I'd worked at my local humane society for about a year when I first met George. We were situated in a weird part of town, just between the country and local tourist attractions, so very often we got the strays caught by amusement parks and unwanted barn cats. George came in one day in a trap, dumped off by someone looking to rid their yard of cats. There really wasn't anything special about him at first-- we tested him for FIV, gave him his shots and dewormed him, then we put him in a cage and he promptly tore the insides to bits. He quickly shredded any signs that were attached to the outside of his cage, and the next morning I had the nerve-wracking job of cleaning out a completely ransacked cage that still had a feral cat in the back corner.
However I quickly learned that George was different. George and I had a friendship from his second day, when he sat very quietly at the back of his cage and let me clean it out. I didn't need gloves or a net or a dozen curse-words like with most of the ferals. I simply cleaned him out and closed the cage and George didn't move. The next morning his cage was completely destroyed and I again cleaned it out with George sitting at the back watching me.
We did this dance for about two weeks, until I finally made the decision that I was going to touch George. I told my co-workers that he'd never hissed or made any sort of warning sign and I wanted to see what he'd do. They watched through the window in the closed door as I reached back and touched George on his pink nose. He didn't move. I scratched the bridge of his nose for a second and closed the door.
We went through this ritual for a few days, George in his corner getting his nose scratched. He never growled, hissed, or tried to escape. Every day I dutifully cleaned out his cage, gave him some treats, scratched his nose and left him alone. Every night he did backflips and shredded his newspaper, spilled his litter, and ate any nametag we left on the front door.
Until one morning when I came in, and George hadn't torn up the place. I distinctly remember staring at him through the bars of his cage and knowing that today was the day we were going to be friends. He watched me with his unblinking stare as I opened his cage door and sat down in front of him. I scratched his pink nose, and slowly moved up to his head. George remained perfectly still. I wrapped my hand around and rubbed his back. I continued petting him for a few seconds until a low rumbling purr came out of his throat.
My George, the acrobat and cage-destroyer, rolled onto his side and stretched. George, the big tomcat who no one else would clean, was rolling over and moving closer to me to get his head scratched. I couldn't help but laugh. "Margaret!" I yelled to my coworker down the hall, "I'm going to put George in the cat room!" Our cat room was a sunroom where we let 10-15 cats live until they were adopted.
Margaret came running.
"You're going to WHAT?" She looked incredulous. I pointed to George, on his back in his spotless cage.
"He's a real cat now!" I laughed. Margaret didn't trust George, but I carried him to the sunroom. The second I sat him down, George meowed what I can only presume was a "thank you" and immediately went up to the other cats. He was sniffed and quickly ignored, acceptance. George curled up next to the window, snuggling another cat who was nice enough to ignore his extremely loud purring.
Now, George is a staple in the cat room. When the door opens, he comes ambling up to be pet and kisses your arm as you rub his back. He's grown a beautiful white and brown tabby coat and actually plays with toys! George is one of my very favorite cats at the shelter and not a day goes by when I can't see how appreciative that he is that we took the time to let him be a normal cat instead of a feral stray. This fall, George will be moving with me to whereever I end up (still waiting to hear from a few Masters' programs!) and I can't wait to have him as part of my family.
I wanted to post one here just so maybe we'll all share some of our stray stories! If you can't use it, don't worry, I just like talking about George.

I tend to ramble, so sorry it's so long! (If it needs to be shorter, let me know and I'll make an abridged version!)
