This one is simple :-)
 
1. Take a drill and drill holes in each or the corners of the pan, towards
the top.  If you don't have a drill, a hammer with a nail will also work.
 
2. Go to your local K-Mart/Wal-Mart etc and purchase a package of metal
shower curtain hooks (generally around $1.50 for a dozen or so.)
 
3. Clip the pan to the cage with the hooks.
 
4. Laugh you butt off watching the confusion when she tries to tip the pan
and can't :-)
