Orson passed away

Monday evening Alice took Orson to the vet, he had fluid around his lungs and was diagnosed with congestive heart failure. He came home with some medicine but was having labored breathing and barely able to walk around. By Tuesday evening around our bedtime he started moaning meowing and was panting like he ran a marathon. Alice took him to the cat ER where he passed away. Orson was a 13 year old Persian and has been with Alice since 1998 in Chicago, Seoul Korea and Lexington, KY with Tilda and I.
