I go to the Maison Dieu vets in Canterbury which are quite good, and they have a branch in Sondes Road, Deal. I don't know what the staff are like though. :?
I went with my mum to the one in Canterbury a couple of weeks ago for their jabs, and the vet there, Valeria, remembered mum from when we lost a rabbit a few years back ( mum had not been there since then I don't think) so C/Bury staff at least get to know their customers.
