WELL WITH THE CAGE BEING HER 'SECURITY ZONE', I'D LEAVE IT. MY CATS HAVE ABANDONED THE CAGE WHEN THEY'RE READY. I ONLY EQUIP IT WITH BEDDING, FOOD & WATER... I ALWAYS PUT THE LITTERBOX OUTSIDE THE CAGE. I DO THIS WITH S/N ALSO, I JUST LEAVE THE DOOR PROPPED OPEN, THAT WAY THEY CAN CATCH A BREAK FROM THE OTHERS. IT'S DIFFERENT HERE B/C WE HAVE NO DOORS NOT EVEN ON THE BATHROOM!! THEY WON'T FIT THE WC.
