Ok thanks Gray.
Got stuvk at work Fri so had to move his latest appointment to sat morning. Bit of a nightmare as it was a different vet and all she really did was give him another injection. Bit of a pain as she charged £30 for the privilidge and the nurse could of done that for £3. So we've got to go back again but I think I need to inist on something for home as its really unfair on him being dragged to the vets every couple of day.
