Mackay spent six years as a player with the Canaries, and the former defender has praised the club's supporters for the atmosphere that they create at their home ground.
The 41-year-old told Wales Online: "Carrow Road can be a very intimidating place to play.
"I was there the year we won promotion. It was the year they opened the new stand and there were 28,000 there every week and the atmosphere was incredible a lot of the time.
"We'll be going there looking for a positive result, but we are aware of how difficult a game it is going to be."
Cardiff will slip into the relegation zone if they fall to defeat against Norwich.
