Well... I think I have finally found a good home for my sweet, little Quinn.
I had placed a flyer up in the breakroom at work and our young security guard responded very enthusiastically! She has another cat about Quinn's age and really wants to take him home to join her family.
She is coming over tonight to pick Quinn up. I am very happy, although it is a bit bittersweet. I love that little guy... but know he will be well-cared for in his new home. I did tell her that, if for any reason, she no longer wants him... or the cats never warm up to one another... I will always take him back!
