I think i might have to decide to have my cat put to sleep. He will be 16 this year. He's diabetic. We had it under control for more than a year, then he had a few uti's and we've just lost it with the diabetes. His blood sugars are either off the chart too high, which leads to organ failure, or dropping like a stone to below 4, which risks going into a coma. I'm up with him now having had an alert from the sensor he's got on. Had to give him honey to eat and ring the emergency vet. The trouble is he seems fine in himself?! He's eating, drinking, up and about, purring, comes for cuddles every day. If he seemed more ill it would be an easier decision.
