I: Gerbil's box to sleepingplace

[LEENKNEGT-LIOEN]

Hi,

 I made for my gerbils a gerbil's box, you know, like in cat's box. It
worked,but they kept kicking the cat litter out. For that I put a clay
pot reversed on it. Which made a nice, cute hole for them with an
entrance on the top.
It seems to work a bit too good, now they've started to sleep in it.
Just a moment ago, I saw they also have put some hay and stuff in it!
And they still use it as a toilet! Gerbils! <sight>
Thanks for reading my little story! :0)
