knees. This puts you closer to their level. Ferrets are notorious toe biters, so be sure to wear closed-toed shoes when playing a game where your ferret is supposed to catch you. Like dogs or cats, ferrets love playing with toys. They will tug on them, chase them, and chew on them. Keep some hard rubber balls, rope toys, and other sturdy toys around the house that your ferret can bring out during playtime.  The toys do not have to be made specifically for ferrets. Many dog and cats toys will work. Just make sure the toys are thick and firm enough that your ferret can't chew through them, and small enough that your ferret can move them around. Make sure that you are always there to supervise when you introduce a new toy to your ferret. You want to make sure that your ferret will play with the toy safely and that they won't swallow any pieces of it. Hiding treats allows your ferret to mimic some hunting behaviors. This game challenges their mind while keeping them active. Put a few ferret treats in different areas around your house, such as in a corner or under some furniture. Then, allow your ferret to run around and find them. This is a great game for single ferrets, since they do not have to compete for treats.

Summary:
Set aside play time every day. Use a towel to make a game. Play tag. Keep plenty of toys around your house. Hide treats around the house.
