I'm so glad Clive is better. I went through this disease Heamobartonella with by dear Theo. He was diagnosed with it after extensive testing and other problems . They figure it came from a flea bite even though he was an indoor cat !!
It started with pancreatitis which he survived and then hemo. He would crash and we would rush him to the vets and they always thought that it was it but he would revive. They would laugh cause they said he had 99 lives not 9. Theo was 11 when diagnosed so it was more difficult to treat but he was a fighter and had a good quality of life for a few years. There were the problems of not eating and aenemia and on and on. PM me if you need support with this at any time. Again he is young and strong and with your help can have a good quality of life.
