An 18 year old diabetic cat who probably also had pancreatic cancer. Last week he came in and I had to set an IV catheter. While it is common for cats fight you during this procedure, his was actually difficult to set because he wouldn't stop purring and kneading my hand as I held his paw. His owners were elderly and didn't want to be with him when he passed. It felt awkward to turn my back on them as I carried the cat out of the room.
