That morning, I called and called and called Angel. She had no response at all.  It was so unusual.  I was running up and down stair around and got nervous deeply.  I did not see her went up stair, and no signs of broken window.  Finally, I heard her very lady murmur.  but Where was her?  After I did the whole house search again.  I decided to take a look of the under of recliner.  I was very careful about this every time I got up from recliners.  But, after hopeless searches, I wanted to search those impossible places, under recliner.  Well, NO, SHE WAS NOT THERE.  WTH, where was this little elegant lady?  Let me do the second look.  Ha, I saw her white tail.  She was stuck in between, recliner back and, she was not able to get out.  I moved the heavy recliner sofa.  Yes, she was stuck in there, she even could feel my hands.  BUT, how did she get in?   Usually, cat could get in then it has no problem to get out.  BUT, she could not.  I almost to cut the recliner out to get her.  Before that, I tried to expand the recliner again.  wth, she was out.  How did she get in?  She got into that small place while I was sleeping on that recliner. God! 

The reason I took the following picture was because I want to take a closer look before I cut the sofa.
