We had that exact problem with our previous MH...our cat Lily is very much the explorer...she would get under that slide and we had a devil of a time getting her out...it was a pain but we did actually stuff pillows in both ends to keep her out...it worked even though she tried to get in...really have to wedge the pillows in...of course remember to lock the cats up when you pull the pillows out to bring your slide in...we forgot to lock her up one time when we were packing up ready to go and she flew in there...delayed our departure trying to get her out.Good Luck...
