After almost a week of hospitalization and extensive testing, x-rays, ultrasound, berium series, etc., we decided to go to surgery yesterday morning on my kitty. The culprit was an audiotape that wrapped around the base of his tongue and extended down to a ball in his small intestine. The intestine perforated but the surgery was successful and he should be able to come home tomorrow. His "intestine contents" are in the bag next to the cassette that the tape came from. Ten days and $2250 later, kitty will recover! YAY!
