The people that had Charlie before me had him caged outdoors. Obviously in not very clean conditions. Usually the infection is asymptomatic and will clear up on it's own. The problem is with compromised immune systems. Charlie has insulinoma and when I started him on pred it must have lowered his immune system enough for the infection to take hold.
I get the egg toys from a friend on another list. They are those plastic Easter eggs with a crotched covering over them. My kids love them. My friend makes 3 different kinds: plain eggs, eggs with tails (snakes), and with tentacles (octopusses). She puts bells and things in them so that when the kids shake them they make noise. Lynn charges $12/dozen and they are well worth it. I buy a couple dozen a year to replace the ones that have broken and to give as gifts. Sometimes she lists them on ebay but doesn't have any on there now although someone else may. I always just email her and ask her to make me some. I know Heaven Scent Ferret Shelter (fuzzyslave@aol.com) got some donated by her not too long ago and may still have some for sale.
