Kitties are so funny. My Sam (like your yellow & white) got into the thread on top of my machine and pulled it out of my sewing room, thru the DR and into the kitchen. AND had swallowed some of it.And I'm so careful to shut the door behind me. Be very carful of pins, also.Sam had a needle (no thread on it) in his mouth.I saw him trying to swallow something, looked in his mouth, didn't see anything, he kept trying to swallow..I checked again and it was flat on his tongue. It scared the crap out of me.
