Mackay was also quick to praise the strength of his squad, with several players coming in due to injury and performing well.
"I'm delighted that after 12 games we're in and around what is going on," PA Sport quotes Mackay as saying.
"I'm acutely aware how relentless and unforgiving this league is as well as how quickly your squad can be decimated by injuries.
"We have had some injuries in the form of Nicky Maynard, Craig Bellamy, Jordon Mutch and Tommy Smith. But other players have come in and grabbed the jerseys."
Cardiff have a three-point gap to Leicester City in second place.
