Elaine - she's your baby thats why you are getting het up and I know why in fact I would be on the roof with you. But try to keep a calm - Eva will be better for it so will you in the long run.
Tell them you will only see the vet you wish to see not the others. I found that with my vets they put me onto someone else who I had to start all over again with with (as our vet had left "Pablo") Cleo and we did not Gel as soon as I took her out of the carrier he went to grab her by the scruff of her neck -
MAJOR WRONG MOVE THERE ON HIS PART - I almost removed his head with my temper - must say here he never actually made contact with her scruff had he had done I would have killed him not merely had a go, she is an old lady and has never ever been lifted by her scruff.
He listened and I think he tried to get on track again but the line had been drawn as far as I was concerned when he told me "she's lost weight since the last visit and she getting on" that was it I picked her up put her in the carrier and he said "where are you going" I said I am waiting for " XYZ" you are not touching my cat.
Oddly enough I have seen him since with the dogs for boosters and Tess's poorly ear and he was great. Maybe an off day.
But the point is tell them who
you want to see its your money your cat your health and temper.
Sure she will be fine though.
