Ditto the above response, it can take months.
I've found that it helps if you feed them together (in the same room)
but from different dishes. I give my 3 (now 4 -- got a stray kitten
today) guys canned food every day @6pm, and when I added cat #3 5 years
ago, I fed the new guy from a different dish, then moved it closer to
the others every day.
