Bunny in need, appeal for medical care money

My five year old female miniature rex rabbit 'Yoghurt' has unfortunately injured her eye while hopping around in the garden, possibly when exploring in the undergrowth etc, the scratch or poke has resulted in a rather nasty ulceration and require expensive treatment. If the ulceration has not improved by the 28th of this month (her next vet appointment) we have been informed her eye will need to be removed, in that case there would no longer be an issue.

However, we simply can't afford the operation and the only other alternative will be to have her put to sleep, otherwise she is a very healthy, happy and energetic bunny and it breaks our hearts to think of cutting her life short if there is a way of saving her.
