The 29-year-old socialite said that she couldn't bear to see her pet Kinkajou, called Baby Luv, killed even though it could have been infected with the fatal disease.
She told US talk show host Jimmy Kimmel, "I still have it. I have two of them at my ranch.
"It got a little crazy one night. Like ending up in the hospital crazy. It bit me! It bit my leg, and I thought it had rabies. So I said, 'We have to figure out if it has rabies, how do we do that?' And they said, 'We have to cut its head open.' I was like, 'Well is it going to live?' And they said, 'No!' So I was like, 'Then we're not doing that! I don't care if it has rabies or not!'"
But she stands by her decision, adding, "It didn't have rabies, obviously, I'm here today."
