I would put things that smell like the new cat around the older cats, and do the same with things that smell like the older cats with the new cat. Does that make sense? Let them "sniff" each other under the door, etc. and then let them have at it!

Can you believe I even responded to this message? Me, who has the "new" cat that has been here for 3 months, and my older cat has yet to accept him!!! But I have read the above suggestion many times from other cat people.


Good luck.
