Hey Heather!
Yeah, it's a bummer......I think the vets charge more for buns because they are considered "exotics", requiring extra schooling and coursework and staying updated in bun medicine since it changes so quickly...at least here in the US... I'm charged $29 per bun BUT if I want a Sunday or emergency appt it goes up to $54....
So needless to say I ration our appointments and have gotten pretty good at diagnosing health issues. Still I am sure I spend between $1,000-1,600/year for vet care but I feel my kids are worth it.... And let's face it, having 8 bunnies is a little over the top! So I spend the money gladly....

There are vets who do not have the advanced education in rabbit care who will try to care for rabbits and seem to think rabbits can be treated like a dog or a cat. We get horror stories all the time at the sanctuary about vets who tried to treat a much loved bunny and ended up seriously injuring the animal or even killing them, or at least giving incredibly stupid and harmful advice. What a waste and what arrogance on the part of the vet. Certainly it is the responsibility of the bunny owner to find a bunny specialist vet well ahead of time when his or her services will be needed.....www.rabbit.org has a great link on this topic.

Well, let me get off my soapbox.... I guess I care about all rabbits just a little too much and can get carried away when asked an opinion!!!! .

By the way, why don't you make 1 appointment for which ever bunny you think may have the ear mite problem. The vet can tell you if you have a problem or not. If you do, the vet will give you ear medicine...which you should then give ALL your guys since ear mites are catchy.... If you can establish a good relationship with the vet and indicate a strong knowledge of bunny health issues, chances are he will work with you and give you a small supply of medications. Good Luck! Letter on it's way to you. My best to you, Bunny, Cadbury and Twinks...

By the way, did you have a birthday party for them???? LOL!!!!
