Make your fids cage nice and comfy with a snug place for them to sleep , they do sleep in nests in the wild...I use a Jolly ball with a fur liner which I can remove and wash..the boys love it..But if you don`t have a large cage you can still provide a sleepy place...

This is where I got my Jolly Ball from size 10inch ...Its expensive but IMO worth the money can be washed easily and the metal is all stainless steel the only safe metal for fids...

Other members will also have links to less expensive balls and you can just buy the ball without toys to cut costs then add your own..

Can members post their links to the less expensive Jollyball with out toys , always good to have a few different options...
