I agree with Donna, don't write anything at this point. Considering Ted hadn't slept and was faced with both a severe strike against his business and the loss of a cat, he was very professional and reasonable in the way he spoke to you this morning. He is very angry so expect some remarks that hint that they don't trust you quite as much, or that your future with them is not as certain as it was. Just keep going in to work and do your job well, letting Ted and his wife calm down and accept that accidents happen to everyone.
