Exercise:
Ferrets love exercise (playtime) they need lots of stuff like toys to keep them entertained, they also need supervised playtime out of there cage to keep them happy, but make sure they are never left alone outside of there cage because they can escape through just about anything. Some very good ferret toys are found around the house:
-Paper Bags
-Tennis Balls or Baseballs
-String
-Pop Bottles
-Tubes
There are so many things a ferret would love to play with but before you allow your ferret to play with something ask yourself is this safe? do i care if this gets destroyed? And can this hurt my ferret in anyway?
Healthcare:
Like on the Guinea pigs page if you think your ferret has a problem then go see a vet.
