I'm not crying! YOU'RE CRYING!
A decade ago, my girlfriend at the time and I adopted a 15 year old cat that was not being taken care of by his previous owner. They wanted to put him down because he was old, had diabetes, and was hiding and pooping under their bed because he was being bullied by their younger cats. We took him in, made him comfortable and gave him a wonderful last year of his life before he finally passed away. I still miss him (more than the girlfriend, humorously enough.)
