A client of mine was recently given a couch by a neighbour. It was in good shape, and she badly needed some new furniture. She had arranged said couch in her living room, and been enjoying it for a couple of hours, when she noticed the sound of some muffled meows.
This client does have a cat, but she could see him pleasantly napping on the other side of the room. After a few moments confusion, she realized what was going on – the neighbours cat was stuck IN the couch. She pulled off all the cushions and fished the poor thing out from within the structure of the sofa. Apparently, the feline was none the worse for wear, and was safely returned to his owners. The neighbours swore up and down that they had no idea he was in there.
