As some of you may be aware, I am inviting an outside cat whom I have been feeding for about six years now to become an inside cat, not as a replacement for Bubba, who cannot be replaced, but because I don't think Ella really wants to be an only kitty, and because I'd like to be able to give him a stable home in his latter years.
By way of background, a few years ago, when I was still letting Ella go out during the day, one day she didn't come back when called, nearing dusk, so I went looking for her, and found her sitting next to a large gray cat, whom I now know as Smoke. Generally, Ella doesn't like cats, and may be allergic, so that impressed me. They weren't cuddling or anything but they were sitting within inches of one another, while Ella was ignoring me.
For the past year, I have been feeding the outside cats in my enclosed porch, which has a sliding external door that I leave open just enough for a cat to come and go. There are a couple of other cats who come into the porch to eat, and when I pick her up so that she can see, through the window, whatever cat might be in there, Ella would immediately hiss at every other cat, other than Smoke. She doesn't seem particularly interested in Smoke, but it's notable that she doesn't hate him.
Since shortly after Bubba's death, I have been preparing Smoke to become an insider kitty. I don't know how old he is, but he was an adult when I began feeding him outdoors more than six years ago, and he is not feral. He was someone's kitty once.
Last summer, Smoke would hang out with me in the backyard, watching me work on the garden, compost pile, and so on. He would sit a short distance away and just watch me. When I spotted him, I'd acknowledge him. Twice, he rubbed up against my leg, and once he rolled over onto his back. When I reached out to him, he slapped me a few times, but with claws in, as if to say, "No touching, please."
He has let me touch his nose or the top of his head several times, but in the past month, he has let me pet him once (although he was nervous about it), and he let me pick him up once. He seemed okay about being in my arms as long as I wasn't holding him firmly. When I stood up with him in my arms, he was about to jump down, but then he saw the window on the door leading into the house and it was like, "Oh, wow! What's in here?" He spent a few moments looking through the window into the house before wanting down.
My goal is for him to willingly come into the house. so I have been inviting him in from time to time. He appeared to be thinking about it a couple of times.
Sometimes, after he has left, I will close the external door, and let Ella explore the porch, so that she could get used to his scent, and it did not seem to concern her in a negative way.
The day before yesterday, while Smoke was on the porch, I picked Ella up, and opened the door, introducing them. Nobody hissed, I was going to bring Ella down to floor level, and Smoke backed up a couple of steps, which seemed like a sign of respect towards Ella. He wasn't scared, and neither of them were uptight about it. Since I was holding Ella, I couldn't see her face but she was looking at Smoke and her body was not tense.
So, that's where we are. Smoke is a handsome gray short-haired cat, who appears to be very healthy for an outside cat. I think he lives, much of the time, in a falling-down garage in a vacant house next door because I often see him in that yard, and he sometimes watches me from the trunk of a tree that had fallen down in that yard.
