I'm sorry to here about your cat. I was never really a cat person, but losing any animal is hard. I had a boxer that was my best friend growing up. He got MS in his back legs when he was about 9 years old. He used to stay outside in a fenced in area around the back of our old house. When we moved to the new house we had to keep him in the basement all day because we didn't have a place for him yet. I would take him for walks and we would sit outside when I got home every day. After a while he couldn't use his back legs at all. We had to have him put down. It was sad, but he was better off. I don't know your religion, but I can picture my dog running around heaven chasing birds and rabbits . Maybe your cat is right beside my dog chasing them too
