Joe Exotic thinks he could die in prison.
The 'Tiger King' star - who is currently two and a half years into a 22-year sentence after being convicted of plotting a murder-for-hire against his rival Carole Baskin, as well as other charges - is concerned the prison system aren't addressing his various medical issues in the way they are supposed to and his health is now "deteriorating by the day".
However, Joe has vowed to use his fame for good if he ever does get out of jail.
He told 'Entertainment Tonight': "I have CVID, which is a common variable immune disease, which means I have no immune system, and I have to get blood infusions every three to four weeks, and I've only been getting them every three months.
"I was weighed again last week and I lost another 10 pounds, last week alone.
"I have hemoglobin anemia, which is another blood disease. They used to take me downtown to the cancer center for treatment but we stopped doing that.
"I refused treatment for tuberculosis last week, I'm dealing with another disease, my mouth is full of ulcers. I cannot eat. I look bad.
"Listen, if I live through this because my health is deteriorating by the day ... I'm gonna do nothing but go around the world and help the kids that have been born with cleft palates and fix their faces. OperationSmile.org is one of my favorite charities that I am going to get behind and we're going to turn this into something good...
"I'm [also] gonna stand for prison reform and justice reform."
Carole's husband, Howard Baskin, recently said the couple would help with Joe's campaign for early release if he supported the Big Cat Public Safety Act, which was passed by the House of Representatives in December and prohibits the private ownership of big cats, and the 58-year-old former zoo owner - whose real name is Joseph Maldonado-Passage - wants to accept their offer, but with conditions.
