I have heard that the average life expectancy of a domestic cat in the United states is 6.1 years. I've also heard that there have been cats that have lived for over thirty years. Is there a way to put an educated guess on how much longer my 13 year old cat will live?
She is a small (7 1/2 lb.) domestic shorthair. She showed up at our door as a kitten of less than 6 months. She had 5 litters of kittens, and then was spayed at three years of age. She has never been allowed indoors, but has free access to our large barn. She has never had any health issues, and her eyes and teeth are in very good condition. She eats whatever cat food is on sale, plus meat scraps from the kitchen and a variety of rodents. She is a very easygoing patient cat and very good with small children. She is not (has never been) extremely active, but likes to hunt, follow people around the yard, and play with toys and string.
If nothing out of the ordinary happens, I feel like she should be with us a good many years yet. Is there a way to make this more than just a feeling?
