OK, latest update is, vet convinced that bandage will do no good because he will have it off in a trice.
Says Fuciderm is not a steroid but an anti-bacterial, and while a perfectly good treatment it should be covered by the Bytril an there is always the lick-off problem.
But more than happy - to the point of kicking himself for not thinking of it sooner - to refer us to an 'exotics' practice nearby which has a good reputation for rabbits.
That is set up for tomorrow. It will cost us, but I intend to try to recoup from the manufacturer. If anyone has any advice on the best way to do that, please let me know.
Turns out so far our vets have made no claim to Pfizer despite treating Benji for free - I told them they damn well should do!!
