Cats can teach people lots of things about life if you’re just observant and subservient to the cat’s needs. Since cats have a much shorter lifespan than most humans, cats can teach us how to deal with aging.
Some important lessons about aging is to be honest about your limitations. You’re no longer young so don’t expect your body to be able to do thing sit could do forty years ago. Also learn to savor the little moments of life. Take a nap and enjoy the moment like a cat would do. (Then again, cats never have to worry about paying the bills.)
