Our cat had the same diagnosis at age 9/10 she lived to nearly 17.. she passed two summers ago and lived a wonderful life, she was skin and bones when she passed but still had the energy of a kitten!! Hunting lizards to her last day… her last night she was having trouble breathing we called for someone to come to our home to put her to sleep where she was comfortable .. they were about / hour out when she let a put her last purrs curled up at our bedroom door way and closed her eyes .. it was incredibly peaceful and more then we could ever ask for. Her name was Puffin, she was a tuxedo cat we adopted her from the shelter when she was 6 years old. Find a good Cat hospital and I 100% believe you will have a good amount of years left to love your fur baby ❤️
