Bunny amputation

My beautiful baby boy bunny (Cutie) fell and broke his leg badly. Unfortunately the Surgery to repair it is too risky as it’s the hind leg that has multiple fractures. So the Vet has recommended an amputation as best option for him which is costing up to £800. I don’t have any insurance and need help ASAP please. Cutie is so full of life and so energetic I know he will rule with 3 legs. I will update you along the way.
