After all the ups and downs with Harry's health over the last few years we have decided that, while he's well, we're only taking him to the vets for his annual jabs and a check up. If the vet wants to do blood tests when we're there then fine but he's not going especially for that. His cat sitter (a vet nurse) agrees it's the right thing for him.
Obviously if anything changes we'd be there like a shot, but right now we're going to enjoy being his slaves.
Here's the obligatory photo!
