I gotta say that this little guy is absolutely amazing. He's been living here with us since June 1st, less than a month, and the changes in his behavior have been incredible.
Don't get me wrong - he's still extremely wary of Sam and Harley (Harley, being a typical tortie, is much more aggressive towards him than Sam), and he runs and hides under the table in the living room whenever he hears a loud noise, or when David comes into the room. But the bonding he and I did when he lived at Animal Aid has continued, and we've established what seems like a decent trusting connection. So when I wake up and finish my morning 'duties' (make coffee, clean litter boxes, put out a few Greenies for Sam'n'Harley) I now go into the living room and call out "Caruso!". Within seconds, he's out from under the table, leaping gracefully up onto the love seat, and we start a little love-fest. I never dreamed that he'd respond to my calling him in such a short period of time, or that he'd have the courage to curl up on a pillow next to me on the love seat and fall asleep - but that's what he'll do now. A week ago, when I'd stand up and leave the living room, he'd be back under the table in a flash of gray fur; in the past couple of days, he's stayed on his pillow, in a cat-curl, with his head on his front paws, and continued to sleep even though I'm no longer there to protect him.
Oh, and he comes by his name honestly, that's for sure. He'll yowl whenever he's moving from one space to another in the house, or when he wants me to come in to the living room and spend a little time with him. And his purring can fill the room!
My guess is that I won't see three kitties curled up in bed with us when I wake in the morning for quite a while, but things are definitely moving in the right direction.
I'm so, so glad we were able to adopt him. Most people who go to shelters want to adopt the tiniest kittens and puppies (who wouldn't - they're adorable!), but we opted for slightly older cats when we brought Sam and Harley into the family (they were four and five months old, respectively) and now that we've adopted a senior kitty, I can see us continuing to do that in the future.
Hell, I'm older and sick - why should I discriminate against a cat with the same demographic?
