Hi, quite a long story, but the main reason is that we did change to the only other vets within a reasonable distance, as i wasn't happy with some treatment that my local vets did with my horse quite a while ago, anyway, they were fine and i was happy with them for a while, until one day i could'nt get to them, as its quite a distance, so i took my persian cat in an emergency to the local one am with now for quickness, and the long and short of it is that they found he had a bad heart murmer, which only two months previous he had a full health check over for his booster at the other vets and they said he was full of health, how could they miss that???/. So long and short is that i don't trust the other vets now at all, so had no choice but to come back to my local although them finding the heart murmer has give'n me some confidence back.
Hope that makes sence and answers your question,
