My Nigel died . Two weeks ago now, the day after we took him to the cattery for his holiday.
Paula at the cattery phoned me to say he wasn't well and she was taking him to the vets. The vet said he'd got blood clots that were cutting off the blood supply to 3 of his leg and he was in a lot of pain. After a long discussion and many tears (on my part not the vets obviously) I passed the phone to Adam and let him tell the vet to 'do the necessary'.
