Haruki Murakami said this quote
“ Holding this soft, small living creature in my lap this way, though, and seeing how it slept with complete trust in me, I felt a warm rush in my chest. I put my hand on the cat's chest and felt his heart beating. The pulse was faint and fast, but his heart, like mine, was ticking off the time allotted to his small body with all the restless earnestness of my own. ”
