Okay - Now I understand where I got the info that gliders can't get fleas: Gliders-R-US. Figures. And, that information is quoted all over the web. When I was first researching gliders I came across their website. Didn't know they were a mill then.
I did read something interesting today: Putting fresh Eucalyptus leaves and sticks in their cage will keep fleas away. Apparently, you should put a leaf in their bag(s) also. I have no idea if this really works. The following site is one of the places making these claims: www.eucproducts.com/
Anyone ever try eucalyptus?
