During the romantic flower-giving season, cats should avoid lilies. Hobbes, a cat, was placed on peritoneal dialysis and medications to protect his kidneys, nervous system, and gastrointestinal tract. His blood pressure was monitored, and medications were adjusted as needed. After 12 hours of being in a medically-induced coma, Hobbes was allowed to slowly wake up and was placed on a special kidney diet and medications.
