However, within minutes of the spraying this otherwise very healthy young cat literally fell out of the window.  When my wife heard Calvin collapse she called me into the room, I immediately went to aid Calvin who had fallen and was laying on his side in distress. He was having what looked like a mild seizure and gasping. I picked him up and we ran with him to a local animal ER vet. Unfortunately  he died on the way. The Vets at the ER did look him over and saw no obvious signs of a cause of death, no obstructions in his airway, no wounds, etc. Calvin was only about 1.25 years old. He was a VERY healthy and energetic young cat. At about 18 lbs, he was very strong too.

Calvin, had been a feral cat we captured on our back doorstep with the assistance of the "Spay and Stay" organization (http://www.spayandstay.org/index.htm)   approximately one year ago. As part of the Spay and Stay treatment he was given a full physical exam prior to neutering, he was neutered, and given full battery of vaccinations and treated with Revolution for fleas and worms. Since that time Calvin has remained in our home as an inside cat, NEVER going outside. Calvin's death is truly a senseless tragedy as had we known of any risks to him or our other pets we would have had all the windows and doors closed.
