If both cats did not fight the last time, you pretty much have a good chance.
When Larry (my avatar picture) first came to our house, he had been treated wrong by his former family and was scared of everything. He is 15 years old now.
I was sleeping in the livingroom on the floor due to back problems at that time. The first five days he hid behind the fridge and nobody saw him. His food and water however, was touched and he did go potty. I pretended to be asleep when he snuck through the house and left him alone. On the sixth day (well during the night) after eating and doing his 'toilet' he slowly came in and sniffed me from foot to head. I left him alone, and he layed down next to me, I still left him be (his nose was wet and cold and tickled).
After that night, we were bonded and nobody can come between us now.
I moved in with my BF for a while and he has a cat also. Larry puffed up and hissed, but left Tommy alone as long as Tommy did not want to sit in my lap. Now, after a few more years gone by, we four still share the same home and we are all alive and doing well. Larry and Tommy are not the best of friends, but they leave each other their own special place.
So, if you have a scratching post your cat loves, let him take it on the move.. or favorite blanket.. something that is only his...
Good luck.
