Karter began erotic dancing while in Missouri and was named the state's Déjà Vu Showgirl of the Year in 2007. She later moved to California to pursue an acting and singing career. Karter fell out with her manager when he discovered she had been working as an exotic dancer. While continuing to dance in California, she eventually moved into modeling and, after signing with the agency LA Direct Models, posed for shoots with erotic photographer Holly Randall.
In 2009 she was chosen as the PenthousePet of the Month for June, and appeared on the covers of Hustler in April and Adult Video News in June. She was the most searched pornstar in FreeOnes.com in April, with more than 145,000 searches, was also elected the Twistys Treat of the month, and entered Fame Registry list of the top most popular pornstars.
She also was featured on the cover of Holly Randall's photo book Erotic Dream Girls, which was published in October 2009. In January 2010, she signed an exclusive performing contract with the production company Zero Tolerance Entertainment.
On January 2015, she had her Twitter account shut down. Kagney went on a Twitter assault, aimed at Chris Brown, claiming he began bullying her online. Karter responded with a series of angry tweets, which are now gone, as well as everything she tweeted, after Brown's legal team got her Twitter account suspended.
