Hoilett had been without a club since being released by Queens Park Rangers this summer but he was recently snapped up on a free by the Bluebirds following the appointment of Neil Warnock as manager.
The pair had briefly worked together at QPR and the Canada international obviously did enough in that short period to impress the former Rotherham United boss.
Cardiff picked up a 2-1 victory against Bristol City in Warnock's first game in charge and Hoilett, who made his debut in the match, says he jumped at the chance to sign a contract with the Championship outfit.
"It's great when you have a manager who believes in you," he said. "I was 100% ready to go. I worked with him at QPR and he gave me an extra boost. I love working under Neil Warnock, so it was a no-brainer to come here to Cardiff."
Cardiff have now moved out of the relegation zone with what was just their third win of the season and they will be looking to keep the momentum going into the midweek home clash against Sheffield Wednesday.
