Make a fuss of your own cat so he understands he's still the boss & home is still his territory.
Take something that smells of each cat (like a cloth or t-shirt) & introduce it to each other - so they can get used to the other's smell. If you litter trays - swap the litter trays over regularly for the same reason.
Wait for your cat to come to the kitten, not the other way round. He will become curious about it..”
We did something similar.
1. Kitten had its own room, and wasn't allowed out of it for a week.
2. Kitten was allowed to roam around the house when the other cats were out, so that he could smell them, taste their food, etc., but didn't see them.
3. During the same period, other cats obviously became aware of kitten's presence through sniffing around his door, and later sniffing him in the rest of the house.
4. Graded introduction of kitten to cats - one older cat at a time was allowed to enter the kitten's room under supervised conditions, just for a short while. Door remained open, so cat didn't feel threatened. There would be some scuffling and batting of paws, but I've never had any serious problems.
5. Once kitten and older cats were able to socialise without any agro, kitten was allowed to roam around the house. Older cats would smack it down if it got too annoying, but the social order was established pretty quickly.
