Hi everyone,
 
I own three of the Marshall ferret play pens, conjoined together into 1.
They have worked well for a year, but one of my ferrets, my ornary escape
artist, has taught himself to jump 3' straight off the ground, grab the
top of the playpen, and pull himself over.  Any ideas on something I can
use to keep him in the pen?  Thanks!
