Through the use of the Internet Archive, we were able to uncover a page from the Wildlife On Easy Street website that explains how a cougar almost died due to Carole Baskin's carelessness (emphasis added):
It has been four heart wrenching hours that the little darling of Easy Street has been in surgery. We are all praying, all waiting breathlessly for word as two Veterinarians and a staff of techs hover around the stainless steel table. The life of one of the sweetest little cougars ever to chirp his way into my heart lays motionless before me and I feel helpless. He had been so sick with a non descript virus that I had thought surely would cost him his life. One day he was healthy and mischievous, the next he wasn’t eating and by the third day he had a feeding tube installed in his esophagus and was having series of shots throughout the day and night to battle the infection and slow the vomiting. Every day he looked worse instead of better. X rays had been negative, blood tests weren’t of much more help and every day he was hating the shots more and more. Finally he took a turn for the better and began eating on his own. We removed the feeding tube and were thrilled to be on the road to recovery.
