The heiress was not badly hurt but did visit a hospital emergency room to receive a tetanus shot, her publicist, Elliot Mintz, told The Associated Press on Friday.
Hilton was frolicking with her exotic pet early Tuesday morning "the way some people play with their cats and dogs" when the animal became excited, Mintz said.
"Baby luv bit her. It's a superficial bite on her left arm," he said.
Hilton, concerned that she was bleeding, called Mintz at 3 a.m., and he took her to the hospital.
"She was seen by a doctor, who treated the wound, gave her a tetanus shot, cleaned the wound and applied something to it," Mintz said.
The 25-year-old "Simple Life" star and her publicist left the hospital around 5:30 a.m.
Mintz said Hilton's arm did not appear to be swollen the next day.
She also felt well enough to continue promotions for her debut album, "Paris," set for release August 22.
Hilton's breathy single "Stars Are Blind" has already jumped up Billboard's dance music charts.
"Yesterday she did two photo shoots and two magazine covers," Mintz said. "She's OK, she's fine. Anyone in this situation would do well to have the wound looked at."
Baby Luv was checked out by a veterinarian on Wednesday.
"I don't view kinkajous as aggressive animals. The same kind of thing could have occurred with a German Shepherd," Mintz said.
