Fingers crossed for your little one.
Totally agree with your point of view: I can't stand most of vets, too, because from our experience biggest majority of them don't know what they are talking about at all when it comes to guinea pigs, but feel obliged to say something, because they represent a practise that has to earn money: that's their ultimate aim: to earn money, it's business, in the end - unless it's a cavy charity, like CCT. Some of them genuinely want to help, but aren't able due to lack of knowledge and some of them don't have a clue, feel free to charge for a so called "consultation" when they tell us something, which I later find out doesn't even apply to guinea pigs, but only to rabbits. We live in London and literally every single vet in Clapham/Battersea areas are so poor, it's hard to believe how useless they are even though some claim they have experience with little furries. Only Vedra helped us in the end, otherwise our little one would have suffered and eventually died painfully after months and months of illness and medicines that were totally unsuitable for his condition and did harm. It's extremely tempting at his point to sue some of our previous vets that wasted our time and made our pig suffer more, but I'd rather go back when everything is ok, share the experience of successful treatment and the whole history, perhaps that might help some other poor piggies that get into their unworthy hands.
