Twice now I've introduced newcomers by keeping them separate for a long time first, and it's worked really well. Shut the newbie in an extra room. That place becomes hers, so she feels safe in a new environment and has a 'home base' to retreat to. And the current family doesn't feel so invaded -- they still have control of the whole house except for the one room with The Thing Behind The Door. Then just let it simmer. Expect two weeks at least.

Sniffing noses and eyeballs peering under the door give way to wide-eyed stares as you leave the door open when you go in to feed or hang out with the newbie. After a few days start leaving the door open so the newbie can wander into the main area when you're there to supervise. My most territorial cat was outside the first couple of times the newbie came out of the room and scouted the house, that helped too: the newbie could roam without getting jumped, and later the alpha cat could come in and smell the newbie around the house without having to deal with meeting her face-to-face yet. Soon the newbie started coming out of her room, and all the cats just hung out and oh-so-casually watched each other. After a few hours she'd wander back into her room, and I'd shut the door again so everyone could relax and digest that. Finally, after three weeks, I left the door open all night, and nobody complained. (It might have gotten there a week sooner, but I was out of town, so introductions were on hold while I was away.)

And this time I happened to end up with a big cardboard box on its side in the living room. It's perfect -- newbie comes out and hangs out in the box -- able to see everything, right smack in the middle of the family -- yet totally protected.

The key to this is small increments. Go slowly, don't push it. Never bring her out of the room, let her decide when she's ready to approach. Get bored with how anti-climactic it's becoming. Oh, and the newbie's door is ALWAYS open when she's in the main house -- she has to be able to retreat safely.

As I said, I've done it this way twice, and am amazed how well it works. The first time I hadn't intended for the cats to blend at all -- I was a guest -- so I did nothing to push them together. They just became aware of each other under the door, then could smell each other around the house, then the door just got left open more and more and finally there was no need to shut the door anymore.

The next time I blended cats I was too eager, with two new kittens, to bring them all together. I wasn't patient (the kittens were SO cute and I wanted them in the main house right away!!). It turned out to be a stressful, hissy, growly time for several weeks.

This time I kept newbie separated because she was so sick and frail. (See thread "found a kitty" on Lost and Missing Pets forum.) She needed to eat, sleep, and not have to defend herself. She's doing well now, slowly regaining her weight and health. It was easy to not rush the introductions. Granted, this strategy is REALLY tough to follow when the newbie is cute and frisky and you want to spend every waking moment with them!

The cardboard box in the living room is such a help! I'll leave it there for another day or so. The last two steps will be moving her food and litterbox to wherever they're going to end up, but I'm in no hurry with that either. ~Kimberly

Thanks for the information. We are constantly learning and all of this helps. I haven't had the introduction experience yet as my 3 babies were 2 brothers and a sister but we'll see what new ones come to our home in the future, so this advice will be coming in handy, at least for me, and others, I am sure.

Excellent suggestions! Thanks for posting them. We are currently introducing our two new kittens Elvira and Ellen to the other 7 cats here. It is going very well and we are taking our time with it.

The only thing I would add to your post is the use of multiple baby gates on the door will give more exposure between the established cats and the newcomer. You have to totally block any gaps remaining. I wouldn't leave the door open and gates up unless I was there to watch them. One day I heard Princess growling and I looked in the kitchen in time to see our cat Beau trotting through, followed by a little trotting Elvira! She managed to push the pillow we had tucked in a gap aside and shimmy through. I grabbed her and put her up before Princess could do any damage. She will be the last to meet them since she hates all cats.

With the baby gates up you can encourage interaction by putting the food bowls on both sides of the gates. That will keep them all busy and happy while allowing them to watch the others eat.

I can SO relate to your words, "The Thing Behind The Door" . You have excellent suggestions and I understand exactly what you mean by that phrase. It brings a mental picture to mind when I introduced Nickels and Frankee to the girls . "The Thing Behind The Door"!

Found another tactic:
As I clipped off all Sable's mats, and brushed her, I put all the fur in a plastic bag. (Rohan will eat fur clumps, so I can't just toss it in a wastebasket.) Rohan and Luna just found the bag and took a LONNNNNGGGG sniffing history of Miss Sable's travels. I'm quite certain fur holds smells that relate to fights, fear, mud, roads, and illness. They've been SO curious to get close enough to check her out, but she won't let them yet. They had their heads stuck in the bag quite awhile -- a good first alternative to giving her the olfactory equivalent of a pat-down.

i know, this is "off topic"
(but my english is turning out to be more limited i did expect)
let me say
Miss Sable is just looking wonderful
beautiful, safe, at home,
best wishes, sincerely Eva

I see by the picture that Miss Sable is beautiful....Just so wonderful you were able to rescue her...it was just meant to be. It's nice when something that is meant to be is a GOOD thing.
