I lost my beautiful cat, Felix, who I found as a kitten, last year. As you can imagine, the house has been pretty empty. But my good friend has a daughter who tends to rescue kittens/cats. Nicky was cat #3 and the largest and only male. He really is the sweetest cat, but he also expects attention. And cat #2 who my friend's daughter found as a kitten was the tiniest kitten I've ever seen - even the vet wasn't sure she'd register on his scale. And the issue was that she was afraid of Nicky, insisted on hiding on a shelf in the bathroom. So my friend managed to persuade her daughter to let me take Nicky - she knows me and knows he'd have a good home - and keep peace in the house. So Nicky came home with me on Christmas and other than hiding the first day/night, he's managed to settle right in.
And none of my cats have gone outside, either, there are too many dangers out there. Plus, two of my cats I rescued from outdoors as did my friend's daughter with the littlest one. But we have sliding glass doors that look out on the woods, so Nicky has plenty of outdoor entertainment - we have squirrels, bunnies and the occasional deer.
