When I brought Cole home from the vet(had him neutered and checked before he came here), Oscar had been here almost a year.

I had set up a separate room for Cole in the bathroom - litter, food, a towel rolled up and curved around like a cat bed.

As bcboat says, they get to sniff thru the door a bit...I would open the door, and stand between them, but not in their line of sight. They would sniff noses; and because Oscar was so bonded to me, my reassurances to him helped a lot!

It was several days before I let them both wander while I was home...and when that was okay, I left them alone one afternoon while I was at work.

They had the traditional 'snarl-hiss-swat' exchange - it's a cat thing!

A week after Cole's arrival, they were galloping down the hall playing!

Let us know how it goes!
