Last night a friend called me. I was at the store, so I let the call go to voicemail. When I checked the message I couldn't hear anything other than what sounded distinctly like a kitten meowing. Strange.
About an hour later my friend called back. I answered the call and she told me she had spent the evening at her grandparents' house. All evening long she kept hearing an odd whining sound. She thought perhaps it was some sort of machinery...but she said it sounded just like a kitten. She mentioned it to her grandparents, but they didn't know what it was. The evening progressed and the whining continued. Finally, the family decided to investigate. They searched the whole house and determined the noise was loudest in the kitchen. It really did sound like a kitten. A loud, upset meowing kitten. They looked in all the cabinets, behind the fridge and even pulled the dishwasher out to inspect the cavity behind it. Then they examined the walls and ended up removing an electrical outlet from the sheetrock.
My friend put her hand into the hole in the wall...and pulled out a kitten. Yep. There was a tiny kitten INSIDE the kitchen wall. She said it was dirty and covered with insulation. They checked the perimeter of the house for holes and couldn't find any openings. They have no idea how it got there.
